Question

What's the difference between a Pt100 and JPt100 resistance thermometer?

Answer



In January 1, 1989, the JIS standard for platinum resistance thermometers (Pt100) was revised to incorporate the IEC (International Electrotechnical Commission) standard. The new JIS standard was established on April 1, 1989. Platinum resistance thermometers prior to the JIS standard revision are distinguished as JPt100. Therefore, make sure that the correct resistance thermometer - Glossary of Industrial Automation">platinum resistance thermometer is being used.

The following table shows the differences in appearance of the Pt100 and JPt100.

Note: OMRON discontinued production of JPt100 Sensors in March of 2003.
