In this video, Pyrosales gives an educational summary of Resistance Temperature Detectors. Video contents:
– What is a Resistance Temperature Detector (RTD)?
– How does it work?
– Element material types as well as working temperature ranges
– 2,3 and 4 wire configurations
– Considerations and suitable applications
Resistance Temperature Detectors, also known as RTDs and resistance thermometers, are temperature-sensing devices that change resistance at a predetermined rate in response to changes in temperature. They are circuit elements whose resistance increases with increasing temperature in a predictable manner.
Pyrosales’ RTDs are specially designed to ensure precise and repeatable temperature versus resistance characteristics. The sensors are constructed in a unique strain-free manner and use only high-quality RTD elements. Ceramic, wire-wound elements or flat film technology elements are used as per customer’s requirements to ensure the most suitable specification is supplied.
The main advantages of our RTDs include:
- High accuracy/precise measurement
- High signal-to-noise output, which increases the accuracy of data transmission and permits greater distances between the sensor and the measuring equipment
- Physical and chemical stability over a wide temperature range
- Standardisation (elements are available to meet, or exceed, the requirements of various standardisation agencies)
- Wide temperature operating range
- High temperature operating range
- Linear over a wide operating range
- Interchangeability over a wide range
- Repeatability, even after long exposure to temperatures within the operating range
