The Bomag 05742778 Temperature Sensor is a genuine OEM component designed for Bomag BW-series tandem rollers and single drum rollers, including the BW 174 AP-4i, BW 161 AD-5, BW 190 AD-5, BW 120 AD-5, BW 100 AD-5, BW 202 AD-5, BW 138 AD-5, BW 135 AD-5, BW 124 PDH-5, and BW 124 DH-5, among others. Sourced directly from Bomag, this sensor carries the same part number 05742778 used in factory assembly, so you can order with confidence that it matches the original specification. This temperature sensor installs directly in place of the factory unit with no adaptation needed, restoring accurate thermal monitoring to your machine.
Key Features
- OEM-Accurate Signal Output — Built to Bomag's original electrical and thermal specifications, this sensor delivers the precise resistance-to-temperature response the machine's control system expects — no calibration drift or false readings.
- Direct Drop-In Replacement — Matching the original connector type, thread pitch, and body dimensions of part number 05742778, this sensor seats and wires in exactly like the factory unit.
- Broad Tandem and Single Drum Coverage — Fits a wide range of BW-series machines, including BW 100, BW 120, BW 138, BW 161, BW 174, BW 190, and BW 202 tandem rollers, as well as BW 124 PDH-5 and BW 124 DH-5 single drum rollers.
- Protects Critical Engine and Hydraulic Systems — An accurate temperature sensor keeps the machine's monitoring systems informed, preventing undetected overheating that can lead to engine damage or hydraulic system failure mid-operation.
- Overheat Warning Integrity — A failed or drifting sensor can suppress genuine high-temperature alerts or trigger false shutdowns. Replacing it with a genuine OEM unit restores the reliability of your machine's thermal protection circuit.
A temperature sensor monitors thermal conditions within the engine or hydraulic circuit and sends a real-time signal to the machine's control system or gauge cluster. When the sensor is functioning correctly, operators receive accurate temperature readings that allow them to respond to developing heat issues before damage occurs. A worn or failed sensor can cause the system to misread temperatures entirely — either masking a dangerous overheat condition or triggering unnecessary shutdowns — making timely replacement essential for safe, uninterrupted compaction work.
