Temperature Measurement Sensor Types

They offer a linear response but have the lowest accuracy of the basic sensor types at 1 c to 5 c.

Temperature measurement sensor types. They can be used to detect solids liquids or gases over a wide range of temperatures. There are different types of temperature sensors used in the market today including resistance temperature detectors rtds thermocouples thermistors infrared sensor and semiconductor sensors. In addition to the characteristics of the sensors themselves operating range sensitivity linearity response time and so on you must consider the requirements each sensor type imposes on the measurement hardware. Contact temperature sensor types these types of temperature sensor are required to be in physical contact with the object being sensed and use conduction to monitor changes in temperature.

There are different types of temperature sensors like temperature sensor ics like lm35. Each sensor option thermocouple rtd and thermistor is unique in its design and theory of operation. This document goes into detail about the theory of operation types and considerations surrounding three types of temperature measurement sensors. Further each sensor option comes in a variety of styles suited for different application needs.

Temperature measuring sensors come in a wide variety and have one thing in common. The sensors used for measurement can vary from capillary bulb thermometers and bi metal sensors to sensors that use varying voltage signals or resistance values. Most commonly temperature sensors are used to measure temperature in circuits which control a variety of equipment s. In a temperature sensor the changes in the temperature correspond to change in its physical property like resistance or voltage.

Sensor thermistor thermocouple rtd pt100 temperature range. This document provides context and information to help you select the best temperature sensor for your application needs. A temperature sensor consists of two basic physical types. A temperature sensor as the name suggests senses the temperature i e.

These sensors are effectively two identical diodes with temperature sensitive voltage vs current characteristics that can be used to monitor changes in temperature. It measures the changes in the temperature. The seven basic types of temperature measurement sensors discussed here are thermocouples resistive temperature devices rtds thermistors infrared radiators bimetallic devices.
