Clip-on NTC Sensors for Heat Pumps in E-mobility

TDK Corporation's B58101A0109A* (HP100) series of heat pump sensors measure the refrigerant temperature indirectly via the pipe’s surface temperature. The NTC-based sensors are specifically designed to meet automotive requirements. Standard for pipe diameters of 12.8 mm, this clip-on design can operate in harsh environments from -40°C to +150°C and is water immersion resistant for up to 500 hours. The response time is less than 7 s. The AEC-Q200 qualified sensors offer a high dielectric strength of 1250 V_AC for 10 s, an important criterion for use in EVs. Low-temperature tolerance of ±0.3 K at a nominal temperature of +85°C ensures high control accuracy.
