Coil-wound sensors for electric vehicles
Delta-R manufactures wound-head temperature sensors for electromobility on behalf of sensor manufacturers for the growing electromobility market. Speed, flexibility, and reliability, combined with the highest quality standards ;Made in Germany; have convinced an increasing number of customers during the pandemic. Wound-head sensors for electromobility are cable thermometers used for temperature monitoring of electric motors and batteries. These cable thermometers are temperature sensors with a cable extension and heat-shrink tubing insulation. These heat-shrink tubing temperature sensors are usually based on a Pt100 or Pt1000 element, which is extended in a 2-, 3-, or 4-wire configuration and then insulated with high-voltage-resistant heat-shrink tubing. Depending on the required temperature resistance, the sensors are insulated with high-voltage-resistant Kynar or PTFE heat-shrink tubing. Depending on the voltage rating, the sensors are insulated with single or multiple layers. The required insulation strength determines the insulation length as well as the type and position of the heat shrink tubing. Typically, the elements are extended with single-core stranded wire in the AWG 20 to AWG 28 range. The operating temperature range of cable sensors with heat shrink tubing insulation is between -70°C and +260°C. Winding-head temperature sensors with a wide variety of connection technologies are available on the market. Delta-R prefers welding as a connection technology because it requires no filler material and is also suitable for small dimensions. However, brazing or crimping connections are also common and possible mechanical connection methods.
