Temperature measurement is essential for many applications. The G9864ST22F0 offers a range of temperature sensors to suit exactly to an application, offering a cost effective, reliable solution. Thermocouples, temperature probes and assemblies are offered for different applications.

Thermocouples

The thermocouple consists of two dissimilar metals, each containing a different temperature sensing element which when connected in a closed circuit generates a voltage proportional to the temperature difference between the two junctions. Thermocouples are often used for measuring higher temperatures. The G9864ST22F0 range of thermocouples is available in a range of sizes and lengths with a choice of type K, T, J, E and N thermocouple elements.

Temperature Probes

Temperature probes are contact sensors usually made of stainless steel. They come in a variety of shapes and sizes to suit the application. The G9864ST22F0 range offers temperature probes in a range of lengths with different temperature sensitivities, accuracies and response times. These probes are suitable for applications where direct contact with the medium is required.

Working Principle

The working principle of any sensor is based on its ability to detect changes in temperature. For thermocouples, the principle is based on the Seebeck effect. When two different metals are connected in a loop, a voltage is generated which is proportional to the temperature difference between the two junctions. This voltage can then be used to measure the temperature of the environment or the medium.

The principle of operation of a temperature probe is based on the resistance principle. The probe consists of a metal element, usually stainless steel, which has a temperature dependency. The resistance of the metal element varies with the temperature, so when it is connected to a voltage source, a change in the voltage can be detected. This in turn provides a measure of the temperature.

Application Field

The G9864ST22F0 temperature sensors are useful for a wide range of applications in industrial, medical and food applications. They can be used to measure temperatures in production processes, medical procedures, in food processing and in the laboratory. Typical applications include measuring temperatures of liquids, gases and surfaces. They can also be used to monitor room temperatures and provide temperature feedback in production processes.

Thermocouples are especially suited for measuring higher temperatures in industrial applications. Temperature probes can be used to measure liquids, surfaces and air temperatures in medical, food and laboratory environments. They are often used in monitoring and alarms systems, providing warning of temperature exceeding set limits.
