EXspect 260 is a high precisely compact NIR immersion sensor monitoring turbidity or absorption of production processes in the food and pharmaceutical industry as well as in many ranges of process and chemical applications. The robust and compact structure in the stainless steel housing and the wear-free sapphire windows make the EXspect 240 a reliable absorption sensor with integrated transmitter. Two alarm limits can be programmed over the measuring range from 0… 100.0%. The sensor provides an analogue output of 4… 20mA. It is mounted onto the process by a thread PG13. The installation dimensions correspond to a standardised pH sensor. Thus this sensor can be used also in combination with fully automatic cleaning systems by our proven pH retractable holders of series Extract 8XX and the associated control unit EXmatic 460. A fully automatic cleaning of the measuring windows under process conditions makes that system suitable for the reliable employment also in most difficult applications. Thus this sensor is suitable in particular for concentration measurements, product separation, centrifuge and filter monitoring as well as waste water control.
