What is the contact temperature sensor?

Temperature sensor is a variety of sensors in a variety of commonly used one,Modern temperature sensor shape is very small,So that it is more widely used in various fields of production practice,But also for our lives provides numerous convenience and functionality.

Contact temperature sensor classification:
Metal expansion principle design of the sensor,
Contact temperature sensor,
Resistance sensors,
Thermocouple sensor

        Thermometer is an application of contact temperature sensor,The thermometer achieves thermal equilibrium by conduction or convection,So that the thermometer's indication can directly indicate the temperature of the measured object.General measurement accuracy is higher.In a certain temperature range,The thermometer also measures the temperature distribution inside the object.But for the moving body,Small targets or very small heat capacity of the object will produce a larger measurement error,Commonly used thermometer with bimetallic thermometer,Glass liquid thermometer,Pressure thermometer,Resistance thermometer,Thermocouple and thermocouple.
        With the low temperature technology in the defense engineering, space technology, metallurgy, electronics, food, medicine and petrochemicals and other sectors of the extensive application and superconducting technology research,Temperature below 120K measured temperature of the thermometer has been developed,Such as cryogenic gas thermometers,Vapor pressure thermometer,Acoustic thermometer, paramagnetic salt thermometer, quantum thermometer,Low-temperature thermal resistance and low temperature thermocouple and so on.Low-temperature thermometer requires a small temperature sensing element,High accuracy, good stability.The use of porous silica glass sintered carburized glass thermal resistance is a low temperature thermometer temperature sensing element,Can be used to measure the temperature range of 1.6 ~ 300K.They are widely used in industrial, agricultural, commercial and other sectors.People often use these thermometers in their daily lives.
