When mounting a rotatable and inclinable gas-actuated thermometer, specific
instructions must be followed. In order to set the indicator to the desired
position, the following steps must be taken:
1. The lock nut or union nut must be loosened at the process connection.
2. The hexagon bolts and slotted screws at the swivel joint must be loosened.
3. Position the indicator as required, tighten the hexagon bolts and slotted
screws, and finally tighten the lock nut or union nut firmly.
T If a thermowell is used, the stem must not be allowed to touch the bottom of
the thermowell.
T Capillaries must be kink protected. The minimum bending radius for
capillaries should not be less than 6 mm. Any kinks or discontinuities in the
capillary may result in the failure of the instrument.
T If the probe is installed in a location which is exposed to shock and vibration,
it is essential that the capillary is coiled in several loops, and free of tension
between the last attachment point and the probe. Any excess length should
also be coiled into loops, as cutting the cable would make the instrument
unserviceable.
T Any welding or soldering of the capillary, as well as any permanent fastening
of the capillary, must be avoided, as this can severely damage the capillary,
and impair the operation of the instrument.
