What is the difference between a Pt100 and a Pt1000?

Despite their similar names, the Pt100 and Pt1000 have differences in their models and distinct features. As industry expert Process Parameters explains (https://www.processparameters.co.uk/pt1000/), you ought to select the ideal temperature sensor that suits your need. Each model has a different Resistance Temperature Detector (RTD), also known as a Resistance Thermometer.
What are Pt100 and Pt1000 Sensors For?
These sensors measure the temperature of the following:
- Surfaces
- Air
- Liquids
Thermometers and data recording equipment facilitate these measurements by the sensors. One can find them in various applications. Most common include:
- Ovens
- Grills
- Laboratories
- Food processing equipment.
Pt in their labeling refers to platinum. It describes the material making up the sensors, and the numbers give the ohmic value of the sensor at zero degrees centigrade. These sensors are consistent, accurate, and stable.
Pt100s are the external temperature probes that one plugs into circulators to measure the temperature of the contents of a reaction vessel. Pt1000s are the external temperature probes that you can plug into a hotplate and insert into a probe hole or a flask.
The RTDs are reliable, accurate, versatile, and easy to install. Platinum makes the sensors suitable as it is a popular metal with ideal characteristics for temperature measurements.
Distinction between Pt100 and Pt1000
The Pt100 has lower resistance and is suited for three and four-wire circuit configurations. On the other hand, the Pt1000 is suitable for two-wire circuit configurations. As the Pt100 sensors have less resistance, the resistance from the lead wires has a …
