pSENS MH-4, type MH-4-CAN

Robust CAN pressure sensor of the latest generation

Focus on reliability and precision

The MH-4-CAN is characterized by its particular reliability over its entire life cycle. It withstands dust, moisture, heat and mechanical stress and is therefore ideally suited for mobile use. The maintenance-free device design contributes to a low total cost of ownership. Even after more than 100 million load cycles, the sensor's long-term drift is less than 0.1% FS.

  • Extreme operating conditions
  • Signal stability thanks to CANopen®
  • Reliable and precise measurements
  • Customer-specific adaptions
  • High production capacities

Product Description

Powerful and robust

The MH-4-CAN is an extremely powerful and reliable pressure sensor designed specifically for use in mobile machinery. No matter how demanding the conditions, this sensor always delivers precise measurement data and ensures high operational reliability. Thanks to its outstanding performance, the MH-4-CAN is able to deliver reliable results even under extreme environmental conditions.

Serial interface for complex machines

The special feature of the MH-4-CAN is its serial interface, either CANopen® or SAE J1939. This allows the sensor to be used in complex machines and offers the advantage of simple and cost-effective system expansion. Even over long distances, signal stability and integrity are maintained and reliable communication is ensured.

High reliability over the entire life cycle

The MH-4-CAN was specially developed for the specific requirements in mobile working machines and meets the highest demands. It is able to perform precise measurements at temperatures from -40 to +100 °C and withstands pressure peaks of up to 3 times the overpressure limit. Optionally, the sensor is also available with choke. Thanks to its metallic shielding, the MH-4-CAN is insensitive to electromagnetic interference of up to 60 V/m. In addition, vibrations up to 40 g and shocks up to 100 g do not affect the measurement quality of the sensor.
