Bộ truyền thông HART cầm tay, HART Communicator HART475,HART375,HART388,HART275 Handheld Communicator

The hart475 Communicator is an upgraded version of the HART375 Communicator that works with meters that use the HART communication protocol to set, change, and display it to monitor input/output values ​​and self-diagnosis results. Set the output and zero of constant current. When the system is started or maintained, the HART communicator can be used by connecting it to the 4~20mA communication signal line.

 
   This communicator is suitable for communication operation of HART protocol intelligent transmitter. It is compatible with HART275, HART375 and HART475 handheld communicators . It has excellent compatibility and can be used to import imported instruments of 1151, 3051 , EJA, ABB and other HART protocols. It is compatible with all kinds of intelligent pressure (temperature) transmitters made in China. At the same time, it can communicate with the flowmeters that support HART protocol, such as electromagnetic flowmeter, V-cone flowmeter, target flowmeter, vortex flowmeter.
 
Features:
■ During the online monitoring and communication communication, the modulation signal will not interrupt the 4~20mA DC signal.
■ It can be shared with the instrument adopting the HART communication protocol. The HART communicator can be used together with all instruments adopting the HART communication protocol.
■ Convenient operation and large display screen (4 lines, 18 characters per line), displayed in Chinese, the user can see at a glance, easy to set and change
■ Information self-diagnosis / protection function
 
● Full-featured communication: communication support flow meter with HART protocol, temperature meter, change Transmitter
