Magnetostrictive level gauge

The main function

Output: output 4 ~ 20mA superimposed HART communication; Output two channels of 4~20mA, CH1 superimposed HART communication, CH2 without HART.

Diagnostic function: instrument fault, output alarm output current;

Dynamic variable monitoring function: liquid level value, percentage, output current, temperature, etc.

Current calibration function: analog output current can be calibrated;

User calibration function: 2 ~ 11 points can be selected for calibration;

Upper and lower limit calibration: two point calibration function, realize zero and full degree fine tuning;

Fixed point fine tuning: carry out any point migration to achieve translation function;

Local configuration function: for engineering unit, range, damping, alarm upper and lower limits, bottom offset, display variable, magnet polarity, signal amplitude, dead zone, first and second float interval and working mode configuration and data recovery function;

Local calibration function: local upper and lower limit calibration, fixed point fine tuning;

LCD display function: multi-functional digital LCD display with backlight; Various engineering units can be displayed.

Communication function: communication function conforming to H ART protocol;

Data backup and recovery: the manufacturer backs up the original information of the manufacturer after the configuration and calibration of the instrument. If the instrument cannot work properly due to the illegal adjustment by the user on site, the manufacturer's factory information can be transferred by the field input or remote instruction, and the illegal error information of the user can be overwritten to achieve the normal working state
