High Temperature CANopen Pressure Transducer HT-C-FEM-P

A high-end digital transducer for undamped dynamic pressure measurement directly at the measurement point without the need of any pressure measurement hose.

AVL Approach

This small-sized, lightweight sensor permits direct mounting at the pressure measurement point, eliminating any damping effect due to the absence of a measurement hose. It makes the exact recording of dynamic pressure signals possible.

HT-C-FEM-P pressure transducers acquire the pressures of liquid and gaseous media. The HT-C-FEM-P allows dynamic pressure monitoring and recording (up to 1,000 Hz per transducer). In addition to the internal calibration, CANopen pressure transducers support PUMA Open's semiautomatic calibration (SAC) with 16 calibration points. The values between the calibration points are determined by means of linear interpolation.

The C-FEM-P's high level of integration in AVL PUMA OpenTM ensures fast real-time processing of data transferred from the pressure transmitter to the automation system. The acquired signals are transferred in physical units to the AVL PUMA OpenTM system by means of a CANopen interface.

Typical application: Racing or drivetrain testbeds


Benefits at a Glance

  • High-end technology
  • Thanks to its small (2cm) and light (13g) design, the pressure sensor can be directly mounted at the pressure measurement point
  • Specified for ambient temperatures of up to 200°C and a shock resistance of up to 1.000g (electronic: -25°C to +85°C)
  • As no measurement hose is required, damping effects and measurement errors caused by the hose are completely eliminated
  • Fully compatible to C-FEM-P pressure measurement
