Sheath diameter : φ0.5 to 2.0mm
Platinum Resistance Thermometer (PRT)

We have developed the extremely small 100Ω PRT elements, which can be set into φ0.5mm sheath pipe. Recently PRT probe diameters were not available for such a small application. If a probe smaller than 3.2mm was required, inaccurate thermocouples were used for the application. This capillary PRT is now available for a wide range of applications with real stability, accuracy, and speed.

1. 1. The smallest Platinum wire wound RTD
2. 2. Small aging variation.
3. 3. Better Reproducibility at the measuring temperature
4. 4. Better sensitivity.
5. 5. Higher stability because of lower self-heating.
