Calibration


without the requirement, and cost, of developing a bespoke solution.


In practice, customers will not need to buy Echo separately, because it is a built-in feature for Echo- compatible Vaisala measurement products. Simple to set up and run, Echo provides reliable, always-on access to data and alerts from all compatible devices, with remote firmware updates for all connected devices.


A major benefit of Echo is easy access to comprehensive reporting – both current and historic. Echo reports current conditions in real-time and enables notifications/alerts, and all data is encrypted in transit and rest, and secured with digital certificates.


CASE STUDY: SAUSAGE CASINGS A team of UK process engineers has developed a technique for manufacturing collagen sausage casings which protects product quality and trebles output. The process relies on precise monitoring of

temperature and humidity with Vaisala sensors, combined with multi-stage feedback control. The manufacture of collagen sausage skins from animal hide is a good example of sustainable production because it recycles a waste product into a valuable commodity that helps to improve the quality and consistency of sausages. However, all sausage casings are delicate and require precise conditions and careful handling during manufacture, storage and distribution, and throughout the subsequent sausage manufacturing process. Natural casings from the small intestine of meat animals tend to be variable in length, diameter and thickness, so they are not ideal for high-speed sausage manufacturing processes. In contrast, collagen casings offer reliable, consistent features, and are therefore ideal for fast, efficient processes. Also, collagen casings do not need to be stored in chilled conditions and have a longer shelf-life
