Pressure Switches
Pressure switches are essential components that monitor and control pressure levels in a variety of industrial and commercial applications. They can be either a mechanical or electronic device. Each type serves specific needs depending on the sorts of pressure they're tasked to handle, the process fluid, and the environment in which they're placed. Mechanical pressure switches usually control straightforward pressure applications. If your equipment isn't trying to do something very complicated with its pressure control, mechanical pressure switches should have you covered. Conversely, if you do have a complicated application, these switches likely have some manner of digital output that communicates what they're doing.
Pressure switches are available in many forms, low-pressure switches for more sensitive systems and the high-pressure switches for tougher applications. And then there are the adjustable pressure switches, which let you set the pressure threshold to whatever fits your particular application. If those applications happen to be in hazardous or explosive environments, then you would use an explosion-proof switch. Other pressure switches include: electronic pressure switches, mechanical pressure switches, differential pressure switches, hydraulic pressure switches, diaphragm pressure switches, oil pressure switches, air pressure switches and gas pressure switches.
