Product Description

Endress+Hauser Suspended solids Turbimax CUS51D Memosens sensor

This sensor utilizes multiple advanced measuring principles. The optics integrated in the sensor head enable measurement according to the 90 ° scattered light, 135 ° back - scattered light, and four - beam pulsed - light methods. These principles work in harmony to accurately detect the presence and concentration of suspended solids and turbidity in the liquid media. The four - beam alternating light technology, for example, enhances the sensor's ability to provide reliable readings even in complex media with varying particle sizes and distributions.

Benefits:

Turbimax CUS51D is a smart sensor that allows unattended operation in a wide range of process conditions. Its unique design is extremely robust and it is also low-maintenance thanks to its self-cleaning functionality. Choose from different integrated analytical models to adapt the sensor to your specific application. With Memosens digital technology, the CUS51D combines maximum process and data integrity with simple operation. It resists corrosion and moisture and enables lab calibration.

Turbimax CUS51D measures suspended solids and turbidity in:

1.Wastewater treatment plants:
- Solids content measurement in aeration, recirculation and sludge treatment
- Flocculent dosing
- Turbidity measurement in the outlet
2.Drinking and process water:
- Solids content measurement in sludge treatment
- Flocculent dosing
3.Utilities of all industries:
- Solids content measurement in aeration, recirculation and sludge treatment
- Flocculent dosing

2.Optimum adaption to all measuring tasks:
Sensor fits all measuring ranges thanks to numerous integrated analytical models.
3.Fast and easy commissioning: Sensor comes precalibrated and preconfigured ex factory.
4.Enables unattended plant operation: Intelligent design enables sophisticated self-cleaning capabilities and minimizes maintenance.
5.Perfect process adaption: Fast sensor positioning with holder and assembly system Flexdip CYA112 and CYH112.

One Sensor for All Applications:

Enables Unattended Plant Operation: 

Memosens Digital Technology: 

The 'one for all' principle of the Turbimax CUS51D optimizes stockholding. Instead of having multiple sensors for different applications or measuring ranges, a single CUS51D can be used. This not only reduces inventory costs but also speeds up project handling as there is no need to select and configure different sensors for various tasks. It also simplifies life cycle management as maintenance and calibration procedures are standardized for one type of sensor.

The intelligent design of the Turbimax CUS51D enables sophisticated self - cleaning capabilities. This is a crucial feature as it minimizes maintenance requirements. In applications where the liquid media may contain particles that can foul the sensor, the self - cleaning function ensures that the sensor remains operational and accurate over long periods. As a result, plants can operate unattended for longer intervals, reducing labor costs and improving overall process reliability.

The CUS51D incorporates Memosens digital technology, which combines maximum process and data integrity with simple operation. This technology resists corrosion and moisture, ensuring the long - term reliability of the sensor. Additionally, it enables lab calibration, which can be more accurate and convenient in some cases. All calibration and sensor - specific data are stored in the sensor, making it easy to manage and transfer between different measuring points or during maintenance.
