Heavy-duty vapor-actuated remote thermometers from NOSHOK Inc., Berea, OH, indicate media temperature using a temperature-actuated liquid in the sensing element and an accurate pressure gauge. As the media temperature increases, the capillary fill fluid vaporizes, increasing pressure in the Bourdon tube to active the movement and point in the pressure gauge. The thermometers are offered in 2.5 in., 4 in., 4.5 in., and 6 in. sizes and temperature ranges from –40°C to 60°F/°C through 100°C–350°F/°C. Applications include remote panel installations on service trucks in the oil and gas industry and temperature measurement in power transformers, paper mills, refineries, petrochemical, chemical, HVAC/R, food processing, and pharmaceutical applications.
