C-FEM-P_TI

CANopen Pressure Transducer C-FEM-P

A high-end digital transducer for precise pressure measurement in automotive engine and powertrain testing.

AVL Approach

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.

C-FEM-P pressure transducers acquire pressures of liquid and gaseous media. The 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.


Benefits at a Glance

  • High precision recording of very dynamic pressure curves due to high speed data acquisition of up to 1,000 Hz
  • Real-time data synchronization with the AVL PUMA OpenTM testbed automation system
  • Reduction of testbed downtime by means of automatic zero offset calibration
  • High comfort for the operator due to automatic sensor detection and automatic addressing (daisy-chain technology)
