Product Introduction:

1. Basic Identity
This is a pressure transducer, also referred to as a pressure sensor, designed for XCMG machinery. The part number is DAVS311-11. It measures hydraulic pressure in the machine's operating systems .

2. Installation Position
The transducer mounts directly into hydraulic lines or at pressure ports on the machine's control valves and pumps. It is typically installed at points where pressure monitoring is critical, such as the main hydraulic pump outlet or the implement control circuit . Threaded connections allow it to be secured into standard hydraulic ports.

3. Core Function
The transducer does two things. First, it senses hydraulic pressure through an internal sensing element that deflects under pressure. Second, it converts that mechanical deflection into an electrical output signal, commonly 4-20 mA or voltage, which is sent to the machine's control unit . The control unit uses this signal to monitor pressure, activate alarms, or adjust system operations.

4. Material and Construction
The housing is typically made from stainless steel for corrosion resistance in harsh worksite conditions . The sensing element is protected by a metal diaphragm. Electrical connections are sealed to prevent moisture and dust from entering.

5. Maintenance
Routine maintenance is minimal. Regularly check for oil leaks around the threaded connection. Keep the electrical connector clean and dry. If the transducer fails or gives inaccurate readings, replace it as a complete unit. Always use the correct replacement to match the pressure range and output signal of the original.
