General information
CAUTION!
Failure of the device
Cutting through or kinking the capillary will lead to permanent failure of the device!
Minimum permissible bending radius of the capillary is 5 mm.
The temperature probe must be fitted in a JUMO thermowell, otherwise the approval of the device ex-
pires.
NOTE!
The temperatur probe must be completely submerged in the medium.
In order to ensure the general accuracy of response, the devices must only be used with the thermowells
supplied from the factory (diameter D = 8 or 10 mm).
Only probes with a diameter D = 8 mm may be fitted in thermowells with a diameter D = 10 mm.
When the operating medium is air, connection type „10“ (without thermowell) must be selected.
