D-Series: D077

DIN Panel mount - Level monitor

with linearization and one high / low alarm output

The D077 is a versatile, panel mount level monitor with linearization and continuous level monitoring feature. In addition to the average Span, eight linearization points can be entered to compensate for the tankshape. The unit will interpolate between these points to increase the accuracy. This linearization affects all displayed information as well as the alarm output. With the level monitoring feature, one low level and one high level alarm value can be set.

Advantages
  • Unique, robust IP66, IP67 (NEMA Type4X) panel mount front enclosure made of die cast aluminum, allowing even big jets of water and total immersion.
  • Programming can be done by your own crew with the exact same, plain and sensible menu-driven structure like the F-Series, saving cost and irritation. Know one, know them all!
Application overview D077

Features

  • Displays level, height and percentage filled.
  • Eight point linearization of the tank shape - with interpolation.
  • Two alarm values can be entered: low and high level alarm.
  • Level: six large 17mm (0.67) digits.
  • Selectable on-screen engineering units; volumetric or mass.
  • Auto backup of all settings.
  • Ambient temperature: -40°C to +80°C (-40°F to 176°F).
  • Red flashing LED backlight in case of a level alarm.
  • Aluminum DIN front panel of 144 x 72mm (5.67" x 2.83") according DIN 43700 / IEC 61554.

Applications

  • The D-Series is a DIN-sized display and the better alternative for your existing, not waterproof, front panel mount indicators in extreme weather outdoor applications or e.g. in food industries where working environments are often cleaned with powerful water jets.
  • The D077 fits in level measurement applications where continuous level monitoring and linearization of the tankshape is important. Alternative basic models D070, D073, D074 or the F-Series level indicators.
