Bi-metal temperature switch TWR ss=eries

NONCthreaded

Overview
The KOBOLD temperature switches TWR use a bimetallic element with a snap action contact to monitor liquid temperatures in pipes and vessels. Units are available in brass (nickel plated) or stainless steel and are installed via a G ¾ screw-in thread into a welded socket. Switching points are fixed in 5 °C steps between 30 °C and 50 °C and in 10 °C steps between 50 °C and 120 °C. Contacts are available as N/C or N/O. The standard electrical connection is a plug (DIN 43 650); an optional pilot lamp can indicate switching status.

Highlights

• Easy mounting via G ¾ screw-in thread
• Position independent
• Materials: brass nickel plated or stainless steel
• Fixed switching point range: +30 °C … +120 °C
• Contact types: N/C or N/O

Applications
Monitoring of liquid temperatures in industrial piping and vessels (process control and safety applications).
