Powell Electronics has announced its availability of Honeywell's flexible and durable sensor array for heavy-duty and off-highway applications.

Now available through Powell Electronics, the supplier of connectors for high-reliability applications including defence, aerospace and industrial, is the Transportation Attitude Reference System (TARS) from Honeywell. TARS is a packaged sensor array designed to report vehicle angular rate, acceleration, and attitude data for demanding applications such as heavy duty and off-highway transportation.

The TARS-IMU device measures important vehicle characteristics and enhances efficiency and productivity by reporting key data required to automate and monitor movements of vehicle systems and components. With two sensor models for different power levels, the TARS-IMU sensor array accommodates both 5V and 9V to 36V vehicle power systems.

The sensor fusion algorithm can be customised for specific vehicle applications via on-board firmware, allowing movement data to be filtered to minimise unwanted noise and vibrations for improved position accuracy. Communication is transmitted using industry standard CAN J1939 connectivity. As a standard, the TARS-IMU component is calibrated on aerospace-grade rate tables at the factory to provide enhanced calibration consistency between units.

The operating temperature range is −40°C to +85°C. The TARS-IMU sensor array comes in a ruggedised PBT thermoplastic housing and is IP67 and IP69K certified for use in the most demanding environments. A metal guard for added protection is also available.
