The Bomag 05712989 Temperature Sensor is a genuine OEM component designed for Bomag tandem rollers and single drum rollers, including the BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 124 DH-3, BW 124 PDH-3, BW 125 ADH, BW 135 AD, BW 138 AC, BW 138 AD, BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 141 AD-4, BW 141 AD-4 AM, BW 151 AC-4, BW 151 AC-4 AM, BW 151 AD-4 AM, BW 154 AD-4, BW 154 AD-4 AM, and the C 815 C single drum roller. Sourced directly from Bomag, this sensor matches the original specification for a drop-in installation with no adaptation required on covered machines. Confirming the correct part number 05712989 before ordering ensures you receive the exact sensor your roller's control system expects.
Key Features
- OEM-Matched Signal Output — manufactured to Bomag's original resistance and voltage-output specification, so the machine's control unit reads temperature accurately without calibration adjustments.
- Direct-Connect Fitment — replicates the original connector type, thread pitch, and body dimensions for a straightforward swap on every covered model.
- Broad Roller Coverage — fits a wide range of Bomag BW-series tandem rollers and single drum rollers, including BW 100, BW 120, BW 124, BW 138, BW 145, BW 151, and BW 154 variants, as well as the C 815 C.
- Protects Engine and Hydraulic Systems — an accurate temperature reading allows the machine's management system to trigger warnings and protective shutdowns before overheating causes internal damage to the engine or hydraulic circuit.
- Genuine Bomag OEM Part — supplied as an authentic Bomag component under part number 05712989, carrying the same quality assurance as the sensor installed at the factory.
A temperature sensor monitors the thermal condition of the engine coolant, hydraulic fluid, or other critical system fluid and sends a continuous electrical signal to the machine's instrument cluster or control module. When the sensor reads correctly, operators receive timely warnings of rising temperatures, allowing them to respond before damage occurs. A faulty or out-of-specification sensor can cause false alarms, missed warnings, or erratic gauge readings — any of which can lead to unplanned engine or hydraulic failures that take a roller out of service.
