Monitoring with electronic safety temperature limiters/monitors and electromechanical thermostats
Electronic temperature monitoring is vital in many applications. In particular when it involves safety-related temperature monitoring of special system equipment which can pose an enormous hazard to people, the environment, the product, and production system when defined limit values are not observed. With the safetyM product line we offer sophisticated electronic temperature limiters/monitors to avoid such hazards. The advantage of SIL-certified devices: in case the plant’s defined maximum or minimum temperature is exceeded or not reached, the electronics ensure that the plant is shut down with the utmost precision.
In applications where no auxiliary energy can be supplied to power the electronics, the electromechanical thermostats reliably perform their tasks and therefore play a crucial role in ensuring a safe production plant or equipment design. The thermostats operate according to the liquid expansion principle: the liquids in the measuring system expand when heated and transmission mechanics activate a microswitch which then safely shuts down the system.
