Pressure switches are warning devices that are used for a variety of applications in a number of different industries. These switches help to detect hazardous changes in pressure and initiate a safety warning as well. Pressure switches can also alter elements within the system or sound an alarm to bring the situation under control.
Most switches are designed to adjust, close or open an internal contact that is based on a previously programmed level or point of functioning. There are two main kinds of pressure switch available today that are being used in different industries.
Solid state pressure switches- These pressure switches have digital and analog features and can be fully programmed. Solid state pressure switches can also have more than one switch point and digital displays. They offer a number of advantages, with the main one being their long operational life which is about 100 million cycles. Apart from this, other advantages include a high resistance to vibration and external shock, durability, high rates of accuracy, adaptability to several ranging system pressures, vast range of frequency response and enduring stability.
Electromechanical pressure switches- The pressure switch usually has an electronic snap-action attached to the sensory elements. Regardless of the type of element, these pressure switches never fail to react to the pressure of the system. Snap-action switches close or open contacts based on the lows or highs identified by these electromechanical pressure switches.
For decades, electromechanical pressure switches were the only kind used in different industries. However, the introduction and advantages of solid state pressure switches have made them more popular today.
