Provide PF4/5 differential pressure, humidity and temperature transmitter operation instructions
The document serves as a comprehensive user guide for the Rotronic PF4 and PF5 transmitter series. It details the device's capabilities in monitoring volumetric flows and pressures within ventilation and air conditioning systems. The manual explains various configurations available, including options for differential pressure, humidity (HC2), and temperature (Pt100) sensing. This manual is written in German.
| Tube inner diameter | 4 mm |
|---|---|
| Minimum supply voltage | 50 VDC |
| Cable outer diameter | 6 to 7 mm |
| Wire gauge | 18 AWG |
| Maximum cable resistance | 500 Ω |
The device features high measurement accuracy, long-term stability, a short response time, and low hysteresis.
PF4 uses a flow-based differential pressure sensor, while PF5 uses a membrane differential pressure sensor.
