To measure temperatures accurately, reproducibly and with long-term stability, platinum resistance thermometers (PT100) can be used in addition to mineral-insulated thermocouples. To make the right choice, it is important to check which requirements you have for accuracy, long-term stability and the temperature range, as well as which environmental conditions exist. ThermoExpert Germany has been advising its customers for over 10 years and finds a technical solution for really every challenge. We would be happy to advise you as well - contact us at any time, e.g. also via our chat function on the website.
Get a first overview of the most important differences and functions of thermocouple and resistance thermometer:
- In general, the measurement of thermocouples is done via two wires (thermocouple)
- can be used at higher temperatures Type K up to +1,200 degrees, Type J up to + 800 degrees
- does not exhibit self-heating
- Very robust against vibrations
- better up to eight times faster response time
- more robust and less sensitive to mechanical stress
- Very small sensor areas possible
Resistance thermometer PT100
- In resistance thermometers, the temperature is measured via a corrosion-resistant platinum sensor.
- measures in the temperature range from -200 to 650 degrees
- Effects due to self-heating must be tested
- Relatively sensitive to vibrations
- Measures more accurately than a sheath thermocouple
- Platinum reduces risk of contamination through oxidation
- High reproducibility of the measured values
- usually cheaper
