0-250 psi Water Pressure Gauge

The 0-250 psi water pressure gauge is an industrial-grade measuring instrument specifically designed for measuring water medium pressure. It covers a range of 0 to 250 pounds per square inch (psi), which is equivalent to approximately 0 to 1.72 megapascals (MPa) in metric units. Its core function is to conduct real-time and accurate monitoring of water pressure changes within pipelines or equipment, providing data support for the safe operation and pressure regulation of fluid systems. With advantages of wide range adaptability, accurate measurement, and durable structure, this water pressure gauge is a commonly used instrument in water medium pressure monitoring scenarios. It can effectively ensure the pressure stability of fluid systems and reduce safety risks and equipment failures caused by abnormal pressure.

Product Formation

The 0-250psi water pressure gauge is a mechanical pointer pressure instrument specially designed for water system pressure monitoring. It senses water pressure changes via a Bourdon Tube, driving the pointer to display real-time pressure values within the 0-250psi (≈0-1.72MPa) range. Combining high-precision measurement, water corrosion resistance, and long-term stability, it serves as a core pressure measurement component for "real-time monitoring and safety early warning" in fire sprinkler systems, building water supply/drainage, HVAC systems, and industrial circulating water systems.

Its development process integrates precision mechanical design, corrosion-resistant material selection, and full-process quality control—ensuring accurate, reliable operation in complex water environments and providing critical data support for system operation and maintenance.

The gauge achieves its core functions of "precise pressure measurement, water-resistant durability, and clear reading" through:

A structural design combining phosphor bronze Bourdon tube sensing, precision gear transmission, and a fully sealed case;

A manufacturing process integrating cold bending forming, laser welding, and standard calibration.

Its material selection (phosphor bronze / PA66+GF30), performance testing (precision, pressure resistance, vibration), and certification standards (GB, ASME, IP65) are all centered around long-term stable monitoring of water systems—making it an indispensable pressure monitoring component in civil and industrial water applications.

Product Features

Precision Assurance: Indication error ≤±3%FS (full scale), with the scale densified to 0.5psi in the critical range (0-100psi) for real-time early warning of abnormal pressure.
Visual Design: White dial paired with black laser-engraved scales, a red luminous pointer (visible for ≥8 hours in -20℃~70℃ environments), and a zero-adjustment knob with micro-adjustment error ≤±1psi—enabling accurate reading even at night or in low light.
Dust & Water Resistance: Fully sealed arc-shaped case with front tempered glass (3mm thick, impact resistance ≥5J), IP65 protection rating—resisting low-pressure water jet flushing and dust intrusion.
Wide Temperature Tolerance: Indication drift ≤±1%FS in -20℃~70℃ environments, adapting to regional climate differences and outdoor installation.
Quick Assembly: Nickel-plated thread surface for rust prevention, high interface compatibility, and single-unit installation time ≤5 minutes—ideal for emergency deployment in fire sprinkler or water supply/drainage systems.
High Versatility: Adaptable to multiple application scenarios, delivering strong flexibility for diverse needs.
