Train Measurement System
TMS-E232

Description:
Designed specifically with the rail industry in mind, the Train Measurement System (TMS) features an extensive sensor suite inside of an extremely rugged package. With two angular rate sensors and a single axis accelerometer, the TMS is an ideal choice for any application measuring, roll, yaw, superelevation, truck hunting, or track irregularities.
One of the cornerstones of the TMS is its rugged design. The gyros used in this package are isolated from vibration internally, and the sensor inputs are processed by an on-board microprocessor. This allows the TMS to be mounted directly to the truck underneath a rail car or locomotive. The durable enclosure that houses the TMS electronics is designed to allow for mounting in such a demanding environment.
Applications:
The TMS-E232 is used in the rail industry for track testing and high speed train tilt testing. This sensor is also useful on vehicles when the required mounting location is in an extremely harsh environment.
