Sludge Blanket TSS Sensor

Sludge Blanket TSS Sensor

  • Measures Suspended Solids, Turbidity and Sludge Blanket
  • Connects to every type of recorder, transmitter, systemof remote processing or automaton endowed with anentrance Modbus RS485
  • Optical sensor based on absorptiometry

Range of measure:

  • SS: 0-50 g/L
  • Sludge Blanket 0-100 %
  • Turbidity 0-4000 FAU

Optical technology

Optical technologyThe principle of measurement is based on the mitigation ofthe Infra-Red signal in 870 nm through an optical path of5mm. The sensor delivers measures in Suspended Solid (g/l),Turbidity (FAU) and Sludge Blanket detection in % oftransmission IR. For better precision, the optics of the sensorare regulated in temperature.

  • For Suspended Solid, the sensor is directly calibrated onthe material to be measured (sample of sludge).
  • In Turbidimeter version the sensor delivers measures ona range 0-4000 FAU (Formazine Attenuation Unit) and iscalibrated with solutions of Formazine.
  • Temperature: measures and regulation of optics via CTN.

Digital communication / Integrated transmitter

The sensor PONSEL connects to every type of recorder,transmitter, system of remote processing or automatonendowed with an entrance Modbus RS485. Thanks to theindexation of the sensor, more than 200 sensors can beconnected on a recorder.

Resisting the disturbances: pre-development integrated intothe sensor and the digital treatment of the signals. All thedata concerning the calibration, the history and the usersare directly recorded in the digital sensor MES5.


A handle in DELRIN material assures the mechanical dress of thesensor and the sealing seals of the cable. Compact, tough andlight, the sensor allows use in portable version or fixed post.


  • Urban Wastewater treatment (Inlet/sewage water(SS, Turbidity), Aeration Basin (SS), Outlet (Turbidity)
  • Treatment of industrial effluents (Aeration Basin (SS))Clarifier (Sludge Blanket), Outlet (Turbidity)
  • Sludge treatment (Centrifugation)
  • Dredging site (Turbidity)
