Instrumentation for High Temperature Environments

Accelerometers and pressure sensors for demanding measurement & monitoring requirements

IMI Sensors is a global supplier of high temperature instrumentation. Often used in demanding industrial environments, these accelerometers and pressure sensors provide critical data that prevents failures and reduces downtime.

Our high temperature accelerometers with internal electronics (ICP®) have the best temperature capability of any design on the market today. The high temperature ICP® accelerometers are capable of withstanding continuous temperatures of 325 °F (162 °C). For applications that exceed those temperatures, IMI Sensors has a variety of charge accelerometers with integral ICP® amplifier that can operate at 900 °F (482 °C) and charge mode accelerometers that can operate at 1200 °F (649 °C).

Our high temperature pressure sensors are designed for operation at the highest temperatures. They detect and measure dynamic pressure phenomena in environments with a continuous temperature of 1200 ºF (649 ºC).

Many of the 900 ºF (482 ºC) and 1200 ºF (649 ºC) sensors (Models EX600B1X, 357A100, 357D9X, EX611AX0, 176MXX and 176AXX) feature a UHT-12™ element. The new UHT-12™ crystal technology features:

  • Absence of pyroelectric noise spikes up to 900 ºF (482 ºC).
  • Sensitivity that remains more consistent over a wide temperature change.
  • Shear mode crystals isolated from base strain & transverse measurement errors.
  • No oxygen depletion at high temperatures, thereby not requiring a housing vent or window.

Our charge amplifiers are designed to convert the high impedance signal of a charge accelerometer or pressure sensor without integral signal conditioning circuits to a low-impedance voltage signal for transmission and data collection. Differential charge amplifiers should be paired with charge accelerometers and pressure sensors with a differential output (measurement output as a plus and minus signal) to convert the differential output into a single-ended output (measurement output as a signal and ground).
