Title (EN) PROBE FOR MEASURING TURBIDITY, HIGH TURBIDITY AND/OR SUSPENDED SOLIDS AT LOW CONSUMPTION
(FR) SONDE DE MESURE DE TURBIDITÉ, DE TURBIDITÉ ÉLEVÉE ET/OU DE MATIÈRES SOLIDES EN SUSPENSION À FAIBLE CONSOMMATION
Abstract:
(EN) A probe for measuring turbidity, high turbidity and/or suspended solids at low consumption, comprising: a power source; connected to a current limiter that supplies at least one capacitor connected to ground; said current limiter limits the current at its output to a maximum current of 1 mA; said at least one capacitor is connected to a controlled switch, which is in turn connected to an electronic circuit for measuring turbidity and suspended solids; a microprocessor which periodically opens said switch for a first predetermined time to recharge said at least one capacitor, and which periodically closes said switch for a second predetermined time to perform said measurement of turbidity and suspended solids; said electronic circuit for measuring the turbidity and/or suspended solids comprises a light emitter, a first receiver of the infrared light reflected by the suspended particles, and a second control receiver of the infrared light reflected.
(FR) La présente invention concerne une sonde de mesure de turbidité, de turbidité élevée et/ou de matières solides en suspension à faible consommation, comprenant : une source d'alimentation, connectée à un limiteur de courant, qui alimente en énergie au moins un condensateur connecté à la masse ; ledit limiteur de courant limite le courant au niveau de sa sortie à un courant maximal de 1 mA ; ledit condensateur est connecté à un commutateur commandé, qui est à son tour connecté à un circuit électronique permettant de mesurer la turbidité et les matières solides en suspension ; un microprocesseur qui ouvre périodiquement ledit commutateur pendant une première durée prédéfinie afin de recharger ledit condensateur, et qui ferme périodiquement ledit commutateur pendant une seconde durée prédéfinie afin d'effectuer ladite mesure de turbidité et de matières solides en suspension ; ledit circuit électronique permettant de mesurer la turbidité et/ou les matières solides en suspension comprend un émetteur de lumière, un premier récepteur de la lumière infrarouge réfléchie par les particules en suspension, et un second récepteur de commande de la lumière infrarouge réfléchie.
