Abstract

This invention relates to multipair tube light variation self compensation turbidity on-line detection alarming device and its test method including a case, a panel, host plate, display plate, turbidity sensor with turbidity transmitting interface plate connected with each other in which, the display plate and the host plate are fixed in the case in connection, the trubidity transmitting interface plate is in the sensor connecting with the host plate. The said method is to set up a test zone with reference turbidity module as the core and evaluate turbidity with linear interpolation in every zone.

Description

(1) Technical field [0001] The invention relates to the technical field of process measurement, in particular to online turbidity detection technology and equipment technology, in particular to a multi-pair tube dimming self-compensating turbidity online detection and alarm device and a detection method thereof. (2) Background technology [0002] The goal of the clarification process in water plants and the food industry is to remove impurities in the solution. The amount of impurities in the solution can be expressed by turbidity. Therefore, the online measurement of turbidity is very important. Only when the turbidity measurement is accurate can effective self-control be implemented. , If the turbidity index is too high, it will seriously affect the health of the public. Most of the existing turbidity on-line detection devices are imported equipment with complex structure and high cost; while domestically produced equipment is very small, most of them have no recording, al...
