The LT-63X Series sensor platform (including the LT-631, LT-632 and LT-633) are submersible, waterproof, self-cleaning sensors utilize dual infrared detection technology to measure turbidity in the ranges of 0 to 4000 NTU. The sensor automatically compensates for disturbances caused by flow fluctuations, climate change, color change or changes in turbidity. The instrument design is virtually maintenance-free, and the self-cleaning capability of the sensor prevents deviations caused by air bubbles and suspended solids particulate. It is powered by a 24 VDC/6W power supply and offers fully integrated 4-20 mA and RS-485 Modbus output signals for connection to any controller, PLC or DCS network. When clean, the unique Pyxis sensor design offers a stability of <0.1NTU for up to 1-year without calibration. Additionally, this sensor platform can be accessed via the MA-CR Bluetooth/USB adapter for local display, diagnostics, auto-wiper programming, sensor cleaning and calibration when using the uPyxis APP for mobile or desktop devices. The LT-63X series sensor is ideal for use in raw water, surface water, storm water, process water and discharged water applications.
