Shop Dwyer Differential Pressure


Pressure, flow and piston-type gages are all found within this category. Clean design, small size and low cost with enough accuracy for all but the most demanding applications, these gages are the best around. Gages are indicators for the difference between two pressures or simply a single pressure.

Gage / Switches - Dial

Dial Gages and Switches are compatible with air and other non-combustible and non-corrosive gases. Dial Gages and Dial Switches are indicators for the difference between two pressures that also have switch outputs. They can also be used for single pressure.

Gage / Switches - Digital

Digital indicators are for the difference between two pressures. The Gages and Switches are ideal for pressure, velocity, flow applications and single pressure. Products have Modbus communications and are 3 in 1 instruments. With features packed into 1 product, the Digihelic® controller is the only instrument for your pressure applications.


Sensors for air and non-combustible compatible gases have an electrical contact output at a specific difference between two pressures. Applications vary between the different types of differential pressure switches. A wide variety of switches and circuit styles enables control functions needed for any system.


Transmitters are sensors with an electrical transmission output for indication of a difference between two pressures. They are designed for use with compatible gases and liquids applied to the pressure and reference ports.

Data Loggers

Data loggers save readings for the difference between two pressures over time. Ideal for monitoring air duct velocity, testing and balancing HVAC systems, or verifying room pressure. Loggers can store up to 21500 readings and operate independently from external power supply.
