Brief description

The explosion-proof surface-mounted thermostats of the JUMO exTHERM series are built to

monitor and control temperatures in potentially explosive areas. The use in environments with

gas and steam is permitted (zones 1 and 2); use in environments with conductive dust (zones

21 and 22) is also permitted.

The JUMO exTHERM-AT is available as temperature monitor TW, safety temperature monitor

(STW), and safety temperature limiter (STB). The thermostats work according to the liquid ex-

pansion or gas expansion principle. The electrical switching element is a pressure-resistant en-

capsulated thermostat with a snap-action switch. Stable switching points when ambient

temperatures fluctuate are made possible by the standard ambient temperature compensation.

The thermostats of the JUMO exTHERM-AT series are RoHS conform and cadmium free.

Version according to DIN EN 14597:

TW Temperature monitor

STW Safety temperature monitor

STB Safety temperature limiter
