Safety temperature monitor Highlights - Disconnection in the event that a user-defined temperature is exceeded or fallen below, switching capacity up to 25 A Permanent disconnection in the event of leak in the liquid-filled measuring system Standardised versions available in Series 8146 Ex e enclosure. Customised solutions available on request. Functional Description - R. STAHL temperature controllers and limiters perform various tasks: They disconnect the system after an adjustable limit value is exceeded, whereby limiters remain disconnected, while controllers switch back on again when the permissible temperature is reached. Both switch off in the event of leak in the system. The set value can be seen from the outside through the inspection window. If the temperature of the sensor exceeds the set value, the controller switches off. If the temperature falls below the set value, the controller switches on automatically.
