HART 770 with display Magnetostrictive Level Transmitte



 APPLICATION         

       H770KM: HART main board with green backlight LCD.

       H770KB: Signal processing board, there a red plastic parts on it
 

Used for magnetostrictive level meter 

           Power supply:  12-32VDC

           Output:  4~20mA with HART (2-wire)

           Resolution: 0.3 mm

           Accuracy: 1 mm 

           Operating temperature: a

                   -20°C ~ +70°C(with LCD)

                   -40°C ~ +85°C(without LCD)

           Dimension: diameter Φ= 62 mm

                  Mounting hole pitch D=55 mm 

Features:

•   Easy Assembly: Easier to install and to recognize coaxial sensor signal.
•   Powerful self-test function: Through software, users can detect the magnet polarity, signal amplitude and evaluate without using an oscilloscope.
•   Support dual float: Two-channel isolated 4 ~ 20mA signal outputs. The first channel is for the first float level or level difference and the second channel is for the second float level.
•   Strong capability for anti-disturbance:  Leading military-grade hardware and software anti-disturbance technology, over-voltage protection, surge current, electrostatic shock and lightning protection.
•   Multiple local operation functions: Range Values, PV Unit, Damp, High Alarm Value,  Low Alarm Value, Zero Trim, Lower Sensor Trim and Upper Sensor Trim , Magnet Polarity, Signal amplitude, Dead zone and Data Restore.
•   LCD display: 360^orotation LCD display. More than one variable displayed on the LCD with backlight for dark environment.
•   Data backup and restore.
