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 DAVS300-1512, with ID61 as an additional identifier. It measures hydraulic pressure in the machine's operating systems . The transducer converts mechanical pressure into an electrical output signal used for monitoring and control purposes.

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 . For hydraulic applications, the recommended mounting position is vertical with the pressure connection pointing upward to prevent media from freezing in the port and to avoid air pockets .

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. Common applications include closed-loop pump control and pressure compensation circuits .

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 with standard automotive connectors to prevent moisture and dust from entering . The sensor body should be grounded for proper operation and to meet EMC standards .

5. Maintenance
Routine maintenance is minimal. These sensors are generally maintenance-free . However, regularly check for oil leaks around the threaded connection and keep the electrical connector clean and dry. If the transducer fails or gives inaccurate readings, replace it as a complete unit. When installing replacement sensors, recalibration is required using a reference standard .
