Accelerometer

Damped, low mass DC response accelerometer
for high reliability impact testing applications


Endevco has introduced Model 7264G, a patented, damped MEMS accelerometer for crash sled, rough road and other critical shock testing applications.

Model 7264G features a full bridge, with two fixed resistors to facilitate shunt calibration. Sensing elements are housed within a rugged, lightweight aluminum, for a total weight of just 1.4 grams. The light damping of the instrument enables the unit to attenuate resonance and minimize phase shift over the useful frequency range. Full scale output is 400 mV with 10 Vdc excitation. Units are available with less than 1% transverse sensitivity (“T” option) and less than ±25 mV zero measurand output (“Z” option). A uniquely advanced micromachined monolithic sensor design offers improved ruggedness, stability and reliability, with added damping capability.

The sensor delivers shock resistance of up to 10,000 g in any direction, with a range of +2,000 g full scale. With frequency response extending down to DC (steady state) and integral mechanical overrange stops, the accelerometer is ideal for any crash or shock application where measurement of long duration transients, with minimal mass loading and broad frequency response, are required. This includes non-automotive applications, such as in shipping container shock tracking, ejection seat and jack hammer testing.

Because Model it has the same seismic mass, center of gravity and bolt hole spacing as the industry best-selling Model 7264C-2K accelerometer, it may be used as a drop-in replacement for legacy applications, where damping capabilities are an added benefit. Model 7264G meets SAEJ211 and SAEJ2570 specifications for instrumentation for vehicle impact testing, as well as multiple other global automotive testing standards.

Historian process video

Process Historian added to Video System
By integrating with the process historian from Canary Labs, Longwatch can not only display all the data from an event, it can show video of what happened out in the plant.


Longwatch has announced a bi-directional OEM agreement with Canary Labs. The Longwatch Video Historian now offers Canary Labs Trend Historian and Trend Link software that enables users to link video with plant data. Together, the two systems archive all the relevant information—video and real-time data—from a process or automation system, making it much easier for plant operators and engineers to analyze events, alarms and actions.

When video cameras are situated to monitor process or automation operations—such as assembly lines, inspection stations, machine tools, pumping stations, tanks or similar systems—video from the cameras is stored along with real-time data from the process. If an alarm occurs, or operators want to analyse problems with a system, both the archived trend data and video can be “replayed” and displayed simultaneously using the Longwatch Viewer software. This allows operators and engineers to see all of the pertinent process data from the historian, plus view video of the process equipment, at the same points in time.

The Longwatch Video System can acquire video from both analog and digital cameras throughout the plant. Video data can be sent over existing plant networks, wireless or cellular links to a central server in the control room, where it can be viewed on HMI/SCADA workstations. Video can be viewed live, attached to an alarm message as a short “snippet,” or archived in the server along with real-time process data.

Canary’s Trend Link chart object, integrated into the Longwatch Video Historian for automatic visual synchronization of trend charts and video, can interface to other historical data archives using OPC-HDA. Similarly, the Canary Labs Trend Historian collection engine can obtain real-time data directly from PLCs, RTUs, data acquisition systems, DCSes, PC-based control systems, and other smart systems via OPC interfaces.

Video makes analyzing past events and trends much easier than simply looking at raw data and reports on a screen.

“Canary Labs has enabled us to make initial installations of our new Video Historian very easy and very capable,” said Steve Rubin, President and CEO of Longwatch. “Our Video Historian has received a great deal of interest from early adopters, and the inclusion of the scalable and powerful trend engine from Canary makes the product that much more valuable,” Rubin said.

“We’re pleased to be working with the innovative team at Longwatch,” stated Gary Stern, president of Canary Labs. “The engineering teams in both companies have a rich and successful history of satisfying the needs of industrial customers. With this relationship, we’re able to take the application of our product families to new levels and new applications,” he added.

The Canary Labs historian and trending component is part of the “Starter Pack” of Longwatch’s Video Historian software.

Dairy NIR application

Constituent measurement and quality control
Outdated legacy system replaced with in-line near infrared analyser


ESE has announced that Rockview Farms of Downey (CA US) has chosen ESE's Q5i Near Infrared (NIR) In-line Analyser for improving quality control during the fluid milk standardization process. Rockview selected this system based on its fast and accurate testing, and increased control for measuring key constituent levels. Fluid milk production requires tight control over both fats and solids levels in order to meet FDA compliance requirements and ensure customer quality and safety.


Q5 Series Near Infrared Analyser
ESE's Q5 family of Near Infrared Analyser is designed to help manufacturers in the food and beverage industries test and measure food constituents in a lab environment or right on the production line. The Q5 NIR Series will analyse a batch in as little as five seconds, contains no moving parts to ensure sample accuracy and repeatability, and can sample multiple constituents without preparation or clean up work. The Q5i has no moving parts, sits right on the production line, and requires little to no maintenance.


"Heightened consumer expectations and the FDA require us to continuously review our quality standards and find better ways to measure constituents like fat and salt," stated Joe Lunzer, Plant Manager of Rockview Farms.
"With the implementation of the ESE Q5i Near Infrared Analsyer, we will further improve the quality of our milk products. their system allows us to monitor and control the batch on the production line every 5 seconds, without pulling a sample. And, it instantly informs us when a batch is out of tolerance before sending it downline. We expect to have our location using the new, advanced in-line technology in production by mid-September."

"We are very pleased that Rockview Farms has selected the Q5i Near Infrared Analyser as their technology for inline fluid milk standardisation," said Tom Walther, President of ESE. "We take pride in helping our customers manufacture the highest quality products. Like many other food manufacturers facing the need to replace legacy equipment, Rockview chose our advanced in-line technology for its ability to quickly and accurately test multi-constituents and receive results within seconds, as well as deliver a fast return on investment and immediate gains in operational efficiencies. With the Q5i NIR In-line Analyser system, Rockview will be replacing outdated, legacy in-line units which would have required costly parts and long lead times, and not offered the advanced technology found in today's Q5i solutions from ESE."

ESE will work with Statco, a leading distributer in the food and dairy industry, to complete the full implementation of Rockview's fluid milk standardisation technology.

Electronic measurements acquisition

LEM announces the acquisition of Danfysik ACP A/S

LEM the market leader in providing innovative and high quality solutions for measuring electrical parameters, has acquired the Danish company Danfysik ACP A/S. The deal is a strategic bolt-on acquisition in order to strengthen the position of the LEM Group in the field of very high precision current measurements.

Danfysik ACP (Advanced Current Products) is the world’s leading company in the development and manufacturing of highest precision current transducers for three main markets: medical scanners, precision industrial motor controls and test & measurement. LEM has acquired the transducer activity with a turnover of CHF 7.6 million in 2008 and 15 employees. The company is based near Copenhagen, Denmark. The acquisition was finalized for an undisclosed amount.

Paul Van Iseghem President & CEO of LEM (picture right) said: “Danfysik and LEM can already look back at a successful 12 year relationship. We are taking advantage of this strategic bolt-on acquisition to create a new focus on the high precision current transducers market.”

Soeren Rathmann, Chairman of the Board of directors of Danfysik ACP; “We have been very satisfied with the development of Danfysik ACP, however the strategic fit to LEM has always been obvious and we believe that the company now has found its right home.”

The product range covers transducers for nominal current measurements from 12.5 A to 25 kA providing overall accuracy at +25°C from 1 ppm. Thermal offset drifts are extremely low, from only 0.1 to 2.5 ppm/K. Models from 12.5 A to 60 A nominal can be used for PCB mounting, models from 60 A to 25 kA are for panel or rack mounting.

To obtain these exceptional performances, Closed Loop Fluxgate technology has been used coupled with a top class current transformer. This combination enables high accuracy, dynamic performance and a wide measuring range.

Featuring galvanic isolation, all components can be used for current measurement of any kind of waveforms (including DC, AC, mixed and complex) without any contact to the conductor.

Atomic Absorption

New entry level flame AA spectrophotometer

Analytik Jena has launched the novAA® 350, a robust, simple to use flame-only atomic absorption spectrohotometer with the performance of a high-end system. Designed for daily laboratory usage, the new model features an automatic 8-lamp turret utilising high intensity hollow cathode lamps with a significantly improved lamp power supply for better performance and speed of analysis.

It is a fully automated flame system which is available for single beam or double beam operation. The high quality optics from Carl Zeiss have a unique special covering for protection against the most aggressive laboratory environments. The well-established D2 HCL background correction method ensures accurate analyses can be carried out even on samples with the most difficult matrices.

A built-in Self Check System utilizes a multitude of sensors to monitor key safety-relevant parameters such as gas flow, the burner and the siphon for contamination residue to ensure safe operation of the instrument. The flame is automatically extinguished in the event of a power failure.

A number of optional accessories can be used to further enhance performance. For large sample throughputs, a unique autosampler is available with intelligent online dilution. This provides automatic dilution of samples down to a factor of 1: 625 to eliminate errors associated with manual dilution. If concentrations exceed the calibration range, an automatic clean control prevents contamination of the subsequent samples.

For samples with particularly complex matrices, accessories such as the SFS6 injection unit or the Scraper can be of great benefit. The software controlled SFS6 injection system provides continuous cleaning and flushing of the burner heads to extend the available working time with samples with high matrix or salt contents. The Scraper is an intelligent software-controlled cleaning device for use with nitrous oxide flames. It automatically removes graphite deposits from the burner slot, ensuring continuous and reproducible measuring cycles for routine analysis and avoids the need to shut down the flame for cleaning.
