A industrial thermometer is an instrument designed to measure and indicate the temperature of a specific application or condition.
An Industrial Thermometer, commonly known as a “Liquid-In Glass” or Light-Powered Digital Thermometer, is installed at the point of measurement and is usually read from that location.
Which thermometer is used for industrial application?
Principles of Operation:
Liquid-in-Glass
This thermometer is comprised of a liquid-filled sealed glass tube and bulb, which is affixed to the front of a metal temperature scale, and extends into a metal bulb chamber (stem).
Flaked graphite is used within the bulb chamber to transfer the measured temperature to the glass bulb. Temperature changes cause the thermo-active fill to expand or contract within the tube. This activity is instantly visible in the tube against the calibrated markings of the temperature scale. For purposes of readability, the tube is formed with a lens front to create a magnified indicating column.
Light-Powered Digital
This thermometer is comprised of a thermistor wire that extends into the stem. Flaked graphite is used to transfer the measured temperature to the thermistor. Temperature change causes a change in the output of the thermistor; this output is translated through a pre-programmed algorithm in the microprocessor resulting in a digital display of the temperature.
All industrial thermometers should be carefully selected to meet the demands of the particular application.
The information is offered only as a guide to assist in making the proper selection. Improper applications may cause the failure of the instrument, resulting in possible personal injury or property damage. For applications where the process media may be corrosive or contained under pressure, the use of a thermowell is required to prevent damage to the thermometer and facilitate its removal from the process.
Thermowell thermometer
For applications where the process media may be corrosive or contained under pressure, the use of a thermowell is required to prevent damage to the thermometer and facilitate its removal from the process.
Thermowells are available in various lengths, connections, sizes, and materials.
How to calibrate a digital thermometer?
A digital thermometer should always return accurate readings. Whether you use it for measuring body temperature, atmospheric temperature, or any other relevant use.
