Because the sensor optics are in the process stream, the Model 951 suspended solids sensor does not require bypass systems. Our in-stream measurement eliminates slow response times inherent with turbidimeters requiring bypass plumbing. The Model 951 is extremely effective where filter monitoring is crucial, and efficiency or breakthrough must be detected quickly.
Wide Dynamic Range
Our suspended solids sensor can be scaled from as low as 0-2000 ppm to as high as 0-20% TSS. The 0-2000 ppm range gives low level readings with high resolution for use downstream of clarifiers or on raw water supply. Ranges above 2000 ppm can be used for measuring high concentration solids or detecting sludge levels in clarifiers.
Handles Harsh Process Conditions
The optical design of the sensor minimizes the effects of fluid color, flow, chemicals, temperature & pressure. Our instrument operates under a wide range of temperature and pressure conditions. Robust wetted parts are 316 stainless steel and glass for high resistance to process chemicals.
Our suspended solids sensor comes standard with an isolated 4-20mA output for connection to control/monitoring systems. Other outputs are available.
The Model 951 uses a light source with a 13-year life expectancy which provides long-term stability and very low maintenance. Although our suspended solids sensor is easily calibrated by the end user, calibration drift is minimal. Because sensor removal is simple, the optics can readily be cleaned as necessary.
