Core Features High-Accuracy Pressure Sensing: The PRT-B10 is engineered for precise pressure monitoring and control, with an actuation accuracy of ±1% full scale (FS). Its sensitive diaphragm mechanism ensures reliable triggering at user-defined setpoints, minimizing false signals even in dynamic pressure environments (e.g., pulsating fluid lines). Broad Pressure Range Adaptability: Designed to cover a versatile pressure spectrum (typically 0.1–10 bar, with sub-models for low-pressure: 0–2 bar or high-pressure: up to 25 bar). This flexibility makes it suitable for both low-pressure applications (e.g., air lines) and medium-pressure systems (e.g., hydraulic circuits). Robust Industrial Build: Features a rugged metal housing (typically aluminum alloy with anti-corrosion coating or brass) that resists mechanical impact, vibration, and environmental wear. Wetted parts (in contact with media) are made of brass or stainless steel (304), ensuring compatibility with most industrial fluids (oils, water, air, inert gases). Flexible Switching Logic: Supports SPDT (Single Pole Double Throw) switching configuration as standard, allowing both "normally open (NO)" and "normally closed (NC)" outputs. This enables direct integration with alarms, pumps, valves, or PLCs for automated control. Wide Environmental Tolerance: Operates reliably across a temperature range of -20°C to +80°C (extended-temperature sub-models up to +120°C available), and maintains performance in humidity levels up to 95% (non-condensing). Its IP65 protection rating shields internal components from dust and water splashes. Easy Installation & Calibration: Equipped with standard 1/4" NPT or BSP process connections for quick pipe mounting, and a rotating electrical terminal block for flexible wiring. The external adjustment screw allows on-site calibration of pressure setpoints without disassembling the switch. Typical Applications The Parker PRT-B10 pressure switch is a workhorse for general industrial pressure control, widely used in: Hydraulic & Pneumatic Systems: Monitors system pressure in hydraulic power units (e.g., machine tools, presses) to prevent over-pressurization; controls air pressure in pneumatic circuits (e.g., conveyor belts, robotic arms). HVAC & Refrigeration: Regulates pressure in chilled water lines, refrigerant circuits (e.g., air conditioners, cold storage units), and boiler feedwater systems to maintain efficient operation. Water & Wastewater Treatment: Triggers pumps in water supply systems (e.g., boosting pressure in municipal pipelines) or monitors pressure in filtration units (e.g., sand filters, reverse osmosis systems). Manufacturing & Automation: Ensures consistent pressure in process lines (e.g., chemical dosing, paint spraying) and acts as a safety interlock for machinery (e.g., stopping a press if hydraulic pressure drops). Mobile Equipment: Used in agricultural machinery (e.g., tractor hydraulic lifts) or construction equipment (e.g., excavator arm hydraulics) to monitor and control hydraulic pressure during operation.
