Description
Dial thermometers with microswitches are universal temperature controllers with an actual value display
for temperature measurement, control, and monitoring.
The temperature-dependent volume change in a measuring system filled with liquid, or the temperature-
dependent pressure change in a measuring system filled with gas, is converted to a rotational movement
of the actual value indicator by a bourdon tube; no transmission gear is required. The microswitch is ac-
tuated by the rotational movement of the indicator shaft via a tap system.
Series 608530 dial thermometers with microswitches are RoHS-compliant and cadmium-free.
