OEM 803591795 The XCMG Level Sensor (803591795) is a genuine OEM precision measurement device engineered to provide accurate, continuous fluid level monitoring for hydraulic tanks, fuel reservoirs, and lubrication systems on XCMG hydraulic excavators. This advanced level sensor, identified by part number 803591795, delivers reliable real‑time level data that enables precise machine control, prevents pump cavitation, and optimises fluid management, even under the extreme vibration, temperature fluctuations, and demanding conditions typical of construction, mining, and demolition operations.
Manufactured with robust stainless steel housing, a wear‑resistant float mechanism, and hermetically sealed electronics, the 803591795 level sensor offers exceptional durability, corrosion resistance, and long‑term measurement stability. Its exact OEM mounting flange, insertion length, and electrical interface (analogue or CAN) guarantee a direct plug‑and‑play replacement without modification, ensuring seamless integration with your XCMG excavator’s existing tank and control system, while preserving the machine’s original monitoring accuracy and safety characteristics.
The 803591795 sensor features a high‑resolution resistive or hall‑effect sensing element that provides continuous level output, a rugged stainless steel float that operates reliably in viscous or contaminated fluids, and a sealed IP67 connector that resists moisture and dust ingress. The output signal (0‑190 Ω, 4‑20 mA, or CAN J1939) is compatible with standard excavator displays and controllers. By providing accurate, dependable level information, this sensor plays an essential role in preventing pump damage, reducing unscheduled maintenance, improving fuel economy, and extending the service life of your excavator’s hydraulic and fuel systems in the toughest working conditions.
The 803591795 level sensor is constructed from high‑grade stainless steel with a precision‑machined float and stem, ensuring consistent buoyancy and smooth travel even in viscous or contaminated fluids. The hermetically sealed sensing element (resistive or Hall‑effect) provides a stable, repeatable output that is immune to fluid turbulence and foaming, delivering accurate level data in real time.
The sensor’s robust mechanical design incorporates a guide tube that prevents float binding, even when the machine is operating on steep inclines or under heavy shock loads. The electrical housing is potted with epoxy to protect against moisture, dust, and vibration, ensuring long‑term reliability in the harsh under‑hood and reservoir environments.
The output signal is factory‑calibrated to match the specific tank geometry and fluid characteristics, providing a linear relationship between level and output. The sensor can be configured for resistive (0‑190 Ω), analogue (4‑20 mA), or CAN J1939 output, making it compatible with most excavator control systems and displays.
By delivering accurate, drift‑free level information, the 803591795 enables the machine’s control system to perform tasks such as automatic refuelling scheduling, hydraulic oil temperature management, and protection against low‑level pump cavitation, all of which contribute to reduced wear and extended component life.
Whether installed in the hydraulic reservoir, fuel tank, or lubrication sump, this sensor provides the critical data needed to keep your XCMG excavator operating efficiently and safely.
The 803591795 level sensor utilises a precision‑wound resistive element or a contactless Hall‑effect sensor that provides an analogue voltage or current output proportional to the float position. The sensing element is protected by a stainless steel tube that isolates it from the fluid, eliminating corrosion and contamination issues.
The float is manufactured from 316L stainless steel or a high‑temperature nitrile rubber, selected for its excellent buoyancy, chemical resistance, and dimensional stability across a wide temperature range. The float is guided by a central rod that prevents side‑loading and ensures smooth, friction‑free movement.
The electrical connector is a rugged Deutsch DT series (IP67 rated) that provides a secure, sealed interface for power and signal. The connector is gold‑plated to prevent corrosion and maintain low contact resistance over thousands of mating cycles.
Each sensor undergoes a comprehensive factory calibration process that verifies accuracy, linearity, and repeatability across the entire measurement range. The calibration data is stored in the sensor’s non‑volatile memory, ensuring consistent performance throughout its service life.
Sample units from each production batch are subjected to thermal cycling, vibration testing, and salt spray exposure to validate long‑term durability and performance under harsh environmental conditions.
Accurate fluid level monitoring is essential for the longevity and reliability of the excavator’s hydraulic and fuel systems. Low hydraulic oil levels can cause pump cavitation, leading to rapid wear, reduced efficiency, and eventual pump failure. Similarly, insufficient fuel level can cause engine stalling, air ingestion, and damage to the fuel injection system.
The 803591795 level sensor provides real‑time, accurate level data to the machine’s control system, enabling automatic warnings and shutdowns before damage occurs. The sensor’s high resolution and stability ensure that even small changes in level are detected, allowing operators to take corrective action in a timely manner.
Field data from heavy excavation operations shows that machines equipped with genuine XCMG level sensors experience significantly fewer pump failures and reduced maintenance costs, improving machine availability and operator confidence. The sensor’s rugged construction and corrosion‑resistant materials ensure reliable operation even in the most challenging job site conditions.
Regular inspection of the sensor for signs of physical damage, fluid contamination, or connector corrosion is recommended; any compromised sensors should be replaced promptly with genuine 803591795 components.
By maintaining accurate, reliable level monitoring, this sensor plays a vital role in ensuring safe, productive excavator operation.
The 803591795 level sensor is designed for simple and reliable installation. Before installation, ensure the tank is depressurised and the fluid level is below the mounting port. Clean the mounting boss threads and apply a suitable thread sealant or O‑ring lubricant (if not pre‑assembled).
Screw the sensor into the mounting hole using the appropriate tool on the hex flats, taking care not to overtighten. Torque to the manufacturer’s recommended value (typically 40–60 N·m depending on thread size). Connect the electrical connector to the mating harness, ensuring it locks securely.
After installation, verify the sensor output using a multimeter or through the machine’s diagnostic display. The output should change smoothly as the float is manually moved (if accessible) or as the tank is filled and emptied. If the sensor is CAN‑based, check that the correct data is visible on the bus.
During routine maintenance, inspect the sensor for signs of fluid leakage, connector corrosion, or float sticking. Clean the connector pins and apply dielectric grease to prevent corrosion. If the sensor fails to operate correctly, replace it with a genuine 803591795 component to maintain system accuracy and reliability.
Periodic cleaning of the float and stem (if accessible) may be required when using viscous or contaminated fluids.
Investing in the genuine 803591795 level sensor delivers significant long‑term savings by preventing pump failures, reducing component wear, and avoiding costly downtime caused by hydraulic or fuel system breakdowns.
A faulty or inaccurate level sensor can fail to alert the operator to low fluid levels, leading to cavitation, overheating, and eventual pump seizure. The 803591795’s high accuracy and reliability eliminate this risk, ensuring that low‑level warnings are always issued in time.
Over a typical 10,000‑hour service life, the sensor’s robust construction ensures consistent performance, reducing the need for unscheduled replacements and minimising downtime.
