APPLICATION
HK series of products are mainly used in applications of two-wire
signal and HART transmission, to solve a series of problems due to
the ground potential difference during the transmission application
of them caused by different ground loops, such as, the signal
transmission errors around 4~20mA, followed by the interruption of
HART communication or damage to equipment port device. HK
series adopts the loop way to take power, and compensates
transmission errors caused by electric potential difference, so as to
ensure the accuracy of the communication transmission.
