Bently Nevada 330195-02-12-10-CN 3300 XL 8 mm Extended Temperature Range Proximity Probe
The 330195-02-12-10-CN serves as an extended temperature range proximity probe. We distribute Brand New, Original Stock units with Global Shipping options.
Description
Configured for non-contacting vibration and displacement monitoring in high-temperature machinery zones, the Bently Nevada 330195-02-12-10-CN (330195 Proximity Probe) provides direct physical/electrical execution. Consequently, the sensor monitors dynamic parameters of rotating shafts without physical contact, transmitting raw data directly to 3500 series machinery protection racks.

Gap Voltage Validation and Eddy-Current Probe Scaling
Field technicians execute gap voltage validation to position the reverse-mount probe tip within the linear measurement zone. Specifically, proper calibration yields a -10 VDC target voltage when the target face rests at the exact midpoint of the 2.0 mm linear range. Furthermore, accurate eddy-current probe scaling requires matching with the standard AISI 4140 steel target chemistry. Therefore, this alignment guarantees precise rotor dynamics evaluation while specialized triaxial construction reduces external electromagnetic signal cross-talk.
Frequently Asked Questions
Q: What are the thermal operational limits of the ETR 330195 probe compared to standard 3300 XL probes?
A: The Extended Temperature Range probe tip operates continuously up to +218 deg C, whereas standard modules are capped at +177 deg C. This extended range protects the sensor head against degradation in gas turbine or steam environments.
Q: Can this reverse-mount probe be installed directly into a standard threaded machine casing hole?
A: No, reverse-mount probes require installation from the inside of the machine housing or through specialized reverse-mount housings. Technicians pull the cable through the mounting bore rather than threading the entire sensor head from the outside.
Field Installation Guidelines
First, verify the internal casing area is clean and clear of metallic debris. Next, insert the 1.0 m cable from the inside of the machine shell through the mounting bore. Additionally, thread the 3/8-24 UNF body into position until achieving the calculated clearance gap. Finally, execute a full 5-thread engagement to lock the probe casing, and connect the miniature coaxial ClickLoc connector to the extension cable path.
