PVS20-5,00, which stands for pressure vacuum switches, is a device used for testing the pressure of a substance or medium. It is designed to detect changes in the pressure of a system and then take appropriate action. The device is used primarily in industrial settings as an adjustable safety feature to prevent machine overpressure or underpressure.

A PVS20-5,00 switch is typically composed of a sealed enclosure with two pressure sensors, one on the bottom and one on the top. Each sensor is sensitive to a specific range of pressure and is calibrated depending on its application. The enclosure also contains a control circuit which is used to detect a change in pressure from the sensors, and then take the appropriate action. When the difference between the two sensors measure outside of the calibrated range, the control circuit either turns a valve to reduce the pressure or deactivates an alarm if the pressure is too high.

Depending on the application, PVS20-5,00 switches may respond to barometric pressure, vacuum, absolute pressure, or differential pressure. Generally, barometric pressure switches are used to monitor atmospheric pressure, while absolute and vacuum pressure switches are typically applied in enclosed enclosures, such as computer and electronic equipment, where a specific pressure needs to be maintained or controlled. Differential pressure switches are used mostly when two fluids need to be kept isolated from one another and it is important to monitor their pressure differences.

Another application of PVS20-5,00 is in vacuum systems, which uses the switch for testing and monitoring the pressure at different points in the system. Here, the device can detect fluctuations in pressure and activate a warning system or a shut-down system if required. Vacuum systems are usually used in a laboratory setting, and the switch works in tandem with other components, such as pumps and filters, to maintain optimal conditions.

The working principle behind PVS20-5,00 is simple. Its control circuits work as a comparator, measuring the difference between the two pressure sensors, and then activating the alarm or valve when the difference is beyond the calibrated range. The sensors measure the pressure and convert it into a signal, which is then sent to the control circuit. The control circuit then compares the pressure signal to the set pressure range, and then takes the appropriate action.

In summary, PVS20-5,00 pressure switches are used primarily in industrial settings for detecting changes in pressure in a system. These changes are detected by the device\'s two pressure sensors and then the control circuit acts appropriately. Different types of PVS20-5,00 switches are designed for monitoring barometric, absolute, vacuum, and differential pressures. Their working principle is based on comparing the difference between the two sensors, and then taking the necessary action when the pressure range is exceeded.
