FEATURES
Ø Assembly: Easier to install and to recognize coaxial sensor signal.
Ø Powerful self-test function: Through software, users can detect the magnet polarity, signal amplitude without using an oscilloscope.
Ø 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.
Ø Strong capability for anti-disturbance: Leading military-grade hardware and software anti-disturbance technology, over-voltage protection, surge current, electrostatic shock and lightning protection.
Ø Multiple field adjust functions: Range, PV Unit, Damp, High Alarm, Low Alarm, Zero Trim, Lower Sensor Trim and Upper Sensor Trim , Magnet Polarity, Signal amplitude, Dead zone and Data Restore.
Ø LCD display: No.
Ø Data backup and restore.
