Meggitt Sensing Systems announces North American debut of MEMS triaxial inertial measurement unit with integral digital compensation

Meggitt Sensing Systems, a Meggitt group division, has announced the North American market debut of the Sensorex model SX43040, a rugged, high-performance MEMS triaxial inertial measurement unit (IMU) with integral digital hybrid compensation, designed to provide current rate of acceleration, gravitational force and degree of freedom (DOF) measurements, including changes in roll, pitch and yaw, across three orthogonal axes.

The Sensorex model SX43040 is both lightweight and compact and incorporates MEMS technology with no moving parts, ensuring high-reliability performance within extreme environments. With available measurement ranges from 2 g to 10 g and angular speed ranges from 50&deg;/s to 1500&deg;/s, the model SX43040's integral digital hybrid compensation (DHC) module allows the IMU to achieve a very high accuracy of <&plusmn;0.9% FS (gyro <&plusmn;0.1% FS) after self-compensation of non-linearity, temperature drift, bias and misalignment errors. Bandwidth is fully user adjustable over a range of 0.1 to 100 Hz (-3 dB). Several outputs are simultaneously available, including digital RS485 Modbus RTU, &plusmn;5 V analog output and autotest pin, with setup parameters established via the digital interface. The Sensorex model 43040 is designed to reliably operate over a temperature range of -40&deg;C to +75&deg;C (-40&deg;F to +167&deg;F) with a built-in self-test feature on all three axes, ensuring added measurement reliability. In addition, all Sensorex model SX43040 IMU'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.

With its high-accuracy measurement capabilities, the Sensorex SX43040 is ideal for use a number of testing and on-board applications, such as flight test, road and rail vehicle behavioral studies, control and stabilization, flight control and navigational back-up on aircraft or watercraft, or in any application where rate of acceleration or gravitational force measurements may be required to a high degree of accuracy.
