Catalogue excerpts

The FPA 4000/4100 is an online dual filter photometer capable of measuring the concentration of many analytes in process liquid or gas streams. The FPA 4000/4100 uses well established spectrophotometric techniques to perform the measurement. In general, energy from a source lamp is transmitted to a measurement cell via a multi-stranded fiber optics bundle. The sample continuously flows through the cell, where the analyte of interest will absorb energy from the light source. The energy that passes through the cell is then transmitted to a set of photodetectors via a bifurcated fiber optics bundle. The amount of energy absorbed by the sample is proportional to the concentration of the analyte in accordance with Beer’s Law. The FPA uses a single beam, dual wavelength design. The energy that passes through the measurement cell is split so that it is directed to two photodetectors, one for reference and one for measure. Each photodetector is equipped with a bandpass filter such that only a single wavelength is measured. The measure wavelength is selected in a region of the spectrum where the analyte of interest is known to absorb strongly. The reference wavelength is selected in a region of the spectrum where the analyte of interest does not absorb. The dual wavelength design compensates the measurement for turbidity of the sample, optical window coating and loss of light intensity over time. Performance Range Low ppm to % levels depending upon measurement Two isolated 4-20 mA inputs to permit the FPA units to be a communication hub for other devices which do not have that capacity. Intrinsically safe keypad with 20 keys for easy menu navigation. Instrument Specifications Response Time T90 30 seconds Streams One (1) stream (standard), with up to 8 streams (optional). Auto / Manual Mode AUTO mode: analyser runs in predefined sequence. MANUAL mode: user may select any stream to run.
