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.

Product model series
