Description

STAHL Safety Temperature Monitor & Limiter Series 8146/5

STAHL safety temperature monitors 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 a leak in the system. The set value can be seen from the outside through the inspection window.
