The Columbia Model SA-528RHT Force Balance Accelerometer is designed for extreme high temperature environments including aircraft engines. The Model SA-528RHT is capable of operating at temperatures of up to 175 degrees Celsius. This sensor is completely self-contained and provides a high level, low impedance output eliminating the need for high temperature signal conditioning.

In addition to small size and exceptional high temperature performance, Model SA-528RHT incorporates our patented high performance torquer system, which provides exceptional performance and reliability in severe vibration and shock environments. An optional integrated high temperature.
