A
Cutting through or kinking the capillary of the panel-mounting thermostat will
lead to permanent instrument failure!
Minimum permissible bending radius of the capillary is 5 mm.
The temperature probe must be mounted in a JUMO pocket, otherwise the
approval of the panel-mounting thermostat becomes invalid.
The temperature probe must be completely immersed in the medium to be
measured. The temperature probe or protection tube must not come into
contact with the walls of the container or pipe.
To ensure their overall accuracy, the thermostats must only be used together
with the pockets supplied by the factory (diameter D = 8 or D = 10 mm).
Pockets with diameter D = 10 mm may only be fitted with probes with
diameter d = 8 mm.
Fitting several probes into a common pocket is permissible with 2 or 3
cylindrical probes with diameter D = 6 mm and pockets 15 x 0.75 mm.
When fitting 2 probes in a common pocket, the factory-supplied spring clip
must be fitted in the pocket.
For operation in air, probe mounting type “10” (without pocket) must be
chosen.
In the case of pockets 22, 41, 42 and 45, in materials St35.8 I, the permissible
operating life at operating temperatures above +420°C is limited to 200,000
hours. The requirements of TRD 508 must be observed for operation in this
range.
