Hirschmann KMD20T Tension Sensor Load Cell
The Hirschmann KMD20T is listed as a tension sensor/load cell for compatible XCMG crane monitoring configurations. It converts an applied mechanical load into an electrical signal used by the crane monitoring system. Correct mechanical installation, connector wiring and system calibration are essential; the KMD20T code alone does not confirm every application.
Identification Checklist
Sensor model: KMD20T
Manufacturer marking: Hirschmann
Complete label, serial or revision information
Connector type, pin count and cable length
Mounting dimensions, pin/bore sizes and load direction
Associated Hirschmann display or LMI system model
XCMG crane model, serial number and installation position
Application and Service Scenarios
The sensor may be investigated when a load or tension value is missing, unstable, implausible or outside the expected zero range, or when inspection finds physical or cable damage. Similar symptoms may be caused by connector corrosion, broken wiring, incorrect supply or signal voltage, mechanical binding, damaged mounting hardware, calibration loss or faults elsewhere in the monitoring system.
Diagnostic and Safety Notes
Crane load-monitoring components are safety-related. Record displayed values and fault codes, inspect the complete cable route and connector pins, and follow the approved Hirschmann/XCMG test procedure. Do not apply an improvised test load, bypass an alarm or return the crane to lifting service until correct indication and protective functions have been verified by qualified personnel.
Installation and Calibration
Install the sensor in the original orientation and load direction without side loading or impact. Use the specified pins, retainers and fastener procedure. Protect the cable from crushing, sharp bends and moving structures. If the applicable system requires zero setting or calibration, complete it with the correct service equipment and documented test conditions.
Frequently Asked Questions
Does KMD20T automatically fit every XCMG crane?
No. The mechanical interface, connector, signal specification and LMI configuration must match.
Can a fluctuating reading prove the load cell is faulty?
No. Wiring, connectors, mounting, power supply and system calibration should also be checked.
Can the sensor be installed without calibration?
Calibration requirements depend on the monitoring system and repair procedure. Verify them before returning the crane to service.
What information should be supplied for matching?
Send photos of the complete sensor and label, connector, mounting position, crane plate and Hirschmann display or controller label.
Export Packing
The sensing body and connector are protected from shock, moisture and cable strain. The package is cushioned in a rigid carton and labelled KMD20T for receiving inspection.
