1. General :
In the pressure measurement, the end of the sensing element is displaced when
tho messuod pressure is applied, In the temperature measurement, the end af the
. ‘Sensing element is displaced as mercury expands or contracts in accordance with
- Reasured temperature, The displacement jg transmitied through the Links, levers,
‘and precision segment Gears and pinjons to the pointer Which indicates the pracess
‘Yelue for a wide Seale angle of 270 degrees. At the same time, the displacement
is transmitted to the devistlon mechanism, where the displacement (which represent
the process value) is compared with respect to the setpoint value and’the resultant
Aeviatlon signal mechanieal movervent) is fed lo the controller assembly.

2. Sensing and Indicating Mechanism
Displacement of the sensing element ( #) is transmitted through the over-travel
link to the segment gear and the pinion, which magnifies the displacement angle( 0)
by a factor of 9. ‘The pointer is deflected by the pinion gear for e wide angle of
210 degrees on the scala and, therefore, reading can be made most easily.

And the automatic reset mechanism.
‘The flapper is moved towards or away from the nozzle in response to the
deviation value and the back pressure of the noztie is apple to the pilot

A portion of the controller output is fed back to the prapartional bellows

‘Adjustment of the proportional band is made by turning the proportional
Band dist. When this dial is turned, the angle of the rod is varied and,
therefore, the foodback rate is varied. The changing between direct

2) Bulb location
‘The best location for the bulb depends upon various factors, Including the
measured fluid, the fittings, the type of bulb, and the connecting tabiag.
General recommendations are listod below:
(1) Liquid temperature
‘The efficient operation of the thermal system depends on the zate at
< Which changes in temperature of the measured fluid are fole by the
bulb, Ir the bulb is located ia a thermal dead spot, the instrument
‘will bo lacking in sensitivity or will have excessive lag. ‘Therafore
‘Select a location where tho bulb will be exposed to agitated fluids of
freely flowing liquids.
(2) Gas and air temperature measurement
‘Again avoid thermal dead spots. Locate the bulb 0 that it will be in
the freely flowing stream and aot in the dead layer on the insice wall
surface of the oven, pipe, or duet. Mount the bulb at right angles 12

-2-CALIBRATION
1, General
A calibration is required whenever the units are disassembled ox replaced,
lor the messing range is changed. The measuring vange ls determined by the ~
Sensing eloment.
a) setup =~
(1) Apply 1.4 kg/om? of supply alr to the inctzument.
(2) Connect a mereury manometer or equivalent, to the controller out~
pul pert, The manometer should be readable to minimum of t malls.
(9) Provide the means to apply a pressuse or temperature manually
‘equivalent to the actual process variable tothe sensing elements.)
Note: In case, to vary a pressure or tomporature manually is
Snadequate, alfbeate az follows. Detach the over-travel
