HART375 smart handheld
|
?
| Product outline: |
| ? ??This wisdom expert holds suits in the HART agreement intelligent pressure transmitting instrument's communication operation, with HART275, HART375 is compatible, has the extremely good compatibility, but communication 1151,3351,3851, 1851, 3051, EJA and other HART agreement import measuring appliance, completely compatibly in domestically produced each kind of intelligent pressure transmitting instrument |
| Principle of work: |
?? The HART375 wisdom expert holds is one kind of portable terminal, it with uses the HART communication protocol the measuring appliance to use together, carries on the hypothesis to it, the change and the demonstration, it may monitor the input/value of exports and from the diagnosis result. Establishes the constant current the output and the zero alignment.
?
When the system starts or the maintenance operation, so long as the HART correspondence meets HART375 on the 4~20mA correspondence holding wire, may use. |
| Function characteristic: |
1st, online monitoring and correspondence
Correspondence period, the modulation signal will not interrupt 4~20mA the DC signal
2nd, with uses the HART communication protocol the measuring appliance to be possible to use in common
HART275 the HART correspondence can with use the HART communication protocol all measuring appliances to use together
3rd, ease of operation
The big screen (4 lines, each line of 18 characters), use Chinese to demonstrate that the user looked clear, the hypothesis and the change are convenient
4th, information from diagnosis/protection function
From inspection function
Formatting password protection
Low voltage warning demonstration |
| Technical parameter: |
Microprocessor 80MHZ
Built-in memory 32M?
System card 128M or higher working conditions - 10~50 degrees Celsius
