The PV70L14-15PZ is a pressure and vacuum switch primarily used in dust collectors and other filtration systems. Unlike the standard pressure transducer, this specific device is able to measure both absolute pressure and vacuum forces. Furthermore, it is equipped with three adjustable set points, which enable the users to easily control the operation range without particular instrumentation tools.

The main applications include milling, welding, and grinding processes, where the surrounding environment needs to be maintained at a certain pressure and vacuum level. Specifically, the switch is capable of controlling the fan rotation speed, the amount of surface particles, and dust collection efficiency to keep the environment at the desired level. Another common application is found in biogas production, where the PV70L14-15PZ can monitor the pressure and vacuum levels inside the fermenters and adjust the scavenging gas rate accordingly.

When exposed to the surrounding pressure or vacuum level, the PV70L14-15PZ will alter the electrical parameters and turn on or off accordingly. The inside mechanism comprises of a piezoresistive pressure transducer, a mounting base, and a switching chamber. As the pressure or vacuum level changes, the switching chamber will adjust accordingly and redistribute the pressure on the pressure transducer. This, in turn, will cause the electrical resistance inside the pressure transducer to vary, allowing the system microcontroller or computer to monitor the pressure level.

The PV70L14-15PZ is a highly versatile and reliable device, designed to operate in a broad variety of situations. It is easy to install and configure, making it a perfect choice for both industrial and residential settings. The three adjustable set points provide the users with a great flexibility in terms of monitoring and reacting to the environmental pressure and vacuum levels.
