Description
Product Overview
21634017 The oil pressure sensor is installed in the engine's oil passage. It is equipped with a high-precision pressure sensing chip that converts the oil pressure into an electrical signal and transmits it to the vehicle's electronic control system and dashboard for real-time monitoring of the lubrication system's condition. If the old sensor chip is aged, has a leaky seal, or gets water inside the connector, it may result in falsely high or low oil pressure readings, and cause unexpected alarms. By replacing this product, accurate oil pressure monitoring can be restored, preventing the bearing shells and crankshafts from wearing out due to insufficient lubrication. It is suitable for heavy trucks, large mining machinery, and heavy-duty loaders for maintenance and replacement.
Unique core features of this product
Integrated brass forged valve body, rust-proof and pressure-resistant, and not prone to deformation
The entire product is made by one-piece processing of brass, resistant to oil corrosion and high-temperature and high-pressure environments, and less likely to rust and crack under long-term high-temperature cabin conditions, with strong pressure-bearing capacity and no pressure leakage deviation in oil pressure collection.
Integrated hexagonal clamping platform in the middle, no damage to the threads during disassembly and assembly
The valve body is equipped with a standard hexagonal flat surface in the middle, and during maintenance, the wrench is clamped at the hexagonal position to apply force, completely avoiding the threads at both ends, eliminating thread slippage and tooth wear, and reducing assembly leakage and rework.
Yellow multi-pin waterproof plug with multiple seals and oil resistance
The top yellow thick plastic seal has a multi-layer waterproof and dust-proof rubber layer, resisting oil splashing from the cabin, rain, and dust erosion. In heavy-load and bumpy working conditions, the contact points of the plug remain stable without signal interruption or false fault alarms.
Black oil-resistant O-ring for matching, one-step assembly without oil leakage
Each sensor comes with an integrated rubber sealing ring that fills the gap between the body and the oil passage after being screwed in, providing double barriers against oil leakage, and eliminating the need for additional purchase of sealing gaskets.
High-precision built-in sensing chip, no drift in high and low pressure sensing
The internal ceramic pressure chip can stably sense under idle low pressure and heavy-load high pressure intervals, and the oil pressure value feedback is real-time without lag, eliminating false oil pressure alarms. Applicable scenarios
Suitable for heavy-duty freight trucks, large mining excavators, engineering loaders, high-power diesel generators, and equipment used for 24-hour continuous full-load, high-temperature, high-dust, and heavy-duty operations in mining areas and construction sites.
