Pressure Switches

Pressure Switches

An adjustable pressure switch is just one in a line of pressure controls. An adjustable pressure switch is a simple mechanism that converts an applied pressure through a process connection into a current or voltage output. Switches have a current (4 to 20 mA) output or voltage (VAC or VDC) output. Davis Instruments has a wide range of transmitters and transducers from which to choose. We carry standard switches as well as industrial switches. Industrial switches will have a very durable case to protect the electronics of the unit and even will have explosion cases for many applications, such as in oil and gas exploration and extraction. When not in a very dangerous industrial process, most switches will have a stainless steel case to protect the unit from mild acids and slightly caustic applications. All switches are used for their output to control pumps, switches, PLCs, or just send a signal to a panel meter to control processes or signal need for attention. Many switches are non-electrical and will have a mechanical set point that will shut off flow of air, gases, or liquids when the set point is reached. If you have questions about selecting an adjustable pressure switch contact a Davis Application Specialist.
