Safety temperature monitor
STW If the probe line falls below the entered setpoint value over a length of 15 cm with 3 m, 30 cm with 6 m, and
40 cm with 12 m, then electrical circuit 1-2 is opened while electrical circuit 1-4 is closed due to the change-
over function. When the temperature rises, the microswitch is automatically switched back to its original posi-
tion.
If the measuring system is destroyed (i.e. if the expansion fluid escapes) the pressure in the diaphragm drops
and permanently opens electrical circuit 1-2 and closes electrical circuit 1-4.
Safety temperature limiter
STB In the event of a temperature drop, the safety temperature limiter automatically locks and can only be
unlocked manually once the temperature has risen again.
If the measuring system is destroyed (i.e. if the expansion fluid escapes), the pressure in the diaphragm drops
and permanently opens electrical circuit 1-2 and closes electrical circuit 1-4.
Type 5 Type 7
Case Case bottom section: PA (reinforced)
Color: Silver gray RAL 7001
Case lid: ABS with inspection window (PMMA)
Color: Cobalt blue RAL 5013
Setpoint value adjustment
STW, STB The switching point can be adjusted with a screw-
driver once the case lid has been removed. The set
switching point can be checked through the inspec-
tion glass.
Switching point can adjusted with a screwdriver.
