The WM-Sensor series provides the best high accuracy and great temperature
stability for room comfort, and it is dedicated to wall mounted applications. They
convert the measured values into linear 4 to 20 mA signals and optional 0 to 10
Vdc output can also be offered under request. The microprocessor based circuit
enables full configuration of output range when used with the TxConfig PC
interface and the Windows® based software.
Features and Specifications:
- Accuracy: 0.5 °C @ 25 °C
- Repetibility: ±0.1 °C
- Range: programmable between -50 and 120 °C
(please check operational limits)
- Response Time: up to 30s in fairly still air
- Operational limits: 20 to +65 °C, 0 to 95% RH
Note: When measuring temperatures higher than +65
°C or lower than -20 °C, only 50% of the probe total length must be inserted
into the measured environment
