Stainless Steel Threaded High-Temperature NTC Temperature Sensor

Main Features:

This series comprises stainless steel threaded NTC temperature sensors specially designed for high‑temperature fluid applications in automotive electronics. Featuring an all‑stainless‑steel metal housing and a standard threaded mounting configuration, they are paired with high‑temperature‑resistant braided insulated cables and incorporate a highly precise NTC thermistor. These sensors can be directly mounted on pipeline interfaces of engines, transmissions, and other components, enabling accurate temperature measurement of fluids such as coolant, engine oil, and transmission fluid. They are widely compatible with the high‑temperature thermal management requirements of both conventional internal‑combustion‑engine vehicles and new‑energy vehicles.

Core Features

High-temperature and corrosion-resistant design : The all-stainless-steel housing offers excellent thermal conductivity, corrosion resistance, and high-temperature performance. Paired with a braided high‑temperature‑resistant cable, it can withstand the engine compartment’s extreme heat, oil contamination, and prolonged immersion in various fluids, ensuring a long service life.
High precision and fast response : Equipped with a high-sensitivity NTC chip and a highly thermally conductive stainless-steel probe, it significantly shortens the heat‑transfer path, enabling rapid temperature response. Temperature measurement accuracy reaches ±0.5°C, providing reliable high‑temperature data support for the engine ECU and the thermal management system.
Standard Threaded Installation and Sealing Performance It features a standard threaded interface, compatible with the factory‑mounted mounting holes of most vehicle models. The metal housing and sealed construction effectively prevent media leakage and external contamination, offering a high level of protection and ensuring reliable performance in vehicles subjected to high vibration and humid operating conditions.
Harsh operating condition adaptability The overall structure is made of high- and low-temperature‑resistant, aging‑proof materials, enabling stable operation across a wide temperature range of –40°C to +200°C and meeting the high‑temperature, high‑vibration requirements of automotive powertrain systems.

Typical application scenarios

Automotive engine coolant and oil temperature monitoring
High-temperature collection of transmission oil and hydraulic oil
New energy vehicle motor cooling system and high-temperature pipeline temperature measurement
Engine compartment exhaust system and heating module temperature monitoring
