Description

In the event of any faults, the safety temperature limiter model SB15 puts the system into a safe operating condition.

The shifting disk, which is arranged on the pointer shaft, actuates the switching operation at the micro switch when reaching the non-adjustable switch point or in case of measuring line breakage and locks the current status.

A reset is possible with a tool only after a temperature decrease by approx. 3 % of the scale range, if there is no measuring line breakage.
