Temperature Measurement Sensor

The industry grade temperature sensor supports a wide range of measuring go from basic applications to solutions in harsh environment.

Temperature measurement sensor.

The rtds and thermocouples support a broad range of application through the process industries. They all measure temperature by sensing some change in a physical characteristic. Resistance temperature relationship of metals. There are different types of temperature sensors used in the market today including resistance temperature detectors rtds thermocouples thermistors infrared sensor and semiconductor sensors.

This document goes into detail about the theory of operation types and considerations surrounding three types of temperature measurement sensors. In openbsd many of the i c temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework since openbsd 3 9 2006. Temperature is the most measured physical property in the world and thermocouples are the most popular sensor for temperature measurement. Further each sensor option comes in a variety of styles suited for different application needs.

The most commonly used sensors are. Integrated silicon temperature sensors. Each sensor option thermocouple rtd and thermistor is unique in its design and theory of operation. Common rtd sensing elements constructed of platinum copper or nickel have a repeatable resistance versus temperature relationship r vs t and operating temperature range the r vs t relationship is defined as the amount of resistance change of the sensor per degree of temperature change.

Most commonly temperature sensors are used to measure temperature in circuits which control a variety of equipment s. The seven basic types of temperature measurement sensors discussed here are thermocouples resistive temperature devices rtds thermistors infrared radiators bimetallic devices. Temperature measuring sensors come in a wide variety and have one thing in common. In addition to wide weather measurement network they are used also in over 50 of all industrial applications.

For example the lm35 ic from texas instruments is a precision temperature sensor ic that offers reading directly on the celsius scale and lm34 is another one. Therefore there are literally millions and millions of applications for thermocouples across every industry and sector. Sitrans ts temperature sensors are the perfect basis for precise and safe temperature measurement. Temperature sensors are one of the most common sensors on the planet.

Different industrial applications require different temperature sensors.
