Step 1:
Current measurement of up to 12 compressors
A special advantage is that up to 12
compressors can be measured at the
same time with 3 DS 300 mobile.
So compressed air stations which are often
far away from each other can be measured
separately and then
summarized synchronously in one evalua-
tion at the PC.
Step 2:
Analysis of the measured values at the PC
Compressor analysis
(current measurement)
The energy consumption of every
single compressor is measured by means
of a clamp-on ammeter. The produced
compressed air quantity is calculated
by the software on the basis of the
performance data of the compressor which
have to be entered.
The following parameters are calculated
additionally: Energy consumption in
(kWh), load-, idle-, stop time, compressor
load in %, number of loads/load removal
(load cycles).
System analysis (current
measurement and real
consumption measurement)
The system analysis has the same
function like the compressor analysis,
however, it additionally offers the
possibility to measure the actually
produced resp. used quantity of
compressed air by means of the
consumption sensor VA 400.
With the additional "real consumption
measurement" the leakages and
therefore the cost share of the
leakages in comparison to the total
costs in € can be determined.
Leakage calculation
The leakage calculation is done during the
production free time (shutdown, weekend,
holidays). The consumption sensor
VA 400 measures the supplied quantity of
air. During the down time the compressor
delivers compressed air in order to keep a
constant pressure. According to statistics
even if production is carried out day and
night there is at least one short period of
time during which all load is switched off.
By means of this data the software defines
a leakage rate and calculates the incurred
leakage costs in €.
