We are Offering All Well-Known Brand of Pressure Switch and Spare Parts for It.
Pressure is defined as the physical force exerted on an object. the force applied is perpendicular to the surface of objects per unit area. the basic formula for pressure is f/a (force per unit area). unit of pressure is pascals (pa).
Types of pressures Absolute-Atmospheric-Differential-Gauge Pressure
The most commonly measured pressure in the technical field is the atmospheric pressure differential, it is the difference between an absolute pressure, pabs, and the relevant (absolute) atmospheric pressure and is known, in short, as the overpressure or gauge pressure.
The Earth’s Atmospheric Air is surrounded by a Layer of Gases and so This air surrounding the earth exerts a pressure known as the ‘atmospheric pressure’. its value at sea level is 101325 pa.
It is measured using a mercury barometer (hence atmospheric pressure is also known as barometric pressure), indicating the height of a column of mercury which exactly balances the weight of the column of atmosphere over the barometer. it can be expressed inseveral different systems of units such as millimeters (or inches) of mercury, pounds per square inch (psi), dynes per square centimeter, millibars (mb), standard atmospheres, or kilopascals.
The Atmospheric Pressure Decreases Near Earth’s Surface, with height at a rate of about 3.5 millibars for every 30 meters (100 feet).
A pressure switch is a form of switch that operates an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids.
Another type of switch detects mechanical force; for example, a pressure-sensitive mat is used to automatically open doors on commercial buildings. Such sensors are also used in security alarm applications such as pressure sensitive floors.
There are two main types of pressure switches:
-Mechanical (electromechanical) Electromechanical pressure switches employ several types of sensors.
-Electronic (solid state)
A switch is usually adjustable with regard to the chosen set point of operation. Also known as pressure sensors, they are used to respond to fluid pressure. For example, a pneumatic switch in compressors and pumps, or hydraulic switches in automotive engineering.

switches rely on water pressure to do all the work. The change in pressure that activates the switch is provided via the water from the well. The pressure moves up through the diaphragm which presses against a piston and spring, which in turn opens or closes the contacts. Open contacts located within the switch, closes when pressure drops. This completes an electrical circuit, which in turn activates the pump. When the set pressure is reached, this allows the contacts to open again which turns off the pump. switches are usually wired to a control box. If you have any questions about switches or if you’re in need of a replacement, you can send us your request. A switch is a simple electromechanical device that is triggered by pressure to turn an electrical circuit on or off
switches are one of the most common measuring devices used in industrial applications today, found in pumps, HVAC equipment, and hydraulic systems. These devices ensure processes have enough pressure to operate properly. In its most basic form, the modern switch has two components: 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. There are two main types of switches Mechanical (electromechanical) Electronic (solid state) switches are widely used for a large range of applications throughout industry and manufacturing. Their function is to provide systems with electrical feedback in response to measuring a rise or fall in pressure. A switch is usually adjustable with regard to the chosen set point of operation
