BW - Wall mounted

Heavy-duty transmitters for advanced requirements

Features

  • Operating temp up to 200 °C
  • Accuracy H.: ±1.5 % RH
  • Accuracy T.: ± 0.15 K with analogue output
  • Accuracy T.: ± 0.2 K with modbus
  • On-site calibration

  • Modbus

Our Heavy-duty transmitter wall mounted BW can be used at temperatures between -40 °C and 85 °C.
The integrated hx processor can calculate further humidity values and apply them to the two outputs. With the RS485 standard all of the hx-values can be read simultaneously.

Capacitive MELA® sensorchips
Equipped with the highly dynamic capacitive MELA® sensor element, the sensor provides reliable performance across the full humidity range. Using the MELA® sensor element ensures long-term stability, resistance to dew formation, minimal hysteresis, and strong dynamic capabilities.
