Detect system failures and errors to avoid dangerous operation

In machine control systems for cranes, lifting platforms and forklift trucks among others pressure transmitters are typically used. By the use of two pressure transmitters mounted on the main hydraulic cylinder system, redundancy is created in the system. The transmitter detects system failures and random error functions so that moving parts are shut down in case of dangerous operation and serious accidents are avoided.

Typical specifications

  • Pressure range: 40 – 500 bar
  • Temperature range: -40 – 125 °C
  • Accuracy: 0.5% FS
  • Response time typically < 1 mS
  • Overpressure: 3 x FS
  • Burst pressure: 10 – 20 x FS
