Sensor assembly for measuring turbidity

Abstract

The invention provides a sensor structure for measuring the turbidity, which comprises a transmitter and a receiver. The sensor characterized in that the transmitter is a light-emitting element 1 for dissipating ultraviolet and the receiver is a light-receiving element 2. The light-receiving element 2 is arranged to be at an opposite position with the light-emitting element 1 and the light-emitting element 1 is at a certain distance from the light-receiving element 2. The sensor is low in cost and small in the error of the measurement range, which can effectively perform the turbidity measurement. Meanwhile, the turbidity can also be measured during the movement of the sensor. Therefore, the sensor can be widely applied to the turbidity measurement for various fluids.

Description

technical field [0001] The invention relates to a sensor assembly, in particular to a sensor assembly for turbidity measurement. Background technique [0002] In general, the turbidity measurement sensor used to detect the turbidity of the fluid includes: a transmitter (Transmitter) that emits a measurement beam (usually using high frequency), and is used to receive the beam emitted by the transmitter. The receiver (Receiver) that comes out and passes through the stream of fluid. [0003] During measurement, the value of the measurement beam diverged by the transmitter is compared with the value of the beam absorbed by the receiver after passing through the fluid to be measured, so that the transmittance of the fluid, that is, the turbidity of the fluid, can be measured. However, this device uses a transmitter (transmitter) as a high-frequency diffuser and a receiver as a sound wave detector for absorption, and its high price is a problem. [0004] Not only that, when the ...

AI Technical Summary

Problems solved by technology

[0006] However, the emitter that generates the laser beam as described above is not only expensive in itself, but also requires the installation work of aligning the emitter and receiver precisely, making the measurement very troublesome

In addition, the existing sensors for turbidity measurement can be used fixedly in a fluid channel or a fluid storage space, but it is almost impossible to use them in a mobile manner along the fluid storage space or fluid channel

Therefore, the field where existing sensors for turbidity measurement can be used will also be narrowed, and the practical value of sensor products will be further reduced
