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
counter, controller or pulse input data acquisition board.
Unpacking

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.
Mounting
The FLSC-AMP-A module may be mounted using the screw holes provided in the molded housing. Doublesided tape, Velcro, or glue may also be used to secure the module in place. The FLSC-AMP-A module can also
be snap track mounted using an adapter plate.
