BENTLY NEVADA SENSOR CABLE - 146055-05-02-05

Cable Sensor

The 3300 Ceramic Capped Probe is a state-of-the-art
solution for monitoring machinery in aggressive chemical or
high-pressure environments. The alumina cap and 304
stainless steel probe case provide robust protection and
increased life for applications in anhydrous ammonia or
other extreme pH environments. The ceramic capped probe
is compatible with the 3300 Proximitor Sensor and extension
cable.
Our Bently Nevada ceramic-capped probes are rated to 34
Bar (500 psi) pressure. Modifications are available for
applications involving higher pressures.
The 146054, 146055, and 164517 probes were developed for
applications that expose only the front of the probe case
assembly to corrosive gases and liquids. These ceramic
probe assemblies prevent corrosive gases and liquids from
entering the front end of the probe case. We leak test the
front-end ceramic to metal interface with helium to ensure a
hermetic seal. These probes do not have a rear fitting or
stainless steel tube, so that the rear of the probes are not
sealed. You must not expose the rear of these probes to
destructive environments such as water, NH3, NH4OH,
hydrogen sulfide, etc.
The 146056 ceramic probe assembly has the rear fitting and
stainless steel tubing to prevent corrosive gases and liquids
from entering both the front and rear of the probe case. We
leak test the front-end ceramic to metal interface with helium
to ensure a hermetic seal. The fitting at the rear end of the
probe is unsealed when it leaves the factory. You can
disconnect the tubing and the fittings from the probe case
and slide them out of the way while gapping and installing
the probe. Once you have secured and correctly gapped the
probe, you should tighten the fittings to completely seal the
rear of the probe.
