2.5 Detector Personality Modules
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.

1. Back up and shut down the unit using the
2. Open the electronics enclosure door.
3. Disconnect the detector signal cable from the mezzanine module.
– FID and FPD mezzanine modules use SMA coaxial cables. Unscrew the nut to unplug
– Analog input mezzanine modules use small terminal block connectors that can be
4. Disconnect the fIlament detector cable if present.
5. Disconnect the RTD temperature input cables (top rear of unit, if present).
6. If present, take out screws holding the IS ground cables (typically only installed on modular
oven models).
7. Remove the nut on the bottom-front of DPM bracket.
