The COGENG 10485476 Pressure Sensor is a high-precision, direct OEM replacement sensor specifically designed for Sany SY235 and SY365 excavators. These popular medium-to-large excavators are widely used in construction, mining, quarrying, and heavy infrastructure projects worldwide.
Depending on the specific application, this sensor monitors:
Hydraulic System Pressure – Main pump pressure, pilot pressure, or control valve pressure.
Engine Oil Pressure – For engine lubrication system monitoring.
Attachment Circuit Pressure – For hydraulic attachments (breaker, shear, compactor).
The sensor converts hydraulic or oil pressure into an electrical signal (typically 0.5V – 4.5V analog or variable resistance) that is sent to the ECU (Engine Control Unit) or MCU (Machine Control Unit) . This data is essential for:
| Function | How Pressure Data is Used |
|---|---|
| Load Sensing Control | Optimizes pump flow to match demand |
| Overload Protection | Prevents damage from excessive pressure |
| Pilot Pressure Monitoring | Ensures smooth hydraulic control |
| Engine Protection | Shuts down or derates engine if oil pressure is low |
| Diagnostics | Logs fault codes for maintenance alerts |
| Attachment Control | Regulates auxiliary hydraulic circuits |
Manufactured under ISO9001 certified processes, the COGENG 10485476 features a durable iron/stainless steel housing, premium rubber O-rings, and a precision sensing element to ensure accurate readings across a wide pressure range.
