The TBS series bi-metal temperature switches are ideal for temperature monitoring and control applications in pipes where a simple reliable design and ease of installation are required. The TBS switch operates on the bi-metal principle. A contact mechanism of two dis-similar metals expands and contracts at different rates as process temperature changes, causing movement of the contact. The design is such that the contact separates at a pre-determined temperature setpoint. This method of temperature monitoring is widely used and results in a very repeatable temperature setpoint.

For ease of installation, the TBS is supplied in a pipe tee in brass or stainless steel, from 1/4” to 1-1/2” line sizes. The contact has a normally closed (N/C) switching function and is available in one of 18 discrete setpoints ranging from - 10°C (14°F) to 100°C (212°F).
