EXspect 271
NIR backscattering sensor in compact design
The EXspect 271 is a highly accurate, compact NIR turbidity sensor for use in a variety of medium- and high-turbidity process applications in the food industry, such as in dairies. It’s a reliable back scattering sensor with an integrated transmitter thanks to its compact and durable structure in the stainless steel housing and non-wearing sapphire lens.
The turbidity value can be output via the standard interface 4…20 mA and displayed directly in the display in percent or a freely defined customer-specific unit. There are two alarm limits that can be set.
