Wally Box III, model CPH7600
Description
General information
With the model CPH7600, Wally Box III, WIKA oers a further
development of the well-known Wally Box I and Wally Box II.
The Wally Box III is a compact, portable pressure calibrator, which has been designed for mobile use as well as for
stationary workshop and laboratory testing. A special feature
of this test instrument is that it is tted with two independently-operating pressure systems.
One pneumatic system is designed to be supplied from an
external pressure supply, while the supply pressure of the
second system is generated by the integrated electrical
pressure generation. This enables the user to perform dierent measurement tasks or calibrations, regardless of external
pressure and power supplies.
Accuracy
The Wally Box III provides an accuracy of 0.025 % of reading
±0.01 % FS for the built-in pressure sensor. The temperature
compensation of the built-in sensor safeguards the accuracy
for applications in the eld. Readings can be displayed in one
of 13 standard units.
Features
With the Wally Box III, not only accurate pressure measurements are possible, but also exact current and voltage
measurements, as well as a DC 24 V supply for test items.
Pressure values and electrical measured values are simultaneously shown in the display.
The calibrator is integrated into a robust, as well as dust and
watertight transport case. Thus the mobile pressure calibrator
is particularly suited to use in harsh industrial environments.
A ow diagram on the front panel gives information on the
connection of the individual pneumatic components.
With the built-in NiMH rechargeable battery, a battery life of
50 hours or 125 pump cycles up to 20 bar is guaranteed. The
external universal power supply is designed for an operating
voltage of AC 100 ... 240 V.
