Specification

Description

This 344-7392 pressure sensor is a core component designed for the engine of 312D2, 320D2, 336D2 and other series excavators, mainly used for pressure monitoring in the fuel common rail system. It adopts original-equipment-level threaded interface and sealing design, fits the original installation position perfectly, and can directly replace the original part without additional modification. The internal high-precision strain gauge measurement structure can collect fuel pressure data in real time and feed it back to the ECU, which is a key component to ensure the accuracy of engine fuel injection control and operation stability.-

Advantage

OE-level Compatibility: Manufactured in strict accordance with original equipment specifications, with fully matched thread size, interface definition and electrical parameters. No fault codes are generated after installation, compatible with mainstream models such as 312D2/320D2/336D2.
Durable Construction: Metal body and sealing ring design provide excellent vibration and impact resistance, capable of withstanding harsh conditions such as high temperature, oil pollution and humidity in the engine compartment, with no leakage or damage after long-term use.
Plug-and-play, No Calibration Needed: Precisely calibrated at the factory, it can be quickly put into use without additional matching after installation, greatly reducing the time cost of maintenance and replacement.
Stable Signal Transmission: Sealed connector design with strong anti-electromagnetic interference capability ensures stable signal transmission, avoiding engine idle instability and power drop caused by signal fluctuations.

Performance

High Measurement Accuracy: Adopts high-precision sensing elements, with pressure measurement error controlled to a minimum range, ensuring precise control of fuel injection quantity by the ECU, improving fuel efficiency and reducing abnormal fuel consumption.
Wide Temperature Adaptability: Can work stably in a wide temperature range of -40℃~125℃, adapting to engine operation requirements in different regions and working conditions, maintaining stable performance during cold start and high-temperature heavy load.
Fast Response Speed: Millisecond-level pressure signal response can capture fuel pressure changes in real time, feed back to the ECU quickly, and correct the fuel injection strategy in time to avoid engine power lag and fault alarms.
Long Service Life: Undergoes strict aging and durability tests, can withstand millions of pressure cycles, with a service life close to the original equipment standard, greatly reducing the frequency of later maintenance and replacement.
