What Are PT100 and PT1000 Temperature Sensors?
PT100 and PT1000 are platinum resistance temperature detectors (RTDs) used for accurate temperature measurement.
The electrical resistance of the sensing element changes predictably with temperature. A connected controller or measurement system uses this change in resistance to determine the temperature.
The main difference between the two sensor types is their nominal resistance at 0°C:
PT100: 100 Ω at 0°C
PT1000: 1000 Ω at 0°C
Both are widely used where stable and reliable temperature measurements are required.
Because a PT1000 has a higher resistance, the resistance of the connecting wires generally has less influence on the measurement than with a PT100.
However, the most important consideration is compatibility with the controller or measurement system.

Temperature Measurement in Demanding Environments
A temperature sensor may have to do much more than simply measure temperature.
In agricultural and industrial applications, sensors can be exposed to dust, moisture, temperature fluctuations, cleaning and electrical interference. Reliable temperature measurement therefore depends on choosing a sensor designed for the conditions in which it will operate.
dol-sensors' temperature sensors are developed for demanding environments where robust construction, reliable measurements and long service life are important.
