BetaCAP30 is a gas divider that uses 30 capillaries, to operate 31 dilution ratios (between 0 and 100% of the concentration to be diluted). The choice of 30 capillaries is not aimed at carrying out tests on 30 steps, but to increase the diluter application flexibility reducing the number of required cylinder concentrations. With BetaCAP30 it is possible to perform linearity tests on 5 steps (0, 20%, 40%, 60%, 80%, 100% of the measurement range) using cylinders that contain up to 6 times the analyzer’s span concentration.

BetaCAP30X100 is a gas divider in two stages with 100 + 30 equal capillaries, designed to operate 31 dilution ratios linearly scaled between 0 and 100%) and 30 more between 3.000: 1 and 100: 1. While the first range of dilutions gets the main application of the analyzers for emissions, the second is aimed to tests of analyzers air quality (immission).

BetaCAP60-3G is a 60-step diluter, capable of diluting 2 gases in a diluting gas, in any relationship between them. BetaCAP60-3G was created to satisfy the need of combining linearity tests with the possibility of performing interference tests. For this purpose, having two components (measuring and interfering) pure or contained in mixture in different cylinders, these can be diluted differently and independently. To clarify the operating conditions, it is convenient to define the three gases as diluted gas, interfering gas and diluting gas : each of the three gases, can vary virtually between 0 and 100% (60:60) of the applied concentration. In reality, the possible variations obviously depend on the presence of the other two gases, and in particular, on the condition “gas to be diluted + interfering gas + diluting gas = 100% (or 60:60).

BetaCAP60X100 a compact diluter with 3 inputs (two gases to be diluted in a diluting gas), pre-dilution just for an input and flow comparator for self-checking with relative deviations calculation. BetaCAP60X100 is built complying with the principles that inspire the entire Be.T.A. production : equal capillaries, electronic pressures control and manifold construction in highly corrosion-resistant materials. Very similar to the BetaCAP60-3G model, is distinguished only by the addition of a module pre-divider by 100, inserted in series at the TG1 gas inlet (measurand).
