Road Milling Machine Depth Indicator Sensor 106710 29637 for W130H W100 Parts

This 106710 / 29637 depth indicator sensor is the milling depth reference component used on W130H and W100 road milling machines. It feeds the depth reading back to the machine control system, which is what holds the cut at the value the operator has set as the machine travels along the reference.

Depth control is the part of a milling job that cannot be corrected afterwards. Once the drum has cut, the grade is set. A sensor that drifts, skips or reads through a jump of a few millimetres produces a surface that needs an overlay or a second pass, so replacing a failing sensor is cheaper than reworking the mat.

• Depth reading drifting during travel. The displayed depth slowly walks away from the set value with no change in the reference.
• Stepped or jumping values. Display jumps in fixed increments instead of changing smoothly as the machine moves.
• Depth loss on rough base. Reading drops out over milled surface joints or patches where the reference surface is uneven.
• Zero-point creep. The reading no longer returns to the calibrated zero after the machine is raised and lowered.
• Intermittent fault codes. Depth-related alerts appearing and clearing without any change in operating conditions.

Check the mounting bracket and reference arm first. A loose bracket, bent arm or worn contact produces the same symptoms as a failed sensor, and it costs nothing to rule out.

• Isolate the electrical system before unplugging the sensor connector.
• Inspect the connector pins and harness for corrosion, chafing or pulled wires before fitting a new unit.
• Mount the sensor on a clean, undamaged bracket face; contamination under the mount shifts the zero point.
• Set the reference arm and confirm free movement through the full travel range without binding.
• Recalibrate the zero point after installation and verify the reading against a physical measurement before milling.
