The new EXspect 231 NIR absorption sensor from EXNER is not only compact and robust, but also can be used in a multitude of processes and, at the same time, is easy to use.
With the EXspect 231 absorption sensor, EXNER brings a measuring device to market which can be reliably used to determine turbidity in a multitude of processes. The new type is based on the tried and tested EXspect 230 and EXspect 250 sensors. The robust stainless steel housing of the sensor has a hygienic design and is executed in protection class IP69. The measurement itself is done in the near infrared range (NIR) with a wavelength of 850 nm, which allows colour-neutral measurement. The LED light source and the detector are protected by a durable sapphire window. Cleaning by means of CIP / SIP processes is possible. For the calibration and verification of sensors in the field NIST-traceable reference filters are available.
Thanks to its hygienic and simultaneously robust design, the EXspect 231 sensor can be used for a wide variety of applications not only in the food industry, but also in the processing industry, as well as in environmental technology. Applications like the monitoring and control of separators, the determination of yeast concentrations in breweries, concentration measurement in the headbox in paper production, and the monitoring of purification processes in dairies, for example, are belonging to the areas of application.
The sensor is available in a variety of configurations and can thus be optimally adapted to suit the customer’s requirements. The new EXspect 231 type replaces the previous sensor types 230 and 250 of the EXspect range.
