The Kobold TWR temperature switch is used to provide thermally triggered switching functions for liquids in pipe systems and tanks. Individually it can provide temperature alarm features to, for example, insure process compliance with maximum or minimum limits. Pairs of Kobold TWR's can be chosen to provide wide hysteresis (deadband) thermostatic control function to control heating and cooling equipment.

The Kobold TWR temperature switch's contact operates at a preset switch point. The switchpoint is factory set, but selectable in 5°C increments between 30°C and 50°C and 10°C increments between 50°C and 120°C. The contacts are available in normally open (N/O) and normally closed (N/C) configurations.

Electrical connection to the TWR is achieved via a NEMA 4 plug. The plug is optionally available with an integrated LED signal light. This gives visual indication of switch condition. The Kobold TWR is available in brass or stainless steel and has 3/4" NPT fittings for direct installation into pipes or reservoirs.
