XCMG Crane Pressure Transducer DAVS311-11
DAVS311-11 is listed as a pressure transducer for selected XCMG crane hydraulic or LMI monitoring systems. It belongs to a different model reference from the DAVS300 sensors and should be identified by the complete label and system data.
Identification Checklist
Full DAVS311-11 reference and manufacturer label
XCMG crane model and complete serial number
Pressure range and electrical signal stated on the unit
Connector housing, key position and pin count
Pressure-port thread and sealing geometry
Installed circuit and controller input assignment
Any adapter, cable or mounting hardware included
Application and Service Scenarios
The transducer may be required after a measured discrepancy confirms that the sensor output no longer represents actual hydraulic pressure, after intermittent or missing signal diagnosis, or after physical connector, housing or port damage. It can also support a verified control-system refurbishment. Actual pressure faults must be distinguished from sensor faults.
DAVS311 and DAVS300 Model Families
A similar purpose does not make DAVS311-11 interchangeable with DAVS300-2511, 2512, 1511 or 1512. The pressure range, electrical output, connector, port and calibration can differ. Cross-reference only with documented technical evidence.
Testing and Installation
Compare the system reading to a suitable reference gauge and verify power, ground and signal. Depressurize the circuit before removal and keep the port clean. Use the confirmed seal without thread adapters unless approved. After installation, verify the reading through the required operating range and perform any necessary calibration.
Packing
The port and connector are protected, and the sensor is sealed in anti-static moisture-resistant cushioning. DAVS311-11 is printed clearly on the package.
Frequently Asked Questions
Can DAVS311-11 replace a DAVS300 sensor?
Only with documented confirmation of range, signal, connector, port and system calibration.
What proves the sensor is inaccurate?
Its output should be compared with a suitable reference pressure while the electrical circuit is verified.
Should an adapter be used for a different port?
Not unless the complete pressure rating, sealing method and installation are technically approved.
