Resistance-based temperature sensors
PTC thermistor (PTC: Positive Temperature Coefficient):
These sensors, such as Pt100 or Pt1000, increase their resistance as the temperature rises and offer high accuracy and stability. A major advantage of these sensors is that the characteristic curve is linear and they are uniformly standardized. For example, the resistance of a PT1000 sensor at 0°C is always 1000 Ohm.
With S+S Regeltechnik we offer you the following PTCs (thermistors) depending on the temperature sensor:
- Pt100 sensors: Pt100 class A, Pt100 class B, Pt100 1/3 class B, Pt100 1/10 class B
- Pt1000 sensors: Pt1000 class A, PT1000 1/3 DIN class A, PT1000 1/10 DIN class A, Pt1000 class B
- Ni sensors: Ni1000 1/2 DIN class B, NI1000 class B
- NI1000TK5000 sensors
- LM235Z
- KTY sensors: KTY81-210, KTY81-110, KTY11-6
As we attach great importance to customer satisfaction, we can of course also install sensors that are not listed. To do this, simply send us a request.
Thermistors (NTC: Negative Temperature Coefficient):
NTC thermistors reduce their resistance as the temperature rises and are made of metal oxides or semiconductors.
S+S Regeltechnik has the following NTCs (thermistors) in its range:
- NTC1.8K
- NTC2.2K
- NTC10K
- NTC10K Precon
- NTC10K Carell characteristic
- NTC20K
As we attach great importance to customer satisfaction, we can of course also install sensors that are not listed. To do this, simply send us a request.
Basically, the higher/better the class, the more accurate the sensor. This accuracy is categorized in the DIN classes. The picture shows the different tolerances of the various sensor types. S+S offers you this in the download area under "Useful information". In the PDF you will also find the resistance table for each sensor
Thermocouples
Thermocouples consist of two different metals that generate a low electrical voltage when there is a temperature difference. They are ideal for use at high temperatures and offer a fast response.
