PT-854 compact pressure transmitter designed for EV thermal management, transmission hydraulics, and air compressors. IP68 waterproof with ceramic flat diaphragm.
Product Overview：
1，The PT-854 Pressure Transmitter is a specialized, automotive-grade pressure sensor engineered explicitly for New Energy Vehicles (EVs), thermal management networks, transmission hydraulics, and high-reliability fluid systems. Built with a high-hardness ceramic flat diaphragm, the PT-854 delivers extraordinary structural strength and overload resistance, guaranteeing zero fluid or refrigerant leakage even under extreme system overpressure.
2，Designed for space-constrained vehicle platforms, the PT-854 features a compact, lightweight architecture paired with a fully overmolded cable entry rated to IP68 submersion-grade waterproof performance. Driven by an advanced signal processing IC with full-span thermal compensation and reverse-polarity protection, the PT-854 offers exceptional resistance to thermal shock, vibration, and electromagnetic noise (EMC)—making it the premier OEM replacement for premium imported sensors.
Key Features & Highlights：
1，Tailored for EV & New Energy Thermal Systems: Engineered specifically for EV battery/motor coolant loops, automotive HVAC refrigerant lines, and automatic transmission hydraulics.
2，IP68 Submersible Molded Waterproof Protection: Fully overmolded cable entry shields internal electronics against condensation, washdowns, oil mist, and outdoor weather exposure.
3，Ceramic Flat Diaphragm with Burst Safety: Tough ceramic sensing core absorbs severe pressure surges, maintaining leak-proof structural integrity even during catastrophic system spikes.
4，Ultra-Compact Footprint for Tight Mounts: Space-saving mini design enables easy integration into dense engine bays, fluid manifolds, and compact pump skids.
5，Advanced Conditioning IC & Full Thermal Calibration: High-integration signal processor ensures accurate digital thermal compensation and long-term zero stability.
6，Flexible OEM/ODM Customization: Wide range of customizable process threads (NPT, BSP, Metric), wiring harnesses, and electrical output signals.
Applications：
1，EV & Automotive Systems: EV battery and electric motor thermal management loops, automotive HVAC, transmission hydraulic manifolds, and brake boosters.
2，Industrial Compressors & Water Pumps: Screw air compressors, water pump pressure telemetry, and fluid power manifolds.
3，Smart Appliances & Commercial Systems: Smart pressure cookers, commercial coffee machines, and high-pressure steam appliances.
