Output signal
Signal output digital VBUS output signal in two-wire technology
(VEGA-Bus).
the digital output signal (meas. signal) is
modulated to the power supply and further
processed in the signal conditioning instrument
or in the processing system.
Integration time (adjustable)
- in the sensor 0 … 999 seconds
- in the signal conditioning instrument 0 … 600 seconds
Load resistance of the signal cable max. 15 Ohm per
wire and max. 1000 m cable length
(with 15 sensors on one two-wire cable
max. 10 Ohm per wire)
