Category

PW219 series pressure switches is a measurement and control component integrating pressure measurement and control. This series of products mainly use silicon piezoresistive pressure sensors as the pressure sensitive core, and can also be equipped with pressure sensors such as ceramic capacitors, sapphire, and sputtering films. After programmable digital circuit correction and signal conditioning, they can output standard industrial application signals and switches. quantity signal. Depending on the mode of use, the product can output 1 to 4 sets of switching signals, which can control up to 4 pressure points. Customers can freely set the switch point according to their needs.

PW219 series pressure switch faithfully serves various fluid measurement industries with its excellent performance. Especially in water treatment, power, medicine, and other industries, it has good adaptability and application advantages.
