Rtd Temperature Sensor Types
Another type of sensor is a thermistor temperature sensor which is relatively inexpensive adaptable and easy to use.
Rtd temperature sensor types. The resistance vs temperature relationship is well known and is repeatable over time. Resistance temperature detectors rtds also known as resistance thermometers accurately sense process temperatures with an excellent degree of repeatability and interchangeability of elements. It changes its resistance when the temperature changes like rtd sensor. A wide temperature range approximately 200 to 850 c li.
An rtd is a passive device. The rtd is composed of certain metallic elements whose change in resistance is a function of temperature. Each type is best suited for use in certain environments and applications. 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.
An rtd temperature sensor is a common device for temperature measurements in a wide range of industrial applications. Resistance temperature relationship of metals. An rtd resistance temperature detector is a sensor whose resistance changes as its temperature changes. The relative change in resistance temperature coefficient.
Rtd vs thermocouple or thermistor each type of temperature sensor has a particular set of conditions for which it is best suited. Pt100 rtd sensors rtd probes rtd transmitters sanitary rtds other industrial temperature sensors at discount prices. 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. 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.
It does not produce an output on its. In this article we take a look at how they work the most common types and their advantages and disadvantages. The resistance increases as the temperature of the sensor increases. Shop rtds at automation direct.
