TWR – Temperature Switch for Liquids

The KOBOLD TWR temperature switch for liquids is used to provide thermally triggered switching functions for liquids in pipe systems and tanks. Individually, it can provide temperature alarm features to ensure process compliance with maximum or minimum limits, for example. In pairs, this temperature switch can provide wide hysteresis (deadband) thermostatic control function to control heating and cooling equipment. The TWR is available in brass or stainless steel and has a 3/4″ NPT fitting for direct installation into pipes or tanks. The switch operates at a preset switch point, which is factory-set in 9°F increments between 86°F and 122°F and in 18°F increments between 122°F and 248°F. The contacts are available in normally open (N/O) or normally closed (N/C) configurations. Electrical connection to the TWR is achieved via a DIN 43 650 plug, which is optionally available with an integrated signal lamp, providing a visual indication of switch condition.
