SIGNAL CONDITIONER &
CONVERTERS
PA1001A Series
INTRODUCTION:
with either magnetic or RF type pickup coils and allow convenient interfacing with process
measuring devices and digital electronics.
When used with Magnetic type pickups they accept low level signals and produces a pulse
output, while providing rejection of unwanted noise and false signals.
A RF type pickup reduces the pickup drag associated with conventional magnetic pickups,
resulting in a significant increase in the usable range. The PA1001A series excite a RF type
pickup with a 20KHz signal. Motion of ferrous material is sensed and the motion modulates
the coil field and subsequent conditioning provides a pulse output signal.
The output signal of the PA1001A series have a square pulse wave form, each pulse
representative of an actuator (rotor blade, gear tooth, turbine blade, etc.) passing by the
sensing area of the pickup.
Four output signal options are available:
i.
TTL/CMOS compatible
ii.
Open collector
iii.
0 to 10VDC square wave and
iv.
A square wave that is tied to the input power
.
The unit is powered by a user supplied 8 to 30 VDC filtered power supply. An on-board
regulator provides the required regulation and noise rejection.
Optional features include factory installed pulse scaling and field installable plug in modules
for Analog output. Pulse scaling provides the user with scaling options of
÷
2,
÷
4,
÷
8,
÷
16,
÷
32,
÷
64, or
÷
128, which is useful when a remote device has a maximum count speed that
is less than the pulse-generating device. Analog output provides a current and voltage
outputs proportional to RPM, flow rate etc.
