Pressure gauges are used to display, monitor, measure, maintain and control pressure for pipe lines, tanks and pressure containers, strainers, filters, valves, pumps, regulators and separators. Available pressure gauges are manufactured in the USA by Hayward Industries, Inc. Available pressure gauges are suited for use in liquid, gas or air handling applications. Hayward® brand gauges are designed for use in corrosive environments and those that experience high vibration and pressure spikes. Our pressure gauges are engineered for use in pressurized plumbing systems to measure positive pressure forces and fluctuations only. They are not intended for use in vacuum type, negative pressure force applications. Hayward® brand gauge guards are suitable for use in either positive or negative pressure scenarios. The pressure gauge is a common accessory to applications within water and wastewater treatment, the production, transfer and processing of chemicals, aquariums, aquatic and animal life support systems, water parks and pools, marine and maritime work use scenarios, environmental monitoring and maintenance as well as general industrial and manufacturing applications.
All Hayward® pressure gauges offer high accuracy with certified calibration results. Accuracy range depends on gauge series model. We offer analog and digital pressure gauges in simple to install models. All analog pressure gauges come factory prefilled and vacuum sealed with no assembly or filling required, removing difficulties associated with self-fill gauge models. Analog gauges feature glycerin filling with silicone filling option available on request. In the analog model pressure gauge, read out displays are an easy to read 2 1/2" face behind a safety glass lens with large, colored numbers in red and black fitted along a 270° arc dual marked in PSI / BAR unit scales. Analog gauge features green, yellow and red movable pointers fitted to the bevel for use in system monitoring and maintenance. Measuring principles are 316 SS bourdon tubes with a chemically durable diaphragm.
Digital pressure gauges feature an LED display with color changing numbers for alarm alerts and easy visual monitoring of maintenance conditions. Digital gauges come with a large, 2 1/2" heavy duty pressure display and isolator for chemicals and aggressive fluid applications. Digital gauges are adjustable and programmable with variable relay alarm outputs, ranges and pressure units. They feature 4 – 20 mA analog output ports for remote displays. No programming, filling or assembly is required.
Important features and specifications are outlined below based on offered Hayward® pressure gauge series models:
Max working temperatures are 170°F (76°C) for PP gauges and 195°F (90°C) for PVDF gauges. For GD Series, working temperature ranges are -4°F to 176°F (-20°C to 80°C).
