Pressure transmitter 540
The microprocessor-controlled, programmable pressure transmitters of Type 540 feature a robust industrial design. Through a configuration menu with up to two programmable switching points, the parameters can be easily adjusted using two user-friendly function buttons. All devices have a diagnostic function. The large 4-digit LED display ensures good readability. The 540 pressure transmitters are based on the thick-film technology developed by Huba Control, in which the pressure measuring cell is welded to the pressure receiver without seals.
- Compact and robust design
- High overpressure safety
- Easily readable display
- Simple operation
- Diagnostic options
- Available with analog signal
- With up to two programmable switching outputs
