115640 Depth Sensor for Wirtgen Milling Machine

Product Introduction:

The depth sensor of a milling machine is a core component for precisely controlling milling depth. Integrated into the milling machine's operation system, it monitors the relative position between the milling drum and the ground in real time, feeds data back to the main control system, and realizes automatic adjustment and stable control of milling depth. It can preset milling depth according to construction requirements, automatically compensate for deviations caused by road undulations and equipment jolts during operation, avoiding uneven depth and unsmooth slope surfaces. Adaptable to different working conditions, it can flexibly switch between manual and automatic modes. Its shell has dustproof and shockproof features, able to withstand dust and vibration in milling operations. Routine maintenance only requires regular cleaning of the induction probe and parameter calibration, making it a key device to ensure milling accuracy and improve construction quality.

What are the common faults?

Common faults of the milling machine depth sensor include depth display deviation, no data feedback, frequent depth fluctuations and mode switch failure: display deviation is mostly due to dirty probes, inaccurate parameters or installation offset, so clean the probes, recalibrate and fasten the brackets; no data feedback may be caused by loose lines, power supply faults or damaged probes, so check the cables and power supply, and replace the sensor if damaged; depth fluctuations come from aged shock-absorbing parts, stuck debris or signal disorder, so replace shock-absorbing pads, clean debris and restart the controller; mode switch failure is often due to stuck buttons, program loopholes or slow response of hydraulic mechanisms, so clean button contacts, update programs, refill hydraulic oil or replace sealing rings. Timely troubleshooting of these problems can ensure the stable work of the depth sensor and milling accuracy.

How does a depth sensor work?

The working principle of the milling machine depth sensor centers on "real-time monitoring - signal transmission - automatic adjustment": it continuously monitors the relative position between the milling drum and the ground through an induction probe (such as ultrasonic, laser or contact probe), converts distance signals into electrical signals and transmits them to the main control system; the system compares the preset milling depth with real-time monitoring data, calculates the deviation value, and sends adjustment instructions to the hydraulic actuator to drive the milling drum up and down to correct depth deviation. During operation, if the depth changes due to road undulations or equipment jolts, the controller responds quickly and adjusts dynamically to maintain stable milling depth at all times. Some controllers also support manual/automatic mode switching: the automatic mode relies on closed-loop control logic to achieve high-precision and consistent milling operations, while the manual mode allows operators to directly adjust depth parameters.
