Specifications. The specifications of the pressure switch include the following. The range is -1 to 250 Bar. Contact rating is 5a, 10a, 15a at 250/125 Vacs. The process connection is ¼”,½”, ¾”, 3/8” Bsp or npt Threaded (m/f). Switch type is 1spdt

A pressure switch is an air-electric signal changer. Load switches are applied to interact with a variation in pressure, and it will open or close an electrical 

Sensors for air and non-combustible compatible gases have an electrical contact output at a specific difference between two pressures. Applications vary between the different types of differential pressure switches. A wide variety of switches and circuit styles enables control functions needed for any system.

The switch has either a preset or an individually, mechanically adjustable switch point. Each time the switch is actuated, a mechanical pressure switch sends an electrical switching signal, but does not require a voltage supply. Ordinarily, mechanical pressure switches are simple devices that are either designed for cost-effective applications

5/22 · 22 May , News. A pressure switch is a device designed to give an output in response to a set level of pressure. The switch makes electrical feedback on the rise or fall

Attach the ground wire to the green ground screw. Attach the power supply from the main breaker to the outside terminals marked "Line" (L1/L2). Attach the ground wire to the green ground screw. Re-install the switch cover and reconnect the power. Test the pressure switch for several cycles to ensure that it is working properly.

3/30 · Briefly stated, a pressure switch is an instrument that measures pressure and that has an electrical switch function programmed to operate at a certain pressure. For example, it can be set so that when no pressure is connected (open to atmosphere) the switch is closed, but when pressure increases up to 10 psi, the switch opens.

An electro-mechanical pressure switch works by applying pressure to either a diaphragm, bellow or a piston to exert motion. The motion can create electrical 

There are vacuum, differential, and positive pressure switches that can be used with air, water, and oil in temperatures ranging from -40 to 120 C. These switches are made-to-order allowing us to offer a vast array of threads and electrical connectors to suit your needs.

The Tire Pressure Monitoring System (TPMS) is a safety device that measures, identifies and warns you when one or more of your tires is significantly under-inflated. Standard® and Intermotor® are committed to helping technicians with TPMS repairs, whether it's offering OE-Match TPMS sensors or providing repair tips from our team of ASE-certified master technicians. Here are a few TPMS

A pressure switch is a mechanical device that relies on air pressure to control the operation of an electric air compressor. This simple mechanism completes the circuit and allows power to the motor as long as system pressure is below a specified setting.

Pressure switches are generally used in industrial and automotive applications, where there is a requirement to produce an electrical signal once a certain

A pressure switch is used to detect the presence of fluid pressure. Most pressure switches use a diaphragm or bellow as the sensing element. The movement of this sensing element is used to actuate one or more switch contacts to indicate an alarm or initiate a control action. Pressure switches have different designs with different sensing elements.

A pressure switch is simply a device capable of detecting a pressure change and, at a predetermined pressure, opening or closing an electrical switch. Pressure switches are usually classified as either electromechanical or solid state. Electromechanical pressure switches have a sensing element which responds to changes in pressure and

The electrical contact of a pressure switch is typically NC (Normally Closed), NO (Normally Open), or changeover. Changeover means that the common terminal switches between two contacts, allowing the switch to be used in either NC or NO operation. Changeover contacts are also referred to as SPDT (Single Pole Double Throw).
