Introduction

HRT-370 is a HART signal filter specially designed to solve the issue that analog signal gets interfered while additional HART signal adding to communication process. When connecting HRT-370 to a HART instrument, it splits the input HART signal to two output channels, one keeps the original HART signal and another filter the HART signal out to output pure analog signal. Therefore, users can make both HART and analog current data collection and processing easier and more precise by applying HRT-370.
