Mezzanine Modules
A mezzanine module conditions the signal from a non-conductivity detector. The mezzanine
plugs into the Base3 DPM in order to tailor the DPM for a specific measurement.
Three primary types of mezzanine are available to accommodate FID and FPD detectors, and
various detectors that produce a scaled analog output (AI) mezzanine. Some of the
mezzanines have a dual range function for maximum flexibility. See the table below for details
relating to the various mezzanine options.
The AI mezzanine can be used for reading a detector voltage signal from a specialized or third
party detector, such as the Valco PDD, where the device only supplies a scaled voltage output.
The AI signal will be treated like a normal detector signal, with a 50% balance range.
