Spring Loaded Thermocouple Inserts

Product Code: TSL

The TSL spring loaded, mineral insulated, metal sheathed thermocouple inserts are designed to suit new or existing heavy-duty thermowells. Most commonly supplied with a 6.0mm outside probe diameter (3.0mm, 4.5mm and 8.0mm also available).

A ceramic terminal block is supplied as standard and can be connected to a terminal head using the spring loaded screws. An optional 4~20mA transmitter can be supplied instead of the ceramic terminal block, if required.

Spring loading ensures that the sensor tip is kept in contact with the tip of the thermowell, which promotes a faster and more reliable response.
