    Dial Type Temperature Indicators


    Mercury in Steel filled system temperature gauges in stem type and capillary type construction with 1% accuracy..from 65 to upto 200 m dial size, stem lengths upto 12 feet and capillary lengths upto 20 meters. Long capillary Thermometers with capillary compensation for better accuracy. Thermometers with electrical switching contacts for control purpose. For applications where inly indication is desired it is recommended to used dial type thermometers. These instruments contains hermetically sealed Mercury filled system. The thermometer utilizesnatural phenomenon of mercury to expand when heated. The advantage of use of mercury over any other filling medium is close to linear coefficient of expansion from -40 Deg C to 600 Deg c. The instruments are housed in weatherproof die cast Alluminium case or bayonet locking type SS 304 cases. Die Cast gauges are available in 65 mm, 100 mm, 150 mm and 200 mm dial sizes.
    Where as SS 304 case are available in 100 mm and 150 mm dial size. All stainless steel temperature gauges are best suited for use in application involving corrosive process fluid coupled with hostile and corrosive environment. These gauges are manufactured in Rigid Stem type for local reading or flexible capillary type for distant reading. Fall the instruments are provided with case temperature compensation. Gauges with long capillary are provided with capillary compensation for better accuracy.
