1. Brief introduction

Huakong HK-H***1R metal capacitance HART board is designed in conformity with HART protocol. With HART communication, customers could manage and adjust the HART instrument and meantime monitor the process variables.

It is widely used in manufacturing ***1 metal capacitance transmitters, and it has high accuracy and stable output.

The HK-H***1R capacitance pressure board is consisted of HK-H****-CPU, HK-H***1R-AD and HK-H***1R-LCD
