Rtd Temperature Sensor Types

Each type is best suited for use in certain environments and applications.

Rtd temperature sensor types.

Rtds offer several advantages. An rtd temperature sensor is a common device for temperature measurements in a wide range of industrial applications. The resistance increases as the temperature of the sensor increases. 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.

The rtd is composed of certain metallic elements whose change in resistance is a function of temperature. An rtd resistance temperature detector is a sensor whose resistance changes as its temperature changes. A wide temperature range approximately 200 to 850 c li. Resistance temperature relationship of metals.

Resistance temperature detectors rtds also known as resistance thermometers accurately sense process temperatures with an excellent degree of repeatability and interchangeability of elements. The relative change in resistance temperature coefficient. This version of internet explorer is either no longer supported by microsoft or is obsolete and some features of our store may no longer be supported. It can then notify the system either of the actual temperature or if the detection circuit is more intelligent when a temperature control event occurs.

It does not produce an output on its. Thermistors are made from manganese and oxides of nickel which make them susceptible to damages. Pt100 rtd sensors rtd probes rtd transmitters sanitary rtds other industrial temperature sensors at discount prices. The resistance vs temperature relationship is well known and is repeatable over time.

In this article we take a look at how they work the most common types and their advantages and disadvantages. Another type of sensor is a thermistor temperature sensor which is relatively inexpensive adaptable and easy to use. Temperature sensor types temperature detection is the foundation for all advanced forms of temperature control and compensation the temperature detection circuit itself monitors ambient temperature. Resistance temperature detectors rtds available today can generally be categorized into one of two basic types of rtds depending on how their temperature sensing element is constructed one type of rtd contains thin film elements and the other type of rtd contains wire wound elements.
