Temperature sensor amplifier

WTK-100

The WTK-100 converts the low-voltage thermocouple signal into a standard 4–20 mA current signal. The compact housing with a polyamide terminal block allows mounting on a TS-32 or TS-35 rail. A built-in sensor compensates for ambient temperature fluctuations, and 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-100
