TEMPERATURE GAUGES ....
1) GENERAL PURPOSE DIAL TYPE THERMOMETERS
"OSMADIAL
/ SCIECON" Mercury in Steel General
Purpose temperature gauges are basically designed
to measure the temperature, which operate on the principal
of change of shape of boudens tube on account of internal
pressure variation due to change in volume of mercury
inside the sensor probe caused by the temperature.

2) COMPENSATED SYSTEM TYPE TEMPERATURE GAUGES
"OSMADIAL
/ SCIECON", Mercury Filled FULLY
COMPENSATION TYPE dial thermometers is used in
Chemical reactors of Chemical, Dyestuff, Sugar, Food &
Fertilizer Industries.
The object of the thermometer is to detect changes of
the temperature at the bulb. There is however, the possibility
of error caused by variation of temperature along the
tubing or at the pressure spring itself. In long system
where the length of the capillary or tubing is more then
2 mtr, the volume of the tubing may be great enough to
allow temperature changes along the tubing.
Now, Fully Compensated systems employ a second pressure
spring and tubing. By means of linkages, the motion of
the compensating pressure is made equal and opposite to
the motion of the primary pressure spring. If the temperature
along the primary tubings varies, causing expansion of
the primary spring, the expansion of the compensating
spring due to the same variation acts to cancel out the
resulting motion of the indicating mechanism and thereby
showing the actual mechanism.
