Application and design
3.1
Application
The AMS EZ 1000 Converter is a signal converter for different types of eddy current
sensors. The converter is designed for the connection of eddy current sensors of the AMS
EZ 1000 Sensor series, the listed types of the PR 642x series, and a selection of third party
sensors:
•
EZ105x-xx-xx-xxx, EZ108x-xx-xx-xxx, EZ116x-xx-xx-xxx,
•
PR 6424/0xx-xx0, PR 6425/010-1x0, and PR 6426/0x0-xx0
The sensor adapter EZ1900-003-ADAP-1 is required for the connection of these
sensors.
•
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 AMS EZ 1000 Converter, 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 AMS EZ 1000 Converter is integrated into AMS Machine Studio which allows an easy
on-site calibration of the converter to the sensor. AMS 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 AMS EZ 1000 Converter 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.
