Bending/kinking or cutting the capillary of the panel-mounting thermostats will
lead to a permanent device failure!
The minimum admissible bending radius of the capillary is 5 mm.
The temperature probe must be installed in JUMO sheaths, otherwise, the
approval of the panel-mounting thermostats will become null and void.
Ensure that the temperature probe is completely submerged in the medium to
be measured. Ensure that the temperature probe or the sheath does not make
contact with the container or pipe walls.
Only use the devices in combination with the factory-supplied sheaths (d = 8
mm or d = 10 mm) to ensure the general response accuracy.
The d = 10 mm sheaths must only be used for d = 8 mm probes.
One sheath (15 x 0.75 mm) can be used for 2 or 3 cylindrical probes with a
diameter of d = 6 mm.
When using a sheath for 2 probes, fit the factory-supplied contact pressure
spring into the sheath.
For the operating medium air, select the connection type "10“ (without sheath).
For sheaths 22, 41, 42 and 45 made of material St35.8 I, the admissible ser-
vice life is limited to 200,000 operating hours at operating temperatures
exceeding +420 °C. Adhere to the TRD 508 for applications
in this range.
