(Double) temperature controller and

limiter

Series 8146/5041, 8146/5051

4.1 Function

Series 8146/5041 is a temperature controller and limiter with a liquid-filled measuring

system. The change-over contact is activated due to temperature related volume

changes. In case of leakage of the measuring system, the temperature controller

switches off permanently.

Temperature controller:

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.

Temperature limiter:

If the temperature of the sensor exceeds the set value, the limiter switches off

permanently. After the temperature has dropped, the temperature limiter can be unlocked

manually.
