The electrical temperature measuring at WIKA is divided into two groups of sensors:
- Resistance thermometers (resistance sensors)
- Thermocouples
                                             
                                            
                                                Resistance thermometers
Resistance thermometers are equipped with platinum sensor elements which change their electrical resistance as a function of temperature. In our range of products you will find resistance thermometers with connected cable as well as versions with connection head.
