The FCX2000 offers
a simple and quick means of measuring and simulating frequencies, pulses,
numbers of revolutions, digital process signals and levels. The operator
guidance with the help of a 4- Iine LCD-display and membrane keyboard allows
simple and easy to use adjustment of all operator functions.
lt is possible to predetermine and measure NAMUR-
signals according to DIN 19234 as well as static logic levels in hazardous
locations, ranging from 0.01 Hz to 10 kHz with duty factors from 1 to 99 %.
Accurate numbers of revolutions can either be measured by NAMUR initiators
or by an optional external probe. For measuring revolutions on rotating
machinery with the probe a suitable reflection mark needs to be attached. A
visible beam of red light from the probe is then trained on this reflective
mark.
An important function for flow-metering is the
FCX2000 in the mode "pulse pre-determining" or "pulse measuring". Here pulse
length and pulse pause will be predetermined first, before a fixed
programmed number of pulses is released. The display in this mode shows,
what percentage of the programmed pulses have been sent. Whether a two
conductor NAMUR-initiator works properly or is malfunctioning can be checked
by another function.
The intrinsically safe FCX2000 is supplied
with standard rechargeable batteries. These are easily removed, but any
recharging must be done outside the hazardous area. An integral battery
level indicator shows when the batteries are becoming exhausted, so that
enough reserve operating time is ensured.
The lightweight metal housings designed to
ensure that the electronic parts of the FCX2000 are well protected so that
the equipment can be used safely and with confidence under the harshest of
industrial conditions. |
