Specifications and Ordering Information Part Number 172932-01 Rev. A (05/07) Page 1 of 9 3300 XL Ceramic Capped Probe Description The 3300 XL 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 XL 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. Probes 146054,146055, & 164517 were developed for applications where only the front of the probe case assembly is exposed to corrosive gases and liquids. The ceramic probe assemblies without the rear fitting and stainless steel tubing (146054, 146055, and 164517) prevent corrosive gases and liquids from entering the front end of the probe case. The front-end ceramic to metal interface is helium leak tested to ensure a hermetic seal. The rear of the probes are NOT sealed and must NOT be exposed to destructive environments (e.g. water, NH3, NH4OH, Hydrogen Sulfide, etc.) The ceramic probe assembly with the rear fitting and stainless steel tubing (146056) prevents corrosive gases and liquids from entering the front and rear of the probe case. The front-end ceramic to metal interface is helium leak tested to ensure a hermetic seal. The fitting at the rear end of the probe leaves the factory unsealed. The tubing and the fittings can be disconnected from the probe case and slid out of the way while the probe is being electrically gapped and installed. Once the probe is secured and gapped correctly, the fittings should be tightened. This completely seals the rear of the probe.
