PT100 Sensors

Platinum resistance thermometers (PRTs) offer excellent accuracy over a wide temperature range (from -200 to 850°C). Sensors are interchangeable between different manufacturers, and are available in various accuracy ratings and packages to suit most applications. Unlike thermocouples, it is not necessary to use special cables to connect to the sensor.

Pico Technology supplies sensors (see below) that comply with BS1904 class B (DIN 43760): these sensors offer an accuracy of ±0.3 at 0°C. For increased accuracy we also supply tenth-DIN sensors (±0.03 at 0°C). Specialist manufacturers can provide sensors with 0.001 at 0°C accuracy (at a price). Please note that these accuracy specifications relate to the SENSOR ONLY. It is necessary to add the sensor error to the PT-104 error.

The following table provides a Temperature to Resistance for Platinum Resistance Thermometers, PT100 conversion. We have provided steps of 2 degrees Celsius from 0 - 200. We hope that this will be useful for Instrument, Electrical and Commissioning Engineers, for setting up instruments. Note the PT100 values are in ohms.
