TDK launched a new B58101A0109A * (HP100) series heat pump sensor. This is a NTC (negative temperature coefficient) sensor specially designed to meet the requirements of automotive applications. It can indirectly measure the temperature of refrigerant in the pipeline by measuring the surface temperature of the pipeline. The new element is suitable for severe working conditions and has a series of characteristics and advantages, such as: pipe clamp design, and the standard is applicable to 12.8 mm pipe diameter; The operating temperature range is - 40 ° C to+150 ° C; Immersed in water for up to 500 hours; The response time is less than 7 seconds; Comply with AEC-Q200 standard, with dielectric strength up to 1250 V AC/10 seconds (important standard for electric vehicle application); Low temperature tolerance of ± 0.3 K at 85 ° C nominal temperature ensures high control accuracy.

The tube clamp design makes the sensor very easy to install. The refrigerant temperature can be measured without entering the coolant or refrigerant circuit, which can minimize the risk of leakage. In addition, the sensor is robust and durable. Typical applications include the measurement of the temperature of the heat pump refrigerant, which is an important part of the thermal management of the high-voltage battery of electric vehicles (BEVs).
