Pt100 and Pt1000 sensors for accurate, repeatable temperature measurement
RTD sensors use a platinum resistance element whose resistance rises predictably with temperature. Compared with thermocouples, they offer higher accuracy and better stability at low and medium temperatures, which makes them the default choice for HVAC, food processing, pharmaceutical, water treatment and laboratory equipment.
This category covers our Pt100 and Pt1000 range: thin-film RTD elements, stainless-steel probe assemblies, surface and magnetic sensors, threaded and screw-in probes, submersible sensors and high-precision versions. Elements are available in Class A, Class B and tighter tolerances, with 2-, 3- or 4-wire connections depending on cable length and accuracy requirements.
Choosing the right RTD
- Element: Pt100 for general industrial use; Pt1000 when higher resistance and lower cable sensitivity are useful.
- Accuracy: Class A for critical measurement, Class B for general purpose; 1/3 DIN or AA on request.
- Wiring: 2-wire for short runs, 3-wire for industrial probes, 4-wire for laboratory and high-accuracy work.
- Mechanical: probe diameter, length, thread (M12, G1/4, G1/2, NPT), sheath material and cable type.
- Environment: waterproof, submersible, high-temperature or hygienic versions.
Typical applications
Chillers, boilers, heat pumps, air-handling units, water tanks, food and dairy lines, pharmaceutical skids, semiconductor equipment and calibration benches.
Quality and ordering
Every sensor is built in our ISO 9001 factory and can be supplied with a calibration certificate. Stock items ship within 48 hours; custom lengths, threads, connectors and cable materials are quoted on request. Tell us the temperature range, accuracy class, thread and lead length, and we will recommend the closest standard model or a custom build.
