Used for magnetostrictive level meter
Output: 4~20mA with HART (2-wire)
Resolution: 0.03 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: 360orotation LCD display. More than one variable displayed on the LCD with backlight for dark environment.
- Data backup and restore.
