Pressure Switch Suppliers: Types of Pressure Switch Explained

The Pressure Switch Family

Pressure switches are often classified as part of the Pressure Sensor category, depending on the source. These devices are essential for measuring the pressure of gases and liquids. Alongside pressure switches, this category also encompasses pressure transducers, pressure transmitters, and other similar devices. This overlap can create confusion in the fields of instrumentation and process control. Generally, a sensor is defined as a device that identifies changes in physical, electrical, or chemical properties and generates an electrical output. To complicate matters further, the terms pressure sensor, pressure transducer, and pressure transmitter are frequently used interchangeably in industrial contexts.

Explore here different kinds of switches that you can avail from a PRESSURE SWITCHES SUPPLIERS IN UK and get to know how they operate.

What is a Pressure Switch?

A pressure switch is composed of two main components: a sensing transducer and an electrical switch. The electrical switch is designed to open and close at a predetermined pressure, commonly known as the Setpoint. Depending on the manufacturer and model, this switching pressure can either be fixed or adjustable. The transducer itself is a device that transforms one type of energy into another, and it is the component that interacts directly with the process being monitored. It is essential for the transducer to effectively trigger the operation of the electrical switch.

PRESSURE SWITCHES SUPPLIERS IN THE UK manufacture pressure switches utilizing various types of transducers and switches. While both pressure transmitters and pressure switches incorporate transducers, they differ significantly in function. A pressure transmitter generates an analog electrical voltage as its output, marking a clear distinction between the two devices.

Electromechanical pressure switches utilize conventional mechanical components, featuring moving parts that are integral to their operation. When seeking a diverse range of transducers, you can rely on reputable PRESSURE SWITCHES SUPPLIERS to provide options like diaphragm and Bourdon types, which are essential for the mechanical activation of these switches.

Diaphragm switches function by utilizing a metal diaphragm to activate the switch mechanism. In contrast, Bourdon type switches rely on a bourdon tube to perform the same task. Solid state pressure switches are designed without any moving components. They achieve electrical switching through the activation of semiconductor devices, such as bipolar junction transistors or field effect transistors.

The phrase electronic pressure switch is gradually taking the place of Solid State Pressure Switch. While the electronic pressure switch is indeed solid state, it brings a level of versatility that is unmatched. This advanced device features programmable functions, LED displays, and a variety of adjustable output switch configurations, including normally open, normally closed, or even both options.
