G1/4 Variable Frequency Pump Pressure Sensor — 1.2MPa, DC 5V Designed for reliable pressure feedback in variable frequency pump systems and wallmounted boilers. This compact pressure sensor provides a standard G1/4 threaded connection, supports liquids and gases, and operates from a DC 5V supply for easy integration into control systems. Key benefits Precise pressure feedback for control: Enables closedloop control of variable frequency pumps and maintains stable system pressure in heating, water supply, and gas systems. Easy integration: Standard G1/4 mechanical connection and DC 5V electrical supply allow direct replacement or addition to existing control loops and boiler systems. Versatile medium compatibility: Rated for use with water and gas, making it suitable for boiler pressure monitoring, water circulation, and gas pressure detection. Compact, applicationfocused design: Tailored for wallmounted boilers and pump control panels where space and reliable feedback matter. Main features and attributes Pressure range: 1.2MPa maximum working pressure. Thread type: G1/4 standard threaded connection for straightforward plumbing installation. Power: DC 5V supply for lowvoltage system compatibility. Application focus: Designed for variable frequency pump (VFD) systems and wallmounted boiler installations. Media: Suitable for use with water and gas. How it solves problems Stabilizes pump operation: By providing continuous pressure feedback to the pump controller, it helps the variable frequency pump adjust speed to meet demand, reducing cycling and energy use. Protects boiler and system components: Early detection of pressure deviations allows automated systems to respond before faults escalate. Simplifies retrofits: Standard mechanical and electrical interfaces reduce installation time and the need for custom adapters. Compatibility and installation notes Mechanical: Installs via standard G1/4 threaded port. Verify mating thread and sealing method (e.g., sealing tape or appropriate gasket) before installation. Electrical: Requires DC 5V supply from the control system. Confirm controller input compatibility and correct wiring during installation. System integration: Intended for use as a pressure feedback sensor in variable frequency pump control loops and wallmounted boiler pressure monitoring. Confirm controller input type and any signal conditioning required by your control hardware. Typical use cases 1) Wallmounted boiler pressure monitoring — Install the sensor on the boiler pressure port to provide realtime pressure feedback to the boiler controller, enabling safe operation and automatic pressure regulation. 2) Variable frequency pump control in circulation systems — Use the sensor as the pressure feedback element for a VFD pump drive to maintain consistent delivery pressure in domestic hot water or closedloop heating systems. 3) Water and gas line monitoring — Monitor supply pressure in compact installations where a G1/4 connection and DC 5V power are required. Practical considerations Ensure compatibility of controller input and wiring with a DC 5V powered sensor. Confirm that the sensor media (water or gas) are compatible with the system's pressure limits and operating conditions up to 1.2MPa. Use appropriate sealing and mounting practices for G1/4 connections to prevent leaks.
