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

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

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

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

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

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

Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms

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

Pump controllers monitor flow and/or level variables, and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off, or more advanced controls for pump speed, output pressure, etc

Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values

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

Boiler controllers monitor and maintain variables such as steam temperature and pressure in order to control a boiler’s burner or air mixture

Level controllers monitor, regulate, and control liquid or solid levels in a process.

Environmental controllers control environmental factors such as temperature, humidity, and air pressure. The environment to control can be an office or workspace, or inside a chamber for testing or process purposes

Vacuum controllers monitor and control vacuum levels for process equipment such as vacuum furnaces, autoclaves, and coating machines
