1、 Product Introduction

The ZRN series pressure sensor adopts a high-sensitivity pressure core body, which is fully welded and packaged in a stainless steel shell. It has the characteristics of high accuracy, low hysteresis, large output signal, and long working life. At the same time, it has three types for users to choose from: absolute pressure, sealed reference pressure, and vent gauge pressure. Suitable for pressure measurement of various dynamic, static, and general corrosive gases and liquids.
