Product Overview:
This intelligentHARTCommunication operation of intelligent pressure transmitters suitable for HART protocol, with HART275, HART375 compatible, with excellent compatibility, can communicate with imported instruments of 115133513851, 1851, 3051, EJA and other HART protocols, fully compatible with various domestic intelligent pressure transmitters
working principle:
HART375 IntelligentHARTIt is a portable terminal that is used in conjunction with instruments that use the HART communication protocol to set, modify, and display input/output values and self diagnostic results. Set constant current output and zero.
When the system is started or maintained, simply connect the HART375 HART communicator to the 4-20mA communication signal line to use it.
Functional features:
1. Online monitoring and communication
During communication, the modulation signal will not interrupt the 4-20mA DC signal
2. Can be shared with instruments that use the HART communication protocol
The HART275 HART communicator can be used with all instruments that use the HART communication protocol
3. Easy to operate
Large display screen (4 lines, 18 characters per line), displayed in Chinese, easy for users to see at a glance, and convenient for setting and changing
4. Information self diagnosis/protection function
Self checking function
Format password protection
Low voltage alarm display
