Corona Process

Introduction

Perfectly coordinated components combined with new ZEISS ProcessAssist systems make Corona process one of the safest spectrometer systems. The quality parameters which are relevant for your process can be measured even more comfortably using the ZEISS ProcessAssist.

Corona process warns you if critical limit values are being exceeded and a reaction is required immediately. The automatic logging of the environmental conditions always ensures reliable measuring results regardless of the sample height, temperature, air humidity or vibrations. If necessary, it also controls internal referencing. To avoid down time, bulb functioning is also monitored automatically. If a bulb fails, the second full-power bulb is deployed immediately and the Corona process can continue its tasks uninterrupted.

Benefits

Every process is different and has its own very unique conditions – some of which may be extreme. However, for the new Corona process this is not a problem. The large spectral range which covers the visible and the near infrared range enables a broad spectrum of applications.

With its compact build, Corona process may be easily integrated into any technological process. The optics, spectrometer, electronics and referencing are all located in the same housing together with the measurement head, so that only one installation site is required. Since there is no need to use light guides, influencing and losses do not occur. Thanks to its stainless steel housing, Corona process not only looks good, it also meets all hygiene requirements. This measuring system boasts excellent long-term stability and does not require frequent external calibration. At a distance of 80 to 600 mm from the sample, it measures with the same accuracy all the time. This is unaffected by temperature fluctuations from – 10 to + 50 °C. Corona process is protected against shock and vibrations and delivers analysis data reliably in all process environments. The bulbs have a total service life of 20,000 hours – making them fit for continuous operation for two years. In addition, the new Corona process requires remarkably little maintenance.

Usages

For the highest demands: Corona process

The requirements in food production environments concerning quality and hygiene are extremely high. The careful use of resources and the avoidance of waste are important factors in terms of the environmental scorecard. To ensure profitable production, process inspections and optimization take on major importance. Corona process allows producers to put economic and environmental claims into practice – no matter in which field of the food industry they are operating.
