Mercury Filled Temperature Gauges
'MASS' make mercury filled temperature gauges are made of a sensor bulb, transmitting capillary and a special flat bourdon tube, which are pressure-filled with mercury. As temperature changes the bulb will change the pressure in the system and indicated on the scale, calibrated in temperature units. A Bi-metal device is connected to the bourdon tube to compensate for temperature error due to variation in ambient temperature. Mercury filled temperature gauges measures from 38C to 600C with an accuracy class of+1% of full scale.

'MASS' make mercury filled gauges are economical, rugged, reliable and accurate measuring instruments available in different dial sizes, connection, mounting with different type of capillary with different length (maximum up to 25m). Mercury filled temperature gauges are also available with accessories like Antivibration spring, Electrical contact, Gauges with Glycerin or Silicon oil filled and with thermowells.

'MASS' mercury filled temperature gauges are widely used in Ovens, Furnaces, Vessels, Pulp and paper industries,
Chemicals, Petrochemicals, Fertilizers and Refineries, Smelters & Foundries.
