Transmission Fluid Pressure Sensor – High‑Accuracy Oil Pressure Sensor for Automatic Transmission, Hybrid, and Powertrain Systems
Product Description
Transmission fluid pressure sensors are precision automotive‑grade sensing devices designed to monitor hydraulic pressure in automatic and dual‑clutch transmission systems.
Our sensors deliver accurate, real‑time pressure feedback to the transmission control unit (TCU) or powertrain control module (PCM), enabling smooth gear shifting, clutch engagement, and system protection. Built to withstand continuous exposure to hot oil, vibration, and electrical noise, these sensors ensure dependable performance across all driving conditions and vehicle platforms.
Advantages of Transmission Fluid Pressure Sensor
High measurement accuracy across a wide dynamic range for reliable TCU feedback
Fast response for precise gear shifting and hydraulic control
Excellent thermal stability and resistance to transmission fluids, ATF, and engine oil
Rugged stainless‑steel or ceramic construction for long‑term durability
Integrated temperature compensation for consistent accuracy across temperature ranges
Compact and sealed automotive housing for easy integration and installation
Analog or digital output options compatible with ECU / TCU systems
Low power consumption suitable for modern hybrid and EV transmissions
AEC‑Q100 and RoHS compliant for global OEM and Tier‑1 suppliers
