Description
Product Overview
21202753 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 instrument and the electronic control unit, enabling real-time monitoring of the lubrication system's condition. Old sensors may experience false alarms due to internal chip aging, thread seal leakage, or water ingress in the plug, resulting in inaccurate oil pressure data. Replacing this product can restore accurate oil pressure monitoring, preventing damage to the crankshaft and bearing due to insufficient oil lubrication, and is suitable for heavy trucks, large excavators, and generator sets for maintenance and replacement.
Unique core features of this product:
Thickened galvanized hexagonal metal valve body, integrated protection for disassembly and assembly
The main body is forged and formed from galvanized alloy steel, with a standard hexagonal clamping platform in the middle section. The wrench can clamp the hexagonal position for disassembly, and it will not wear the bottom threads; the galvanized layer isolates the oil and moisture corrosion, and it is less likely to rust and leak under long-term high-temperature conditions.
Precise external thread oil passage interface, sealing tightly without oil leakage
The bottom has standard uniform toothed threads, and the screw is tightly fitted into the oil passage of the body, cooperating with the sealing gasket to completely block oil leakage. The oil pressure collection has no pressure loss, and the numerical feedback is accurate without lag.
Top snap-fit waterproof plug, resistant to oil and vibration
The upper part is a black integrated plastic sealed connector, with multiple layers of internal waterproof and dust-proof rubber rings. In the mining area, rainwater, engine oil immersion, and long-term vibration conditions will not cause oxidation and poor contact of the pins, and the oil pressure signal can be continuously and stably transmitted.
Built-in highly sensitive pressure chip, stable collection in high and low pressure ranges
The internal integrates a high-precision ceramic pressure sensing chip. It can accurately sense the idle low pressure and heavy load high pressure ranges, and there is no signal drift, eliminating false oil pressure alarms and false fault codes.
Comprehensive high-temperature and low-temperature sealing structure, suitable for harsh conditions
A grease-resistant sealing ring is embedded in the connection between the valve body and the plug to prevent the oil from eroding the internal chip through the gap, and the sealing component will not harden and fail under low-temperature and high-temperature conditions in the engine compartment. The service life is longer. Applicable scenarios
Suitable for heavy-duty freight trucks, large mining excavators, heavy-duty loaders, high-power stationary 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.
