Difference between PT 100 and PT 1000
Both, PT 100 and PT 1000 probes are resistance thermometers but have a different coefficient of temperature. Depending on the platinum used,
PT 1000 probes have a coefficient of temperature of 3,85 Ohm/°C and
PT 100 probes of 0,385 Ohm/°C. This means, at 0 °C the platinum of the PT 1000 sensor has a resistance of 1000 Ohm, at 1 °C of 1003,85 Ohm and so on. A PT 1000 probe has a higher gradient and thus offers a higher resolution. The inherent resistance of the connecting cable does not influence the measuring results of PT 1000 probes. For PT 100 probes, the measuring device compensates the inherent resistance of the connecting cable. Therefore not all devices can handle both probe types.
We produce temperature probes
according to your indications
Do you need a different temperature probe?
No problem - we can quote for your special requirements.
Coating custom
temperature probes and thermometers
We can coat your temperature probes or thermometers with a PTFE heat-shrinkable tubing so that they have the chemical resistance of PTFE. Even if the probes or thermometers break, there is no risk of contamination due to the PTFE coating.
Because of the thin coating, the probe or thermometer has slower response behavior.
For coating, your probe/thermometer has to resist a short-time temperature of minimum +250°C.
