OVERVIEW
The HUTD-Z series intelligent electric float liquid level (interface) transmitter adopts microprocessor technology to output 4-20mA analog signals and digital signals that comply with the HART communication protocol superimposed on this signal.
The smart transmitter should be equipped with a handheld programmer that can be networked with all devices that comply with the HART protocol to achieve digital bidirectional communication and process detection and control.
MAJOR FUNCTION
Use a handheld programmer and other devices that comply with the HART communication protocol to perform the following operations on the smart transmitter on-site and remotely:
Read process variables such as raw variable values, mA values, percentage ranges, etc
Zero and range settings: Adjust with a manual controller or use a transmitter to adjust zero and full range
Read diagnostic information: Diagnostic information includes: parameter settings too high or too low; Exceeding the measurement range; 4-20mA exceeds the range, etc
HART communication command: Use a handheld device or other equipment to communicate with an intelligent transmitter, and read PV values and currents on the display screen
