Kobold TWR Temperature Switch

Kobold TWR Temperature Switch with Fixed Switching Point

The Kobold TWR range of temperature switches work with a bi-metal switch and serve to monitor temperature of liquids in piping and vessels. The TWR instruments are available in brass or stainless steel and have G ¾”/3/4″BSP screw-in thread into a screwed socket that is welded onto the line or vessel.

The temperature contacts have a fixed switch point in intervals of 5 °C in the range 30 °C … 50 °C, and in intervals of 10 °C between 50 °C and 120 °C. They are available as N/C or N/O contacts. Standard electrical connection is made through a plug connector, in which a pilot lamp can be integrated as an additional output state indicator.
