Panel-mounted Thermostat

DGRL

97/23/EG

EM Series

Special features

• Safety temperature monitor STW (STB)

• Safety temperature limiter STB

• Tested according to DIN EN 14597 and the Pressure Equipment Directive 97/23/EC

Brief description

Panel-mounted thermostats are used to monitor thermal processes. The devices are available
as safety temperature monitor STW (STB) and safety temperature limiter STB. In the event of a
malfunction, the STB switches the monitored machine to a safe operating status.

Data Sheet 602026

Page 1/7

Panel-mounted thermostats operate according to the fluid expansion principle
is used as the electrical switching element.

− a microswitch

Switching function

Safety temperature monitor STW (STB)

If the temperature on the temperature probe exceeds the setpoint value, the microswitch is ac­tivated by the transmission mechanics and the electrical circuit is opened or closed. If the tem­perature falls below the selected setpoint (by the amount of the switching differential), the
microswitch is reset to its initial position.

Restart lock of the safety temperature limiter STB

If the temperature on the temperature probe exceeds the set limit value, the electrical circuit is
opened and the microswitch is mechanically locked. The microswitch can be manually un­locked once the temperature has dropped by approx. 10 °C.

Self-monitoring for the safety temperature limiter STB
and safety temperature monitor STW (STB)

If the measuring system is destroyed (i.e. if the expansion fluid leaks), the pressure in the dia­phragm of the STB drops and permanently opens the electrical circuit. Unlocking is then no lon­ger possible. When the probe has cooled down to a temperature below approx. -20 °C, the
electrical circuit is also opened. However, it automatically closes again when the temperature
rises.

Use of the safety temperature monitor STW
as a safety temperature limiter STB

The activation lock required by DIN EN 14597 must be warranted by the following circuit dia­gram. The circuit diagram must comply with DIN EN 50156.

If changes occur to the

relation to the calibration
ambient temperature
(= 22 °C), a switching point
deviation occurs. For highly
fluctuating ambient tempera­tures, we recommend the use
of thermostats with tempera­ture compensation (extra
