Threaded Insert-Type NTC Temperature Sensor

Main Features:

A threaded‑insert NTC temperature sensor specially designed for monitoring the temperatures of automotive engine coolant, engine oil, transmission fluid, and other media. It features a standard metal thread, a stainless‑steel probe, a high‑precision NTC thermistor, and an automotive‑grade waterproof connector. The sensor can be directly screwed into the engine’s water jacket, oil passages, or equipment’s hydraulic lines, enabling precise in‑medium temperature measurement. With advantages such as high‑temperature resistance, leak tightness, vibration resistance, and electromagnetic interference immunity, it is widely used for monitoring engine coolant temperature, engine oil temperature, transmission fluid temperature, and similar applications, providing stable and reliable temperature data to the vehicle’s electronic control system and ensuring safe engine operation and intelligent thermal management.
