ABUSTEK  make  Pressure Transmitters  Hart CommunicatorHART Hand Held Communicator is a hand held interface based on HART protocol, which can perform configuration, management, maintenance and adjustment to all HART compatible instruments. It can be easily connected into 4~20mA loop, to achieve the configuration of instrument parameters (upper limit and lower limit etc.),the reading of instrument variables, as well as the diagnosis and maintenance of the instrument. This Communicator can support not only the HART main device (HART multiplexer etc.), but also the peer-to-peer and multi-drop HART communication modes.
