Panel-mounted thermostats 602010
ETH series
Panel-mounted thermostats from the ETH series monitor thermal processes. The devices are available as safety temperature monitors (STW) and safety temperature limiters (STB). In the event of a malfunction the STB places the system being monitored in a safe operating status.

Temperature limiter/monitor
The JUMO safetyM TB/TW is a user programmable limiter/monitor. The universal measurement input is user configurable for RTD temperature probes, thermocouples, and current or voltage signals. TB/TWs are used to monitor thermal processes in plants for a set limit value.
