MODEL 50386SE-109 : SDI-12 Shaft Encoder with Display

General Description:

The Model 50386SE-109 SDI-12 Shaft Encoder with Display is a low-power shaft encoder designed for battery-powered field operation for the measurement of water level or floodgate position. A 6-digit LED display is provided on the top face for viewing data at the site location. Switches for setting and adjusting the stage (water) level, the SDI-12 address, and shaft rotation increment direction are located beneath a protective cover on top of the encoder. The encoder operates with standard float tape or bead chain pulleys and float hardware.
