Source measure units
Keithley, locally represented by Comtest, has on offer a compre-
hensive range of voltage, current, and power units available. Re-
cent innovations include the embedded TSP Test Script Processor,
industry-first graphical touchscreen interface, and other performance
enhancements. More than 20 models and systems have been
designed for demanding applications in research labs, on the engi-
neer’s bench, and in high speed ATE systems. Instruments with dc
and pulsed output levels from 10W to 2 000W are available. Some
more popular options:
• 2400 Graphical Series SourceMeter 1 channel; 20 – 1 000 W
• Optical SourceMeter 1 channel; <50 W
• 2600B SourceMeter – 1 or 2 channels; 30 W dc / 200 W Pulse
• 2650High Power SourceMeter; 1 channel; 200WDC / 2 000WPulse

Compact design
plastic flowmeter
KOBOLD, represented locally by Instrotech, has
on offer to industry their Model VKP flowmeter
that works on the Variable Area principle, still
one of the most-used measurement principles
in flow engineering. Instead of the conical meas-
uring pipe generally used, a conical mandril is
placed inside a housing made out of robust,
impact resistant polysulfone, on which there is
a float with a sharp-edged orifice. The incoming
medium flows through the float’s orifice and lifts
it up against the power of a stainless steel spring
onto the flow depending height. The actual flow
rate can directly be read off a scale affixed to the
outside of the housing. With the combination of
spring and conical mandril this series of meters
is far more compact than other commonly used
devices with a conical measuring pipe. They are
therefore ideal for measuring flow rates in ma-
chines and aggregates.
