TEMPERATURE GAUGES
Temperature is probably the
most widely measured and frequently controlled variable in the numerous processes. This is because quite often processing and manufacture of the
desired product is possible only if temperatures are accurately measured.
The temperature gauges are based on the change in the physical properties,
which is simple thermal expansion due to temperature SHREEJI makes the following
two types of thermometers
1] MERCURY IN STEEL type thermometer
2] B-METALLIC type thermometer
It is one of the most versatile and widely used devices in industrial temperature measurements
The entire assembly of bulb, capillary, and gauge is calibrated directly on the basis of pressure
change changes corresponding to temperature

SHREEJI makes these temperature gauges with Electric Contact, Glycerin Filled, Antivibration Spring System etc. as per requirements of the user
This type temperature gauge employs the principle of solid
expansion and it consists of a bimetal strip. In response to the
temperature change, the bimetal expands and helical bimetal
rotates at its free ends. thus turning to pointer to a new position
on the dial SHREEJI makes these type gauges with the
following specification

In RTD the change in resistance of various materials, which various in a reproducible
manner with temperature, forms the basis of the important sensing technique. The RTD
is very suitable for both laboratory and industrial applications, because of their high
degree of accuracy as well as long term stability. The sensor of RTD is commonly made from
platinum material.
SHREEJI manufacturing different types of RTD's in different sheath metals, for various applications
Sensor Element : Pt50, Pt100, Pt1000, Cu53, Cu2000 etc.
Type : Simplex, Duplex.
Accuracy : as per DIN, BS, & JIS std.
Sheath Material : SS 316, SS 304, Brass, MS, titanium, etc.
Sheath OD : 2.5mm to 16mm
In MI Cable : 1.5mm to 8mm
Enclosure : Die -cast Aluminium Weather Proof, Die-Cast Alu., Flame Proof
The basic principle of temperature measurement using a thermocouple sensor was discovered by See back in 1821
The T/C consist of 2 wires of different metals welded together with each wire covered with insulation which may be either
1) Mineral Insulation for normal duty
2) Ceramic Insulation for heavy duty
SHREEJI makes T/C with measuring junction as grounded, exposed for quick response and ungrounded junction for isolation purposes
