Dial Differential Pressure Gauges

Available37 products

Dial differential pressure gauges measure the difference in pressure between two points in a system and display the measurement on an analog dial display. Users can connect gauges with integral switches to a control system to respond when the measured pressure rises or falls below a set point. Gauges are available for use in low-, medium-, and high-pressure systems.

For Low Operating Pressure

For Low Operating Pressure

These gauges are designed for use with lower total static system pressure. They measure and indicate differential pressure of air and compatible gases or liquids. The gauges are commonly used for reading pressure in isolation and hospital environments and temporary units.

Gauge with Switch For Low Operating Pressure

Gauge with Switch For Low Operating Pressure

These gauges are used for applications with lower total static system pressure and measure positive or negative differential pressure of air and compatible gases. Also called differential pressure switches, these gauges both measure and control differential pressure or negative or positive static pressure of air and compatible gases, allowing monitoring and switching to be performed by a single instrument. Common applications include clean rooms and glove boxes, lab exhaust systems, and air conditioning.

For Medium & High Operating Pressure

For Medium & High Operating Pressure

These dial gauges measure the pressure difference between two points in medium- and high-operating pressure systems. Gauges with diaphragm actuators permit no bypass of fluid and can be used on air, gas, and liquids in applications such as water treatment and anhydrous ammonia. Gauges with piston-style actuators, which can permit fluid migration, are used in demanding applications such as hydraulics, pumps, and heat exchangers.
