3300 XL Underwater Probes
Datasheet

Bently Nevada Machinery Condition Monitoring

175852 Rev. FDescription
3300 XL underwater probes are designed specifically for
applications involving constant exposure to liquids, such as
those in hydroelectric plants or sewage treatment facilities.
These designs also seal the probes against gases. All ourunderwater probes are rated to 500 psi (34 Bar) on theinterface between the tip and probe casing. Contact a sales
representative for applications that require higher pressure
ratings.
All of the underwater probes are compatible with standard
3300 XL Proximitor Sensors and extension cables. Note thatthese probes each belong to a different family (8mm, 11mm,or 25mm) and consequently require different ProximitorSensors and extension cables. Refer to the standard data
product sheets to obtain ordering information for the 8mm,11mm, and 25mm transducer systems.
The 100630, 148239, and 174985 probes were developed for
applications in which the entire probe is submerged orexposed to fluids. Tubing attached to the probe case protects
the probe cable, but the connector end of the probe is notsealed against liquids and must not be submerged. Inaddition, the probe case is made of 304 Stainless Steel and is
not suitable for salt-water applications. Contact a sales
representative if you have an application involving salt water.

1. The exposed plastic surface of the Probeswith 50 mm diameter, under certain
extreme circumstances, may generate
an ignition-capable level of electrostatic
charge. Therefore, this version of theequipment shall not be installed in alocation where the external conditionsare conducive to the build-up ofelectrostatic charge on the plastic
surface. In addition, the equipment shall
only be cleaned with a damp cloth. This isparticularly important if the equipment isinstalled in a Zone 0 location.
