TURBIDITY SENSOR WITH LOW SIGNAL AMPLIFICATION
Abstract:
Controlled optical sensor device (10; 100) comprising an optical emitter (21) generating optical radiation (23), in particular in the visible or infrared field, and an optical receiver (22) to detect said optical radiation (23) upon interaction with a medium to be measured (24), a driving current (CTU; Ip) of said optical emitter (21) setting the intensity of said radiation (23) being controlled by driving means (50, 40). According to the invention, this device comprises a circuit (30) for conditioning the output signal supplied by the optical receiver (22) including an amplifier (31) to which said output signal (52) of the optical receiver (22) is supplied as input voltage (Vin) of the amplifier (31), said amplifier (31) including a feedback network (310) configured to determine a gain (G) of the amplifier (31) and to supply a reference voltage (Vref), said amplifier (31) being configured together with said feedback network (31) to supply an output signal (Vo) of the amplifier (31) which is a function of the difference between the reference voltage and the difference, multiplied by the gain (G), between said reference voltage (Vref) and said input voltage (Vin) of the amplifier (31).
