MAGNETIC PICKUP

AMPLIFIER

M1945/0603

General Description

The FLSC-AMP-A Signal Conditioner will amplify low level signals from magnetic pick-up sensors, such as a
turbine meter or paddlewheel sensor, to an amplified high level square wave pulse output proportional in
amplitude to the power supply powering the module. This output will drive any OMEGA

flow ratemeter,

counter, controller or pulse input data acquisition board.

Unpacking

Remove the Packing List and verify that you have received all equipment. If you have any questions about the
shipment, please call the Customer Service Department.

When you receive the shipment, inspect the container and equipment for any signs of damage. Note any
evidence of rough handling in transit. Immediately report any damage to the shipping agent.

NOTE

The carrier will not honor any claims unless all shipping material is saved for their examination.
After examining and removing contents, save packing material in the event reshipment is necessary.

The following items are supplied in the box:

Hookup (Refer to Figure 1)

For electrical connections, the terminal strip will accommodate up to a 14 gauge wire. 18-20 gauge is
recommended.

Note: The signal lines from the magnetic pick-up should be shielded and kept less than ten feet and away from
relays, solenoids, or other sources of electrical noise. The signal shield should be connected to power/common.
The module output is recommended to make long distance runs.
