Panel-mounted Thermostat

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.

Panel-mounted thermostats operate according to the fluid expansion principle

− a microswitch

is used as the electrical switching element.

Switching function

Safety temperature monitor STW (STB)

If the temperature on the temperature probe exceeds the setpoint value, the microswitch is ac-

tivated by the transmission mechanics and the electrical circuit is opened or closed. If the tem-

perature 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 un-

locked 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 dia-

phragm of the STB drops and permanently opens the electrical circuit. Unlocking is then no lon-

ger 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 dia-

gram. The circuit diagram must comply with DIN EN 50156.
