The Multiquip 43120 Pressure Transducer is a genuine OEM component designed for STXDF, MD80, and MD105 series ride-on power trowels. Sourced directly from Multiquip, this transducer meets the exact electrical and pressure specifications required by the hydraulic systems on these machines. Verified fitment across the STXDF dual-fuel super-sized hydrostatic series and the MD80 and MD105 mid-sized hydrostatic trowels means you can order with confidence. DHS Equipment stocks this part to help you get your machine back in service fast.
Key Features
- OEM-Specified Signal Accuracy — Calibrated to the exact pressure range and output signal required by the hydraulic control system on these trowels, ensuring readings the machine's controller can act on correctly.
- Direct Plug-In Replacement — Matches the original connector, thread pitch, and port sizing for a straightforward swap with no adaptation needed at the hydraulic port.
- Confirmed Fitment — Fits STXDF, MD80, and MD105 hydrostatic ride-on power trowels from Multiquip's mid-sized and super-sized hydrostatic series.
- Protects Hydraulic System Integrity — A functioning transducer gives the control system accurate real-time pressure data, preventing over-pressure conditions and maintaining smooth blade pitch and drive response.
- Electrical Safety Compliance — As a genuine OEM sensor, part 43120 meets the original circuit voltage and impedance requirements, protecting the machine's control module from signal errors or electrical faults caused by an out-of-spec component.
A pressure transducer converts hydraulic fluid pressure into an electronic signal that the machine's control system uses to monitor and regulate hydraulic circuit performance. On hydrostatic ride-on trowels like the STXDF, MD80, and MD105, this signal is critical for maintaining correct blade pitch response and drive behavior under load. When the transducer fails or drifts out of calibration, the control system loses visibility into actual hydraulic pressure, which can cause erratic blade adjustment, sluggish drive response, or fault codes that take the machine out of service.
