New PSS spectrometers and accessories for in-field operation have been announced by Polytec. The new PSS 1721 and PSS 2121 spectrometers come in a 19″ half rack and have been designed for mobile vehicle applications.

Fully-automatic measurement procedures, such as on grain harvesters, are made possible by 12 V and 24 V power supplies and interfaces to connect the sensor head. The PSS-H-03 Conveyer Belt Sensor has been designed for continuous goods and non-contact measurements from distances from 150 mm to 500 mm. In contrast, the PSS-F-B01 Contact Sensor is suitable for contact measurements on powders, fluids and bulk material. The housing is made from stainless steel with a sapphire window, enabling measurements in highly demanding environments. In addition, both sensors meet the IP-64 industrial protection standard. A fully- automated system matching feature allows the transfer of calibration records from one system to another. The PSS-S-POP Process Software supports automated measurements and the visualisation of spectral results in both laboratory and production environments. A target value prediction is possible through use of modelling routines by SensoLogic and Unscrambler. Communication with process controllers is accomplished by Beckhoff TwinCAT I/O.
