Photometric device and photometric method for determining the gross calorific value of a test gas |
摘要 |
A photometric device and method for determining the gross calorific value of a test gas, especially natural gas having a radiation source that produces a measuring beam and a modulation unit to modulate the measuring beam. A test cell with test gas and a receiver for the beam are arranged successively in the path of the measuring beam. The measuring signals of the receiver are supplied to an evaluation unit that includes at least one signal amplifier for the amplification of the signals. The signal amplifier is provided with adjustment devices to adjust the signal amplifier according the spectral properties of the measuring beam. The gross calorific value of the gas is indicated by the sum of the amplified measuring signals produced in a computing machine. |
