Mercury Filled Thermometer, Temperature Gauges, Thermocouple, Resistance Temperature Detector

Temperature reflects the momentous thermal condition of a homogenous material. Measurement of temperature normally requires close, direct contact between the material and the sensor in such a manner that the sensor responds quickly to the temperature of the material.

Mercury Filled Thermometer


It is one of the most versatile and widely used devices in industrial temperature measurements. These thermometers enable measurement of temperature with an accuracy of +1% of the maximum scale value. This kind of thermometer system comprises a sensor bulb, transmitting capillary and a case containing a Bourdon Tube element. The system is filled with pressurized mercury. Temperature variation is measured by the Bourdon Tube system, and indicated on a dial.
