Brief introduction
ACD-201 Remote Digital Pressure Gauge increases the remote output communication module, which has RS485 communication, USB communication and 4-20mA signal output. This gauge can communicate with computer directly under the cooperation of communication software, which has data acquisition, storage and statements processing functions. This gauge adopts the signal isolation technique to eliminate interference. The lithium battery inside can work 5~10 years continuously. The gauge can still work stable without external power because of the build-in battery, but the communication function close without external power. It has radial direction, axial direction and panel mounting ways to choose.
