CAUTION !
Probe (Capacitance Sensor) Model Configuration
Welded fittings cannot be adjusted. Ensure the dimensions are such that
when the probe fitting is fully engaged, the probe does not tighten
against the bottom of the container! Contact AMI Sales if you have any questions concerning
the dimensions or options. See dimensional drawing below.

Active Length
This is the measurement range of the probe. It
starts 0.375″ above the bottom tip of the probe,
and ends 1″ below the upper-most vent hole on
the probe.
Overall Length
This is defined as the total length of the probe,
measured from the bottom tip to the top of the
connector. Contact the factory to discuss
lengths exceeding the
Maximum Overall Lengths:
100″ for ⅜″-diameter, and

**For expanded possibilities or FM-Approved requirements,
consider the AMI Model 32E and additional line of Industrial Probes.
***Custom probes require an AMI-approved customer-signed drawing.
“Custom” applies to any probe not falling in the “S”, “HCap”, or “RSvc”
Option categories. Also probes having a fitting other than the basic
M175NPT with BNC, those deviating from the length limits, or special
probes for use in conductive media.
