Analog and Digital Servo Inclinometer

Meggitt Sensing Systems has announced the North American market introduction of the Sensorex SX41100 series, a high-performance servo inclinometer family featuring analog and digital outputs and a maximum linearity error of less than ±0.02% FS. The series is designed to provide high-precision angular measurements within extreme testing environments, such as those typically found within civil structural alignment, crane and offshore platform safety systems, roadway and rail track leveling applications.

The highly robust Sensorex SX41100 series is designed to provide an output signal, proportional to the angle being measured, over a range of ±1° to ±70°. The series is also part of the company’s best-selling Rugged Enhanced Digital Sensor (REDS) family, incorporating Meggitt’s own proprietary Sensorex digital hybrid compensation circuit design (HCN module), resulting in high-performance inclinometers with ±5V analog, 4-20 mA or RS232 and RS485 ASCII digital outputs and built-in active digital temperature compensation, reliably operating over a temperature range of -40° to +85°C (-40° to +185°F).  Incorporation of an inertial mass with servo feedback, optical position pick-up and friction free mounting allow the Sensorex SX41100 series to provide high accuracy with excellent long term stability and high reliability. Because the inertial mechanism is immersed in oil, units have high shock and vibration resistance with a good damping factor.  Units also operate from a 9-30V unipolar power supply and feature IP65 environmental sealing.  Digital versions are delivered with software and digital data transmitted in ASCII format, allowing for direct communication with a standard PC, along with user-selectable parameters of data acquisition and display.

All Sensorex SX41100 series servo inclinometers are accompanied by a two-year comprehensive product warranty and are available thru Meggitt’s San Juan Capistrano, California, USA and Archamps, France-based facilities.

Miniature LDVT’s

For embedded automotive and laboratory test bench applications

Meggitt Sensing Systems has announced the North American market debut of the Sensorex model SX9W3, a rugged, high-accuracy miniature linear variable displacement transducer (LDVT), designed for high-precision displacement measurements within a variety of embedded automotive and general laboratory test bench applications.

With an overall length of just 26 mm (with body and core at null position) and a 9 mm diameter, the instrument offers a maximum linearity error of less than ±0.25% of full scale, with option to further reduce to ±0.15% of full scale. The transducers are designed to reliably operate over an operating temperature range of -40°C to +125°C (-40°F to +257°F) and are environmentally sealed to IP65. Meggitt’s Sensorex LVDT’s have no wearable parts for friction-free operation, while offering infinite resolution, long service life and high measurement repeatability. Units are highly resistant to shock and vibration, impervious to external magnetic fields and are designed to be compatible for use with all industry standard LVDT signal conditioners. The low mass of the Sensorex model SX9W3 core LVDT assembly makes the transducer ideal for use in applications where high-reliability displacement measurements are required, though where mass, weight and space constraints may be of concern.

Recommended accessories for the Sensorex model SX9W3 include the model SX3120 DIN rail signal conditioner for industrial applications, as well use of an MCHP conditioner for integration with electronic boards. In addition, a spare core assembly, mounting flange, and custom calibration and core assemblies are available upon request. All Sensorex model SX9W3 miniature LVDT’s are accompanied by a two-year comprehensive product warranty and are available thru both Meggitt’s San Juan Capistrano, California, USA and Archamps, France-based facilities
