Pt100 Sensor (PRT) with Standard Plug - up to 600°C

Mineral Insulated Resistance Thermometers - Pt100 Sensors

  • Two styles of RTD Pt100 sensor are available; Type 17's, our most popular style, are economical, semi flexible and suited to a wide variety of industrial applications up to 500°C. Type 18's are best suited for applications up to 600°C or where a high accuracy element is incorporated
  • Custom built to your specification and terminated in a choice of miniature plugs rated to 220ºC or 350ºC
  • Alternatively, we have a large range of sensors available to buy online in various diameters and lengths
  • High accuracy, repeatability and reproducibility as simplex, duplex or triplex element assemblies
  • Wide operating temperature range of -100ºC to +600ºC
  • Available in 2, 3 and 4 wire configurations, in grade B, A, 1/3, 1/5 or 1/10 accuracy
  • 316L Stainless Steel sheathed and manufactured to IEC 60751
Sheaths can generally be bent and twisted to suit the application (do not bend within 50mm of the tip)

Frequently Asked Questions

  • What is an RTD Pt100 sensor, and how does it work?
    An RTD (Resistance Temperature Detector) Pt100 sensor measures temperature by detecting changes in electrical resistance. The "Pt" stands for platinum, the material used in the sensing element, and "100" refers to the resistance value of 100 ohms at 0°C. As the temperature changes, the resistance of the platinum element varies, allowing for accurate temperature measurements.
  • How accurate are RTD Pt100 sensors?
    RTD Pt100 sensors offer high accuracy and stability, with industrial-grade elements ranging from Class B (±0.3ºC at 0ºC) to Class A (±0.15ºC at 0ºC). Higher precision options, such as 1/10 class elements, provide an accuracy of ±0.03ºC at 0ºC. These sensors are widely used in industrial, laboratory, and scientific applications requiring high precision. Additionally, we offer calibration services in our UKAS accredited laboratory.
  • What is the temperature range for RTD Pt100 sensors?
    The temperature range of an RTD sensor depends on factors such as the construction, sheath material and insulation used in the construction. While some platinum elements can withstand temperatures up to 850°C, the overall sensor design will limit the maximum temperature rating. Please check the product specifications for the exact temperature range based on the sensor’s construction. If you need any advice, our engineers are happy to assist!
1 Sensor Style Temperature Range
17 Type 17 - Semi flexible, Mineral Insulated
Our most popular style
-100ºC to +500ºC
18 Type 18 - Semi flexible, Mineral Insulated
Good for high accuracy, high temp applications
-100ºC to +600ºC
Note: Some wiring and number of element configurations may not be available in all diameters

Assemblies with pot seals are supplied with short tails as shown. However, where leads are several metres or more long, it is more suitable to have an overall sheathed cable. We recommend the following cables, which are 7/0.2mm, laid flat and overall sheathed constructions. Other cables are available, please contact us for details.
