What are the advantages of _ instrument thermocouple thermometer

Thermocouple thermometer advantages have 1, high measurement precision. Because of thermocouple direct contact with the object being measured, not affected by intermediate medium. 2, wide measuring range. The commonly used thermocouple from - 50 ~ + 1600 ℃ can be continuous measurement, some special thermocouple low measurable to - 271 - + 2800 ℃ as gold iron nickel chromium and tungsten - Rhenium. 3, simple structure, easy to use. Thermocouple is usually composed of two different kinds of metal wire, but is not limited by the size and the beginning of, outside has protective casing, which are very convenient. 4, the output signal is linear good, convenient to realize industrial production process automation. Thermocouple is the temperature of the temperature measuring device is commonly used in industry, has the following characteristics: (1) high accuracy of measurement: thermocouple direct contact with the object being measured, is not affected by the medium in the middle of the. (2) thermal response time fast: thermocouple is responsive to temperature changes. (3) large measuring range: thermocouple from - 40 ~ + 1600 ℃ can be continuous temperature measurement. (4) reliable performance, good mechanical strength, long service life and easy installation. Thermocouple type thermocouple is K type nickel chrome - Nickel silicon WRN series, N type nickel chromium silicon - Nickel silicon magnesium WRM series, E nickel chrome - Copper and nickel WRE series, iron - J type WRJ series of copper nickel, copper - model T Copper and nickel WRT series, S platinum rhodium - 10 Platinum WRD series, R type platinum rhodium - 13 Platinum WRR series, B type platinum rhodium - 30 Platinum rhodium 6 WRB series and so on. The structure of thermocouple thermocouple heat is the basic structure of electrode, insulation and protection tube; And display instrument and record instrument or computer systems. According to the environment in the field use, developed into a variety of factors such as measured medium is suitable for all kinds of thermocouple. Thermocouple is divided into simple fabricated thermocouple, thermocouple and a special form of thermocouple; Segmentation by using environment with high temperature thermocouples, wear-resistant thermocouple, thermocouple, corrosion resistance to high pressure thermocouple, thermocouple, flame-proof aluminum liquid temperature with thermocouple, circulating fluidized bed with thermocouple, cement rotary kiln with thermocouple, anode baking furnace with thermocouples, high temperature hot blast stove with thermocouple, stove with thermocouples, with thermocouple carburizing furnace, high temperature salt bath furnace with thermocouple, copper, iron and steel with thermocouple, antioxidant tungsten-rhenium thermocouples, vacuum furnace with thermocouple, platinum, rhodium thermocouple, etc.
