IR Optical Sensor
Simples, Robust and
Reliable! That the recipe PONSEL has been applying for 50 years.
The APW-VB allows, at
lower cost, the detection the height of the sludge fog decantation
basin or any medium presenting a vertical profile of turbidity.
The sensor use the
principle of optical absorption of the Infra-Red light. A
measurement of 100% correspond to a ultra-clear water (without any
suspended solid) and a measurement of 0% to a fully opaque sludge
(concentrated sludge). So it becomes very easy to located the
interface of sludge blanket.
