PT-850 IP68 waterproof pressure transmitter for water pumps and water treatment. Features anti-water hammer design, ceramic flat diaphragm, and XH-3 connector.
Product Overview：
1，The PT-850 Pressure Transmitter is a specialized, cost-effective pressure sensing solution engineered specifically for the water treatment industry, variable frequency pumps, and integrated water supply systems. Built with a high-durability ceramic flat diaphragm, the PT-850 offers high overload tolerance, guaranteeing zero fluid leakage even under severe system overpressure.
2，Engineered to solve liquid impact challenges, the PT-850 features specialized anti-water hammer dynamic protection to absorb high-pressure pulses caused by frequent pump start-stops. Featuring a fully overmolded end design with an IP68 submersion-grade waterproof rating and an integrated XH-3 2.54mm quick connector, the PT-850 provides broad-span thermal compensation and exceptional long-term stability—making it the top OEM replacement choice for global water systems.
Key Features & Highlights：
1，Specialized Anti-Water Hammer Surge Protection: Reinforced against high-pressure hydraulic shock spikes produced during pump cycling, extending sensor life in fluid lines.
2，IP68 Submersible Molded Waterproof Build: Fully overmolded cable entry prevents moisture ingress, making it suitable for damp pump houses and outdoor environments.
3，Ceramic Flat Diaphragm & Zero-Leak Overload: High-hardness, corrosion-resistant ceramic core ensures structural integrity and leak-proof safety under extreme overpressure.
4，XH-3 2.54mm Socket & Reverse-Polarity Protection: Equipped with an XH-3 2.54mm header for fast OEM wiring assembly, backed by reverse-wiring power protection circuitry.
5，High-Integration IC & Full Thermal Compensation: Advanced signal conditioning provides accurate thermal compensation and stable output across wide operating temperature spans.
6，Cost-Effective Drop-In Import Replacement: High performance-to-price ratio designed for mass OEM production, serving as a direct replacement for global pump pressure sensors.
Applications：
1，Water Pumps & Booster Systems: Variable frequency constant pressure pumps, non-negative pressure water supply skids, and secondary water supply pump houses.
2，HVAC & Refrigeration Equipment: Commercial air conditioning water loops, chillers, compressors, and cooling towers.
3，Water Treatment & Environmental Engineering: Reverse osmosis (RO) systems, water filtration, wastewater treatment, and pipe monitoring.
4，General Machinery: Medical fluid systems, automated vehicle washing rigs, and OEM fluid power units.
