0.075% Accuracy RS485 Protocol Pressure Transmitter
0.075% Accuracy RS485 Protocol Pressure Transmitter Description:
0.075% Accuracy RS485 Protocol Pressure Transmitter is an
intelligent field
instrument in accordance with RS485 protocol. The original imported
diaphragm is designed with a
microprocessor and a RS485 communication circuit. It can
communicate bidirectional with any host
computer software supporting RS485 communication protocol or
268,275 hand-operated devices
that conform to RS485 communication protocol. With 5 bits
intelligent digital liquid crystal display,
the differential pressure / pressure value, output current value
and output percentage value can be
displayed on the spot. The debugging is very convenient, and the
digital and intelligent functions of
the transmitter are realized. And with the traditional simulation
input The output signal is
compatible so that the exchange with the analog table can be
achieved without changing the control
system.
