RTDs-Resistance Temperature Detectors

The Transmitter Shop (TTS) provides various temperature measurement devices to its process industry customers. Resistance Temperature Detectors (RTD) are one of the most ordered temperature measurement devices in its inventory. These detectors feature resistors, which changes their resistance values as per the change in temperature. These temperature measurement devices are known for their reliability, accuracy, and stability in harsh process environments.
  1. Assembly
  2. RTD

The RTD element features a coil made from fine wire, which is neatly wrapped around a glass or ceramic core. The element is very fragile, and is protected by a sheathed probe. The RTD element is made from platinum, which is known for its stability in harsh environments, and strong resistance to oxidation or corrosion. A small excitation current is passed through the element, and the voltage proportional to the resistance is measured, as well as converted to temperature calibration units.
