3.1 Application
The EZ 1000 is a signal converter for different types of eddy current sensors. The converter
is designed for the connection of eddy current sensors of the EZ 10xx series and a selection
from third party sensors:
• EZ 105x and EZ 108x
• Bently Nevada 3300 XL 8 mm Proximity Probes 33010x
The sensor adapter EZ1900-003-ADAP-2 is required for the connection of 33010x
probes.
The EZ 1000, in combination with eddy current sensors listed above, can be used for static
and dynamic distance measurements at a variety of different rotating machinery. This
means that slow axial displacements and fast radial vibrations of rotating machines can be
measured. By using pulse wheels or key marks stuck on the shaft, the speed of the
machine can be measured and key pulses generated.
The EZ 1000 is integrated into Machine Studio which allows an easy on-site calibration of
the converter to the sensor. Machine Studio also provides the opportunity of detuning the
converter if sensors are fitted closely together or to extend the standard measuring range
of several sensors.
Supply circuits for the eddy current sensor and the measuring electronic are contained in
the converter. The nominal supply voltage for the converter is -24 V DC, the nominal range
of the output signal, proportional to the nominal measuring range of the sensor, is
-2 to -18 V.
3.2 Design
The EZ 1000 is designed for DIN rail mounting within a field housing or cabinet. The
connection of converter supply and sensor signal is made by screw terminals. The
converter is equipped with a LEMO connector for connection of an eddy current sensor.
The USB 2.0 Micro-B socket is the interface for the configuration.

connections and operating elements.
