LT-635 Self-Wiping & Submersible Suspended Solids Sensor

The LT-635 is a submersible, waterproof, self-cleaning sensor that that determines the concentration of suspended solids by measuring the attenuation of an infrared light source through the sample media. The sensor automatically compensates for disturbances caused by flow fluctuation and color of the water containing high levels of suspended solids. The instrument is virtually maintenance-free and the self-cleaning capability of the sensor prevents deviations caused by air bubbles, sessile bacteria (slime) and sludge particulate resulting in highly accurate suspended solids measurement which can directly reduce operation costs while improving efficiency and environmental compliance.

The LT-635 can be powered by a 24 VDC/6W power supply and offers fully integrated 4-20mA 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 with-out calibration. Additionally, the LT-635 can be wirelessly accessed via the optional MA-CRBluetooth adapter accessory for local display, diagnostics, cleaning and calibration when using the uPyxis APP for mobile or desktop devices. The LT-635 is ideal for suspended solids measurement in activated sludge wastewater operations including aerobic and anaerobic basins and digestors, as well as clarifier/thickener sludge bed level detection.
