Miniature CO2, temp & pressure sensor.

The new EE895 sensor module from E+E Elektronik measures CO2, temperature and ambient pressure. The small 3-in-1 module is an ideal choice for measuring instruments used for ventilation and climate control, in building automation or for process control. Due to its low power consumption, the module is also suitable for battery-operated devices such as hand-held meters, data loggers or wireless transmitters. The temperature and pressure compensation ensures high CO2 measurement accuracy under changing environmental conditions.

Additionally to CO2 concentration up to 10 000 ppm the EE895 module measures also the temperature and ambient pressure. The pressure and temperature compensation with on-board sensors minimizes the environmental influences onto the CO2 measurement. Thus the module offers a constantly high CO2 measurement accuracy, independent of altitude or changing ambient conditions.

The dual wavelength NDIR CO2 measuring principle with auto-calibration ensures long-term stable measurements, as it automatically compensates for aging effects and is particularly resistant to contamination. The factory multi-point CO2 and temperature adjustment procedure leads to an excellent CO2 measurement accuracy over the entire temperature working range of -40...60 °C (-40...140 °F).

The measured data for CO2, temperature and pressure is available on the I2C or UART interface. The very small dimensions of only 35 mm x 15 mm x 7 mm (1.38" x 0.6" x 0.27") and various mounting options facilitate the design-in of the sensor module.

The EE895 module can be flexibly configured via the digital interface. The CO2 measurement interval can be set according to the application and the power requirements.

With the separately available EE895 Evaluation Board, the sensor module can be tested on a PC. The free evaluation software displays the measurement data in graphical form and allows the user to set the sampling rate and the measurement units for temperature and pressure.

Detecting power transformer air leaks.

The new method, based on measuring total pressure of all dissolved gases in the power transformer insulation oil, will help customers detect andrepair any air leaks early. This can extend the lifetime of a transformer and lead to significant cost savings.

A uniquely accurate and reliable method for detecting air ingress in sealed power transformers is being brought to market by Vaisala. With the increased number of sealed transformers, ambient air leaks have become a significant issue as oxygen acceleratesthe aging of paper used in the insulation.

Measuring total gas pressure (TGP) is a step forward from the traditional measurement methods that are currently available in the market to detect air leaks. An oxygen sensor cannot detect an air leak, if there is a reaction in a transformer that consumes oxygen. Even if all oxygen has been consumed, TGP value will still give a reliable indication of a leak because the nitrogen value will both dominate and increase over time because it is neither formed nor consumed in the transformer. Additionally, TGP measurement can indicate if the nitrogen cylinder of a nitrogen blanketed transformer is empty – another task that oxygen measurement cannot detect.

“We are always looking for new solutions to help our customers to optimize their measurement needs and therefore wanted to develop an innovative, accurate and robust solution for detecting air leaks in transformers. We are very happy now to introduce this innovative new method, based on measuring total gas pressure,” says Teemu Hanninen, Product Manager from Vaisala’s Industrial Measurements.

The new measurement solution will be made available to the current customers via a software release for Vaisala’s Optimus™ DGA Monitor OPT100, which is the world’s first maintenance free dissolved gas analyzer for power transformers. For new OPT100s, the new software will be incorporated as a default factory setup.

“We are delighted to offer this software upgrade to our existing OPT100 customers and support them with an even more comprehensive solution unlike seen in the market before. Striving to develop both new solutions and improve the existing ones is deep in Vaisala’s DNA.”

Support safe reopening!

Omron is supporting the safe reopening of spaces after lockdown with a wide range of optical sensors. These components can form a vital part of an effective infection control regime within buildings, rooms and even crowd-controlled spaces by monitoring body temperature measurement, counting the density of people in an area and reducing the need to touch surfaces.

Commenting on the range, Gabriele Fulco, European Product Marketing Manager for Omron, commented, “Opto-sensing technology has an important role to play in coronavirus countermeasures and no-contact sensors provide a solid basis to solutions for access control and body temperature measurement. They can also replace ‘touch-based’ switches to operate lights and other services with the potential to becoming the norm once COVID is a distant memory.”

Omron D6T thermal sensors are based on an infrared sensor which measures the surface temperature of objects without touching them, using a thermopile element which absorbs radiated energy from the target object. The D6T 4x4 sensor can measure face temperature at distances up to 1m for access control, whilst the D6T single-eye sensor is more suitable for wrist or forehead wearable devices. With suitable calibration, the temperature accuracy on the D6T 4X4 sensor can reach ±0.2degC, giving a reliable identification of fever, and a matrix type sensor makes it easy to separate human and background temperatures.

The Omron HVC-2 image sensors can detect faces, facial features and human bodies, even estimating age and gender of the humans in the captured image. Basic sensing functions could aid distancing in the workplace or public spaces by counting the number of people in the room or detecting when people are too close together. The sensor can also reduce physical interaction for customers who stand in front of digital signage, providing targeted messages to people in at-risk categories.

The Omron B5W-LB LCR contactless switch can be implemented in environments where the spread of harmful bacteria and viruses needs to be reduced, such as doors, drinks dispensers, light switches, soap dispensers and toilet flushes. The sensor is distinguished by the reliability and repeatability of detection performance, even when presented with target items of different colours and types of surface, including reflective surfaces. Long detection distance and a convergent light beam triggers accurately on an object within a tightly specified target area, ignoring any objects in the background or foreground.
