- WM261温湿度变送器
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
