bitumen truck manufacturing company uses a specially
programmed UNIMETER as a manual 4-20mA Pot. The 4-20mA
output of the UNIMETER is connected directly to a coil
that drives a Hydraulic pump. Hence by varying the current
through the coil using the UNIMETER's output, the operator
can manually control the pump speed using the membrane
keys on the UNIMETER's front panel.
Other potential UNIMETER applications for specialist
vehicles like this include; tank volume measurements,
temperature, pressure, distance and speed monitoring plus
Benefit: The operator can get a numerical
representation directly from the UNIMETER display that
represents the coil current and hence represents the pump
speed. Therefore the Bitumen truck operator can accurately
change the pump speed and get a numerical representation
of its speed.
The UNIMETER's versatility is another major benefit.
Since one meter can do all, only one meter has to be
learnt and this takes out the confusion of having to
remember how to operate and program a number of different
meters, all with different functions and controls.
