Water plays an essential role in many processes in today's modern world. This makes it all the more important that this valuable resource is not only used sparingly, but also kept clean. Permanent monitoring using modern measurement technology ensures cleaning performance.
With the NIR turbidity sensor EXpure 191, the company EXNER from Ettlingen is bringing a measuring device onto the market that allows the detection of the slightest levels of contamination in water. It impresses with its high accuracy and reproducibility when recording measured values.
As with all sensors from EXNER, the EXpure 191 also has high demands on quality and user-friendliness. A robust plastic flow cell and stainless steel measuring optics allow for reliable measurement. The optical unit itself is protected from process influences by resistant sapphire windows. The transmitter integrated in the device can either be used to output an analogue 4…20mA signal or digital communication can take place via Modbus RS485.
Another special feature of the EXpure 191 is the long-lasting LED light source, which significantly simplifies maintenance. At the same time, the user does not need to perform any complicated calibration of the sensor. Appropriate solid references are available to easily check the measured values.
This new type of turbidity sensor can be used in drinking water treatment, industrial water control, wastewater treatment or swimming pools.
