Inline Dissolved Oxygen Sensor Designed for Breweries

InPro6970i for brewing

Oxygen in beer bottles or cans is bad. It affects the flavor and shortens shelf life, so breweries do their best to prevent oxygen getting into beer  at the filling line.  The Mettler Toledo Process Analytics InPro6970i is an inline dissolved oxygen sensor designed specifically for the needs of the brewery industry. It can measure oxygen in beer at levels of only a few parts per billion.

The sensor is inserted in the pipe at the start of the filling line, and provides real-time measurements on the oxygen content of the beer.  If the oxygen level is too high, the flow of beer is stopped to prevent the out of specification product continuing down the line.

Unlike most dissolved oxygen sensors available, the InPro6970i uses a clever optical technique for measuring oxygen. At the tip of the sensor there's a layer of molecules that absorb and emit light. These molecules are sensitive to oxygen which alters how the molecules behave. The greater the quantity of oxygen, the greater the changes in their behavior. The sensor very accurately measures these changes and sends the signal to the transmitter.  This technique is extremely fast and accurate at measuring changes in beer oxygen level, which is why it is favored by breweries. But that is not the only requirement breweries demand.  Sensors must be rugged, easy to use, and simple to maintain.The InPro6970i scores highly in all these areas. The sensor's stainless steel body is extremely robust, the unit is easily and quickly installed, and the only maintenance required is the periodic exchange of the oxygen sensitive element, the OptoCap. Intelligent Sensor Management, or ISM, is a feature of the InPro6970i that offers significant benefits to breweries. The sensor can be calibrated in a convenient location such as a lab. Upon connection to the transmitter, the system is ready to measure in only a few seconds, so measurement point down time is very short. The dynamic lifetime indicator uses sophisticated algorithms to calculate the remaining life of the sensor, breweries therefore have confidence that the sensor won't fail unexpectedly.
