CS410 Shaft Encoder
1. General
Shaft encoders monitor fluctuations in water level and the position of water
control gates by converting shaft rotation to electronic signals which are then
measured by the datalogger.
The CS410 generates two pulse strings—one indicating clockwise and the
other counter-clockwise rotation.

4. Installation
Shaft encoders are typically mounted in a stilling well for protection and to
dampen waves. Attach the pulley to the CS410. If you have our pulley, part #
10799, it is secured with a 9/64” hex wrench. Mount the encoder in the stilling
well allowing for the pulley and tape to be unobstructed. Attach the end hooks
to the tape, followed by the float and counter weight. Then drape the tape over
the pulley.
