The term RTD is known as Resistance Temperature Detector that is a sensor is also known as resistance thermometer. Temperature is measured with the help of the sensor. They are normally supplied in the form of a strand of very fine wire, in platinum nickel or copper, coated in ceramic form or glass and in the middle. This sensor makes use of the temperature or resistance relationship of the wire to measure the temperature. The RTD has resistance relationship that can find the amount of change happened to the resistance value of the sensor, for a degree change in the temperature. Platinum metal has a stable resistance-temperature relationship across a wide range of temperature. With nickel, the resistance change resulting to change in temperature becomes non-linear above a temperature of 3500C. Materials used in the thin-wire (used in RTD) are selected based on how they behave at various temperature ranges.
RTD can be constructed in different forms and in some cases, they are better than couples for stability, accuracy, and repeatability. It required electrical power to operate but thermocouple uses Seebeck effect to generate a voltage where RTD makes use of electrical resistance. Our designed and fabricated with high-quality materials and latest technology, these detector are available are varied provisions. We deliver these detectors to clients that meet their requirements at a competitive market price.
