CUS52D turbidity sensor

CUS52D is a digital sensor used for measuring turbidity and particulate matter concentration in drinking water and process water.

Measurement Principle

The measurement principle is that the sensor operates based on the 90 ° scattered light principle, complies with the ISO 7027 standard, and meets all the requirements of this standard. The ISO 7027 standard is a mandatory standard for turbidity measurement in the drinking water industry.

When there is a deviation, the transmitter will trigger an error alarm

Calibration

When conducting factory calibration, each CUS52D sensor uses a dedicated Calkit solid-state calibration module. Therefore, the Calkit solid-state calibration module is matched (paired) with specific sensors one by one.
Users can use CUY52 calibration container to quickly and reliably calibrate sensors. By creating reproducible basic operating conditions (such as containers with minimal backscattering, shields that block interfering light sources), it is easy to adapt to the current measurement point. There are two different types of calibration containers that can be used to fill calibration solutions (such as formalin)

Memosens Digital Sensors

Memosens digital sensors must be connected to Memosens digital transmitters for use. The analog sensor cannot transmit to the transmitter normally
Memosens digital sensors store calibration parameters, operating time, and other information through built-in electronic components. By connecting to a transmitter, the parameters can be automatically transmitted for measurement and calculation. It supports offline calibration, quick replacement, pre maintenance planning, and historical data archiving, thereby improving measurement quality and equipment availability.

Electrical Connection

There are two ways of electrical connection: 1. M12 plug connection, 2. Sensor cable directly connected to the input signal terminal of the transmitter

Working Parameters & Error

The working temperature is generally 20 ℃, and the maximum measurement error is: turbidity is 2% of the measured value or 0.01 FNU, and solid content is less than 5% of the measured value or 1% of the maximum range. The measurement error does not include the error of the standard solution itself. When measuring the solid content, try to make the medium distribution relatively uniform, otherwise it will cause fluctuations in the measurement value and increase the measurement error.

Installation Guidelines

Install instance
Sensors should be installed in locations with stable fluid conditions, preferably in pipelines where the medium flows vertically upwards, or in horizontal pipelines; It is strictly prohibited to install in locations where gas accumulation, bubbles, or deposition are likely to occur, and to avoid installing in pipelines where the medium flows vertically downwards. It is also prohibited to install fittings behind the pressure reducing pipe section to prevent degassing.  

Environmental Specifications

The ambient temperature range is between -20... 60 ℃, and the storage temperature is between -20... 70 ℃. The highest protection level can reach IP68, and the temperature range of stainless steel sensors is between -20... 85 ℃. If it is plastic, the highest temperature will be lower.
