The Multiquip RE552186 SCR Temperature Sensor is a genuine OEM component designed for DCA-series ultra-silent diesel generators including the DCA150SSJU4F, DCA220SSJU4F, and DCA300SSJU4F. As a direct OEM replacement, this sensor meets the exact output and calibration specifications required by Multiquip's emissions control system. Sourced directly through authorized Multiquip distribution, RE552186 ensures proper integration with the generator's Selective Catalytic Reduction system without adaptation. DHS Equipment supplies this part with verified part number accuracy so you can order with confidence.
Key Features
- Genuine OEM Calibration — Matched to Multiquip's exact temperature range and signal output specifications for the SCR aftertreatment system, ensuring accurate emissions monitoring.
- Direct Plug-In Replacement — Engineered to connect directly to the existing wiring harness on DCA-series generators, making installation straightforward for qualified technicians.
- Broad DCA-Series Fitment — Compatible with DCA150SSJU4F, DCA220SSJU4F, and DCA300SSJU4F ultra-silent generator models across both 50Hz and 60Hz configurations.
- Emissions System Integrity — A correctly functioning SCR temperature sensor keeps the generator's exhaust aftertreatment operating within its designed parameters, preventing fault codes and unplanned shutdowns.
- Emissions Compliance Critical — The SCR system is a regulated emissions control component; using a correctly specified OEM sensor helps maintain Tier 4 Final compliance during operation and inspection.
The SCR Temperature Sensor monitors exhaust gas temperature within the Selective Catalytic Reduction aftertreatment system fitted to Tier 4 Final diesel generators. This data is used by the engine control module to regulate urea injection (DEF dosing) and ensure the catalyst operates within its effective temperature window — keeping exhaust emissions within legal limits. When the sensor fails or delivers an inaccurate reading, the generator may trigger fault codes, derate power output, or shut down entirely to protect the emissions system, making prompt replacement essential to maintaining uptime and regulatory compliance.
