Introducing the Pyxis LT-635 Sensor
The LT-635 is a submersible, waterproof, self-cleaning sensor that determines the concentration of
suspended solids by measuring the attenuation of an infrared light source through the sample media.
The instrument is virtually maintenance-free
,
and the self-cleaning capability of the sensor prevents
deviations caused by air bubbles and sludge particulate. The LT-635 can be 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
<0.1g/L for up to 1-year without calibration. Additionally, the LT-635 can be wirelessly accessed via the
MA-CR Bluetooth adapter for local display, diagnostics, cleaning, and calibration when using the uPyxis
APP for mobile or desktop devices. The LT-635 is ideal for use in wastewater applications including
clarifier/thickener sludge bed depth detection and activated aerobic or anoxic suspended solids
detection.
