TC47-AB Adjustable Bayonet Thermocouple

The WIKA TC47-AB adjustable bayonet thermocouple is a general purpose temperature sensor designed to suit all applications where metal sheathed thermocouples are required. An extensive range of elements and process connections can be individually selected for the appropriate use. With the flexibility of different diameters and manually adjustable immersion lengths, the model TC47-AB thermocouple can be used in a wide variety of easily accessible locations.

The adjustable bayonet cap allows the sensor to have a positive pressure at the tip when installing correctly.

The adjustable bayonet, tube and wire design are held in place with a bayonet adapter. They are especially suited for applications where the metal sensor tip is fitted directly into a drilled hole.

The temperature sensor can be modified to suit particular application as required.
