Temperature sensor amplifier

WTK-2

The WTK-2 converts the low-voltage thermocouple signal into a 2.4–8.25 mA current signal, replicating the characteristic of the original modules used in older monitoring systems. The compact housing with screw terminals allows mounting on a TS-32 or TS-35 rail

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-2
