Engineering Insight & Performance Summary

The 330302-000-011-50-90-00-05 represents a specialized high-temperature sensor engineered by Bently Nevada for extreme thermal environments. Part of the 3300 High Temperature Probe family, this unit utilizes a ceramic probe tip and AISI 316L stainless steel casing to withstand continuous operating temperatures up to +350°C (+662°F). Industrial instrumentation technicians rely on this model to monitor radial vibration and axial position on heavy turbomachinery where standard sensors fail due to heat degradation.

Frequently Asked Questions

Why does this model utilize a ceramic probe tip instead of polyphenylene sulfide?
Ceramic material maintains structural integrity and electrical stability under continuous exposure to extreme temperatures up to +350°C, whereas standard plastic tips degrade in high heat.

What is Global PLC Spare HUB's Insight on hardline cable handling during installation?
Global PLC Spare HUB recommends avoiding sharp bends on the 5.0-meter stainless steel hardline section, as severe kinks can damage the internal coaxial dielectric and alter signal propagation.

How does thermal expansion affect the linear scale factor of this probe?
Over operating temperatures from 22°C to +350°C, the incremental scale factor remains within ±30% of 3.94 V/mm, ensuring predictable signal scaling under hot conditions.

What precautions are necessary when setting the initial gap for high-temperature probes?
Account for thermal growth of the rotor during startup; setting the cold gap too tight can drive the probe out of its linear range as the shaft expands toward the sensor tip.

Can unarmored extension cables like option 00 be routed through open cable trays?
Unarmored cables should be run inside protective metallic conduit if installed in heavy industrial areas to prevent mechanical crushing or chemical damage to the outer jacket.
