Different Types Of Pressure Switches

Pressure switches are considered to be one of the most common devices in industrial applications these days. if you’re wondering about what a pressure switch is, in its simplest form, a pressure switch is a device that can detect a pressure change and, at a predetermined level, opening or closing an electrical contact. In its most basic form, the modern pressure switch has two basic elements: a pressure sensor and a switch contact.. Whenever the process pressure reaches a certain value, called the switch point, the switch contact actuates and either allows or stops current from flowing in the control circuit.

Pressure switches usually fall under three basic classifications: electromechanical, solid-state and electronic. If one has to talk about the normal scenario, then pressure switches have been electromechanical devices. the following types of switches are elucidated below: 

Electromechanical Pressure Switches

These are the most common types of pressure switches. They are composed of a sensing element and an electrical snap-action switch. Sensing elements have one thing in common; They move in response to the changes in the system pressure. However, differential pressure switches are a little different. In their cases, there are two pressure ports, one for the low-pressure side and the other for the high-pressure side. The low pressure and high-pressure fluids act on the same sensing element. Since the surface areas are equal on each side, the switch is in equilibrium when the pressures are equal. As pressure on the high-pressure side increases, or pressure on the low side decreases, the piston moves up and, at a preset differential pressure, activates the snap switch. Switches are grouped based on the sensor technology employed in them. 

Solid-state pressure switches

 The first solid-state pressure switch was introduced by Barksdale in 1980.  It was a very simplified device that combined a bonded strain gage sensor and triac switch. Today, there are a wide variety of solid-state pressure switches that have one to four or more switch points, digital displays, analogue and digital outputs, and full programmability. Hence, technology has transformed it into a switch that is much more modern. 

Electric Dual Pressure Switch

This pressure switch has some truly impressive attributes. This switch represents the next step in the evolution of pressure switches and also bears a lot of interesting qualities.
