Explosion-proof electronic digital differential pressure sensor PN-533

Product introduction

The PN-533 uses a diffuse silicon sensor to measure pressure, and the signal is processed by post-processing circuitry to convert the signal into a standard industrial electrical signal for output and display.
The all-metal housing and bright LED digital display allow the PN-533 to be used in a variety of industrial applications. The two-button design and menu make the product easy to use, and a variety of connection options are available to meet specific installation requirements.
