Platinum RTDs & Linear PTC Sensors
Why use a Platinum RTD Sensor?
Platinum Resistance Temperature Detectors (RTDs) are highly stable temperature sensors widely used throughout many industries, controlling temperatures up to 500°C or even higher.
Our Pt elements are manufactured by Heraeus using a thin layer of Platinum deposited onto a ceramic substrate which is then laser-trimmed to meet the exacting requirements of DIN EN 60751 (IEC 751). They have a linear PTC characteristic which is very well defined and readily interchangeable with other Pt elements of the same tolerance class; Class A, Class B, 1/3 DIN etc.
They have been used for many decades to measure temperature in laboratory and industrial processes and have a deserved reputation for high accuracy, excellent repeatability and high stability.
Typical applications include;
- Automotive electronics
- Industrial electronics
- Medical electronics
We also supply IP68 rated Platinum sensors and SKTY PTC linear sensors which have a steeper slope offering improved accuracy up to 150°C.

- Heraeus Platinum Pt100, Pt500,& Pt1000 RTD Elements
The Heraeus range of thin-film 2-wire platinum sensors are available from ATC Semitec. These are some of the smallest RTD elements available and conform to DIN EN 60751 (IEC 751). Based on a 2mm x 2mm x 0.8mm ceramic substrate, Pt100, Pt500 or Pt1000 sensor elements are laser-trimmed for high accuracy and sealed in glass to ensure complete integrity.
They are highly stable and suitable for use up to 500°C (Class B) or 300°C (Class A), and offer interchangeability and fast response times.
Suitable for a within a wide number of industries including use automotive and medical devices.ATC Semitec IP68 Waterproof Platinum Sensors
For applications where a high IP rating is required, our ATC Semitec IP68 Pt100 (or Pt500/Pt1000) sensors ensure that water ingress will not be a problem.
Moulded in TPE, the sensing portion is 5mm dia. x 20mm long and is available in single or double-insulated formats. The double-insulated versions offer a dielectric strength up to 3.75kV.
ATC Semitec SKTY Sensors & Linear PTC Elements
- Suitable for continuous use from -50/+110°C, they can also be used to 125°C for periods of up to 3000 hours.
- Utilising one of our platinum RTD elements, we supply Pt100, Pt500 or Pt1000 class B sensors with an accuracy of ±0.15K.
- 4 wire Class A platinum sensors are available offering an even higher degree of accuracy.
The SKTY series linear PTC sensing elements from ATC Semitec offer neat replacements for the once common KTY temperature sensors.
Our SKTY sensor elements are mounted on a small 3mm x 6mm p.c.b. and are available with R25 values of 1kohm and 2kohm with ±1% tolerances.
- Operating temperature range -50°C/+150°C
- Steeper linear slope improves accuracy
- R25 tolerance ±1% at 25°C
- Excellent long-term stability
- Linear Output
SKTYs can also be supplied as IP68 rated moulded sensors (see above) with single or double-insulated leads. Other custom probe formats also available as required.
