The Type 2213 Safety Temperature Monitor
(STM) with a valve operates without auxilia-
ry energy and is designed for extended safe-
ty according to DIN EN 14597. The valve is
closed by a spring mechanism when the tem-
perature reaches the adjusted limit, when the
capillary tube breaks or when leakage oc-
curs in the sensor system. The devices are
automatically reset and put back into opera-
tion after the temperature has fallen below
the limit and the fault has been remedied.
When the safety temperature monitor is com-
bined with a Type 2231 to 2235 Control
Thermostat, make sure that there is a mini-
mum difference of approximately 15 K be
-
tween the adjusted limit temperature of the
safety temperature monitor and the set point
temperature of the control thermostat.

perature Monitor as well as the Types 2111,
2422, 2118 and 2119 Valves. The lengths

Typetesting
The safety temperature monitor is tested by
the German Technical Inspectorate (TÜV) ac
-
cording to DIN EN 14597 under the type
designation 2213. The registration number
is available on request.
