New e-motor IP68 encapsulated precision RTD temperature sensor

The new IP68-rated Heraeus EC3032 Pt1000 temperature sensor assembly from ATC Semitec, is ideal for use in e-motor applications.

With a temperature range of -50°C to +200°C (with a short-term rating of up to 250°C for 50 hours) it offers precise, and robust temperature sensing solution for harsh automotive environments. In addition, internal results confirm that the sensors are both oilproof and oil-tight. To that end Heraeus are currently applying the EC3032 for AEC-Q200 component approval.

The sensor consists of a Pt1000B element terminated onto 24AWG PTFE wire and then encapsulated in a tough high-temperature shrink tube that is back-filled.  This creates an IP68 rated sensor that has a dielectric strength of 6kV.

As well as e-motor applications, the sensor can be used in rapid charging plugs, battery temperature monitoring, industrial motors, automation equipment and high temperature heating elements.
