An Introduction to Field Communicator

- Jun 27, 2019-

A handheld field communicator (also intelligent or smart communicator) can automatically connect the given signal of the system or regulator and the feedback signal of the valve position, adjust according to the deviation of the two and output the corresponding value. It can directly actuates the valve and can be connected to various regulators or computer control systems and used as a backup gauge.

 

Features

Automatic calibration and manual calibration are available in one communicator. Undisturbed switching from automatic to manual calibration can be realized.
The intelligent operator can be equipped with one analog control output and one switch control output respectively; relay forward rotation, reverse rotation control and one analog output, suitable for various measurement control occasions.
Multiple protection and isolation designs with strong disturbance resistance ability and high reliability.
Good software platform with secondary capabilities to accomplish  specialized tasks.
Advanced module structure, with powerful instrument chip, convenient to make functional combination and upgrade system.

 

Hart Communicator

Communicator is a portable instrumentation terminal that is used with instruments that use the HART communication protocol to set, change, and display monitor input, output values, and self-diagnosis results. Set the output and zero of constant current. When the system is on for operation or maintenance operation, the HART communicator can be used by connecting it to the 4~20mA communication signal line.

 

Distinction

The intelligent communicator is a digital display. It is used to automatically connect the given signal of the system (or regulator) and the feedback signal of the valve position. It adjusts according to the deviation of the two, and outputs the corresponding control. It can take replace of the small power amplifier to directly actuate the valve, and can be connected to various regulators or computer control systems and used as a backup instrument.

HART Communicator is a handheld communicator supporting HART protocol equipment, mainly used for industrial site configuration, management, maintenance, adjustment of HART smart meters and monitoring of process variables in the process of operation. Competitive function, low price and good compatibility. Support all standard HART communication instruments, and generally it’s used together with the transmitter.
