The term RTD is known as Resistance Temperature Detector that is a sensor is also known as resistance thermometer. The sensor is used to measure the temperature. Usually, they are available as a length of fine wire made of platinum nickel or copper, wrapped around a ceramic or glass core. 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. For nickel, the amount of change in resistance due to change in temperature becomes non-linear, at a temperature above 3500C. Based on their behavior, at different temperature ranges, materials are chosen to make the thin wire, which is used in RTD.
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.
