What are the Uses and Types of RTDs & RTD manufacturers?

Resistant Temperature Detector (RTD) is a type of temperature sensor, often referred to as resistance thermometers. Its works on the basis of change in resistance of metal due to change in temperature.

RTD is used in a variety of applications and is preferred over other types of temperature sensors for its accuracy, ease of use, repeatability, and cost. Temperature sensors are used across different domestic and industrial applications.

Resistance thermometers are most commonly used for temperature measurement from -200C to 600C, some sensors are designed to operate as high as 1000 C. Resistant Temperature Detectors are available with a variety of resistance element materials.

Two Most Widely Used Sensor Types Are:
1. Wire-wound RTD

This type of RTD has a small diameter wire, most commonly of platinum that is wound in a coil placed inside a ceramic/glass insulator.

Extension wires are welded to this platinum coil that extend outside the insulator body.

This type of sensor is longer in length and are more delicate compared to Thin Film. Wire wound RTD have good accuracy over wider temperature range.

2. Thin-film RTD elements
