EXspect 271 is a highly accurate compact NIR turbidity sensor for monitoring production processes in the food industry, e.g. in dairies, as well as in many areas of process applications with medium and high turbidity. The robust and compact design in a stainless steel housing and the wear-free sapphire lens make the EXspect 271 a reliable backscatter sensor with integrated transmitter. The turbidity value can be shown directly on the display in % or in a freely definable customer-specific unit and output via the standard 4...20 mA interface. Two alarm limits can be programmed.
