Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure

Pressure regulators are used to maintain a constant outlet pressure or flow

Pressure instruments are used to measure, monitor, record, transmit or control pressure

 Pressure vessels are storage tanks that are designed to operate at pressures above 15 psig

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only

Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line

Booster pumps are used in applications where the normal system pressure is low and needs to be increased

Pressure switches are actuated by a change in the pressure of a liquid or gas.  They activate electromechanical or solid-state switches upon reaching a specific pressure level

Pressure controllers accept input from pressure sensors, transmitters, gauges, and other devices and subsequently control adjustment to the pressure to maintain or achieve the desired pressure level

Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices

Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.

Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system

Reverse osmosis (RO) systems force water through a semi-permeable membrane to separate water from a solution of dissolved solids. Applying pressure to the solution causes water and other molecules with a low molecular weight to pass through the membrane

Pressure scanners allow the signal delivered to an instrument to be scanned or switched between multiple pressure sensors. Multi-channel pressure scanners increases the throughput and productivity of costly instrumentation

Specialty industrial process controllers are used in unlisted, specialized or proprietary applications.
