Definition – The resistance thermometer or resistance temperature detector (RTD) uses the resistance of electrical conductor for measuring the temperature.The resistance of the conductor varies with the time.This property of the conductor is used for measuring the temperature.The main function of the RTD is to give a positive change in resistance with temperature.
An electric thermometer uses electricity to measure temperature. An electric resistor known as a thermoresistor is the key to the electric thermometer. This sensor's resistance is changed by a fluctuation in temperature. A small computer calculates the change and converts the …

Resistance thermometers are equipped with platinum sensor elements which change their electrical resistance as a function of temperature. In our range of products you will find versions with connected cable as well as versions with connection head. A temperature transmitter can be installed directly in the connection head.

The electrical resistance of an electrical conductor is a measure of the difficulty of passing an electric current through a substance. It explains the relationship between voltage (amount of electrical pressure) and the current (flow of electricity). With more resistance in a circuit, less electricity will flow through the circuit. The inverse of resistance is conductance, a measure not much ...
Another electrical temperature system is based on the use of a thermistor. The usual type of thermistor is a little bead of metal oxide, the resistance of which—unlike the platinum resistance thermometer—falls exponentially as the temperature rises (Fig. 9.4).Special thermistors, however, are also available in which resistance rises with temperature.
As a resistance thermometer for low-temperature measurements of the order of 10 K. As an inrush current limiter device in power supply circuits, they present a higher resistance initially, which prevents large currents from flowing at turn-on, and then heat up and become much lower resistance to allow higher current flow during normal operation.
Pt100/Pt1000 resistance thermometer by WIKA. The sensor of a resistance thermometer features a temperature-dependent electrical resistance. This increases with the temperature and is therefore known as a PTC (positive temperature coefficient). With industrial measuring requirements, primarily Pt100 or PT1000 measuring resistors are used.
resistance thermometer (Also called electrical resistance thermometer) A type of electrical thermometer in which the thermal element is a substance with an electrical resistance that varies with the temperature. Such thermometers can be made with very short time constants and are capable of very accurate measurements.
A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this ...
Resistance Thermometers Resistance thermometers may be called RTDs (resistance temperature detectors), PRTs (platinum resistance thermometers), or SPRTs (standard platinum resistance thermometers). These thermometers operate on the principle that electrical resistance changes in pure metal elements, relative to temperature.

Definition: Resistance thermometer is a device that is used to determine temperature by the variation in the resistance of a conductor. It is commonly known as Resistance Temperature Detector (RTD) and is an accurate temperature sensor.. RTD is not used for dynamic temperature measurement.

A resistance thermometer has its strengths in the low and medium temperature ranges of -200 … +600 °C. In industry, mainly temperature sensors with Pt100 or Pt1000 measuring resistors are used. If the temperature sensor detects an increase in temperature, then its resistance also increases (positive temperature coefficient).
Other articles where Electrical-resistance thermometer is discussed: thermometer: Electrical-resistance thermometers characteristically use platinum and, like thermistors, operate on the principle that electrical resistance varies with changes in temperature. However, they can measure a much greater temperature range than thermistors.

25-07-2021· Modern platinum resistance thermometer consists of pure platinum wire wound on hollow pipe made up of insulating mica or ceramic, which is placed in porcelain sheath. Refer Fig. 2.19. Free ends of platinum wire are attached to long leads of low resistance copper wires. To measure change in resistance, Wheatstone bridge is used.
