2.1 Operating Principles Transmission fluid pressure sensors are devices that measure the pressure of transmission fluid within a hydraulic or powertrain system and convert this pressure into an electrical signal. These sensors typically include a pressure-sensitive element such as a piezoresistive diaphragm, strain gauge, or capacitive membrane. As the fluid pressure deforms the sensitive element, the resulting change in resistance or capacitance is measured and converted into a voltage or current output signal.
2.2 Key Performance Metrics ? Pressure range: may vary from low-pressure (0¨C10 bar) to high-pressure (100¨C500 bar) applications ? Accuracy class: common specifications include ¡À0.5%, ¡À1%, or ¡À2% of full scale ? Linearity and hysteresis: important for consistent readings across the full pressure range ? Response time: typically less than a millisecond for fast-responding hydraulic applications ? Temperature drift: necessary compensation to maintain accuracy from ¨C40 ¡ãC to +125 ¡ãC
2.3 Material Considerations Stainless steel, nickel-plated brass, or corrosion-resistant alloys for sensor housings and diaphragms. Fluoroelastomers, PTFE, or EPDM for seals and o-rings to resist high temperatures and provide chemical compatibility with the fluid. Electronic modules in hermetically sealed enclosures to protect against contamination.
