Although the M and the TF Series probes may be installed
directly in the process line, more often these probes are inserted
into a sample system. The sample system protects the probes and
enables the user to easily remove the probes for calibrating,
servicing and cleaning. Sample systems also control various
process and environmental conditions so that the moisture probe
or sample system operates within specifications.
The M and the TF Series probes, when operated with a
BASEEFA-approved PM880, are intrinsically safe and designed
to meet the requirements of IEC/CENELEC zone 0 areas.
The M and TF Series probes measure moisture content in a
standard range from -110°C to 20°C (-166°F to 68°F) dew/frost
point temperature and optionally from -110°C to 60°C (-166°F to
140°F). Both probes optionally measure temperature in a range of
-30°C to 70°C (-22°F to 158°F). The TF probe optionally
measures pressure from 30-300/50-500/100-1000/300-3000/500-
5000 PSIG.

The Moisture Image Series Probe measures moisture,
temperature (optional), and pressure (optional). The Moisture
Image Series Probe has its own electronics module that consists
of a built-in microcontroller with 16-bit resolution. See Figure 9-
4 below.
