KOBOLD Instruments, Inc. TWR - Temperature Switch for Liquids

Product Features Simple Installation Position Independent Ni-Plated Brass or SS Construction Optional Signal Lamp Maximum Temperature 248°F KOBOLD's 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 TWR's can be chosen to provide wide hysteresis (deadband) thermostatic control function to control heating and cooling equipment. The TWR is available in brass or stainless steel and has 3/4†NPT fitting for direct installation into pipes or tanks. The switch operates at a preset switchpoint. The switchpoint is factory set, but selectable in 9°F increments between 86°F and 122°F and 18°F increments between 122°F and 248°F. The contacts are available in normally open (N/O) and normally closed (N/C) configurations. Electrical connection to the TWR is achieved via a DIN 43 650 plug. The plug is optionally available with an integrated signal lamp, providing a visual indication of switch condition.
