One monitor handles all beer specifications
15 Jan 2000
Paar Scientific has introduced an in-line beer monitor that, with only a single density/sound transducer, can measure alcohol, extract and original extract.
The highly accurate, compact DSRn 427 sends density, sound velocity and temperature measurements to Paar's mPDS 2000 controller. Together they can determine the percentage alcohol, real and apparent extracts, original extract and degree of temperature for up to 31 different types of beer.
The controller has a large, easy-to-read display, adjustable upper and lower alarm limits, analogue outputs for connections to loop controllers, recorders or remote displays, and an RS232 interface. There is also an input for a CO2 signal, such as from Paar's Carbo 2000 analyser, which can be used for compensation purposes.
Combining density and sound velocity measurements in the one transducer, however, minimises influences from varying CO2 content. But for complete compensation, a CO2 monitor can be connected to the controller through one of the 4-20mA inputs.
