Temperature sensor amplifier
The WTK-110 converts the low-voltage thermocouple signal into a standard 4–20 mA current signal. The modular housing is designed for DIN-rail mounting, and a built-in sensor compensates for ambient temperature fluctuations. Both the sensor-to-amplifier and amplifier-to-monitoring-system connections should be made with shielded cable of at least 2 × 0.2 mm²
Every amplifier in the WTK series works with a type K or J thermocouple and is compatible with the Autronica Sunderland Forge temperature transmitter. The model is equivalent to GA-110
Model WTK-110 is manufactured in versions for different temperature ranges and thermocouple types
