Resistance thermometers may have two, three or four leads depending on the circuitry intended for the measurement of the resistance. Generally, the temperature sensitive element of a metallic resistance thermometer is in the form of a coil of fine wire. Resistance thermometers work by changing resistance with a change in temperature in a repeatable manner. While thermocouples use the Seebeck effect to generate a voltage, resistance thermometers use electrical resistance and require a power source to operate. This is necessary to meet calibration requirements. A resistance thermometer psychrometer consists of stainless steel-encased platinum resistance thermometers housed in ventilated cylindrical shields. RTD Resistance Thermometer Cables We are one of the largest stockists of leads and cables for use with Resistance Thermometer Assemblies in Europe. A resistance temperature detector, or resistance temperature device (both of which are abbreviated RTD), is a way to measure the temperature of a substance using this effect. A resistance thermometer is a thermometer that is used to measure extreme temperatures that range between -250oC and 700oC. The "alpha" () constant is known as the temperature coefficient of resistance and symbolizes the resistance change factor per degree of temperature change. The platinum is an unreactive metal and can easily be drawn into fine wires. Working Principle of Resistance Thermometer Resistance thermometers is also called RTD (resistance temperature detector). is the resistance at 0C, and the constants (for an = 0.00385 platinum RTD) are: Since the B and C coefficients are relatively small, the resistance changes almost linearly with the temperature. Definition: The platinum thermal resistance (PTR) uses platinum for determining the temperature. RTDs with a sensitivity of 0.375 and 0.392/C, as well as a variety of others, are also available. Resistance thermometers are sensors that are used to measure temperature. Large 5 digit, 14.2 mm character height LED display make process value easily visible at a distance. The changes in resistance caused by changes in temperature are detected by a Wheatstone bridge, as shown in Fig. Type K (chromel-alumel) thermocouples are also used as an alternative reference standard for temperature calibration up to 1000C. it uses the electrical resistance of the conductor to determine the temperature. An electrical current is passed through the sensor, the resistance element is used to measure the resistance of the current being passed through it. The resistance thermometer or RTD creates a change in resistance due to a change in temperature. The resistance thermometer, often called a Resistance Temperature Detector (RTD) is a common thermometer, well known for its stability and accuracy. In RTDs, a constant electrical current flows through a measuring conductor. Benefits. PVC, silicone rubber or PTFE insulators are used at temperatures below about 250C. Four-terminal sensing eliminates voltage drop in the measuring leads as a contribution to error. It works on the principle that the resistance of platinum changes with the change of temperature.
