Electronic safety temperature limit switches »Made in Germany« with 2 years warranty

Electronic safety temperature limit switches »SGW«, »SGT« or »SGI«

The areas of application for safety temperature limiters SGT or SGW are wherever thermal processes need to be monitored, and where the system must be set to a safe condition in the event of a fault.
If the permitted temperature limit is reached or a fault occurs within the permitted temperature range then the instrument switches off.
