TEMPERATURE GAUGES
1. Mercury/Gas Filled Temperature Gauges
Mercury / Gas filled temperature gauges are economical, rugged, reliable and accurate measuring instruments. Made of bulb, transmitting capillary and flat bourdon or coiled bourdon tube which are pressure filled with Mercury / Inert Gas. The system is pressurized with mercury / inert gas. Variation of the ambient temperature are compensated by means of a Bi-Metal link between movement mechanism & Bourdon Tube.
