管道式温湿度变送器WM261

   The WM261 transmitter performs measurement, conversion, and analogue transmission of relative humidity and temperature. These two parameters are transmitted to remote receivers via an analogue signal. WM261 transmitters have a sensor/converter.

Product Features

  • Scale configurable on request: 0–50°C, 0–100°C, -20 to +80°C,
    -30 to +20°C, -30 to +70°C
  • Output signal configurable on request: current/voltage depending on version
  • Humidity output signal linearised and compensated from 0 to 60°C via digital processing
  • On request, linearisation for a specific isotherm
