Temperature calibration and Solutions

What is "temperature calibration"? Temperature calibration means any relevant equipment used in the calibration of temperature measurements One of the most important is usually the calibration of the temperature sensor Temperature sensors are usually platinum resistance thermometers (PRT or PT-100), thermistors or thermocouples The thermometers measure the output signals of these thermometers and convert them to temperature according to ITS-90 The usual way to calibrate a thermometer is to place the sensor in a stable temperature environment (usually called a heat source) and compare its output with a calibrated "reference thermometer" or "standard thermometer" Fluke metrology calibration provides three types of heat sources: heat sources for field use, such as dry type temperature calibrators (dry-type metrology furnaces), micro thermostats, etc.; liquid thermostats and thermocouples for laboratory use; and fixed point devices for calibrating standard platinum resistance thermometers Fluke metrology and calibration department also provides a variety of reference level thermometers (such as standard platinum resistance thermometers) and high accuracy thermometers In addition, fluke metrology and calibration department also provides various laboratory and field solutions for the calibration of electronic devices used in temperature measurement systems Calibration of field, laboratory and temperature based standards field temperature calibration (or "industrial" or "portable" temperature calibration) is suitable for temperature test calibration in outdoor environment, and its accuracy range is generally 0.5 ℃ to 5 ℃ Although dry oven, large constant temperature bath, micro constant temperature bath, infrared calibrator and other heat sources can provide stable temperature, the accuracy of reference temperature provided by portable thermometer and standard thermometer exceeds that obtained directly from the display value of heat source The usual temperature calibration in laboratory involves the calibration of precision platinum resistance, industrial platinum resistance, high precision thermistor and precious metal thermocouple At this time, it is necessary to use the thermostatic bath and horizontal furnace with high temperature stability and uniformity (high temperature required to provide thermocouples) together with standard platinum resistance thermometer and high temperature detector These calibration systems provide calibration accuracy ranging from 0.02 ° C to 0.5 ° C The calibration of temperature based standards requires the use of fixed point devices (such as water three-phase point, tin point, mercury point, etc.), which, after correct "recurrence", can usually obtain high accuracy and excellent repeatability in the laboratory environment These systems are used to calibrate standard platinum resistance thermometers and precious metal thermocouples with an accuracy of 0.001 ℃ Solution temperature calibration seems difficult, but it can be done with the right knowledge and calibration products *Step is to understand the calibrated thermometer: what type of signal is the thermometer output, is it completely mechanical thermometer? What are the physical characteristics (size, shape, size and shape of the sensor in the temperature probe sheath)? In what temperature range? What is the accuracy? Is it calibrated in the laboratory or must it be calibrated in the field?
