Introduction
Product description
The signal conditioning instrument VEGAMET
407 Z is used for manifold applications for
continuous level measurement.
VEGAMET 407 Z is integrated in a series 400
plastic housing.
A sensor (pressure transmitter or capacitive mea-
suring electrode) can be connected via a two-core
line to the signal conditioning instrument. This line
is responsible for the power supply from the signal
conditioning instrument to the sensor. The measur-
ing currents are transmitted analog from the sensor
to the signal conditioning instrument and evaluated.
The signal conditioning instrument can be
calibrated and adapted to the measurement by the
user via parameter adjustment.
These adjustments are made without additional
facilities and tools via a 5-button keyboard
integrated on the front panel.
