330301-000-011-50-90-01-05 Bently Nevada 3300 XL High Temp Probe

Product Overview

• The 330301-000-011-50-90-01-05 is a specialized 3300 XL High Temperature Proximity Probe designed for extreme 350°C environments.
• It features a high-purity ceramic tip and 316L stainless steel case for superior thermal and chemical resistance.
• This 11mm probe system includes both a 5.0m hardline section and an armored extension cable for a 9.0m total length.
• It is the critical sensing component for "Hot End" gas turbine and steam turbine monitoring.
  

Global PLC Spare HUB's Insight

• Our team recommends the 330301 series when operating temperatures exceed 177°C.
• The ceramic tip construction prevents thermal deformation, ensuring the 100 mV/mil scale factor remains accurate.
• The 5.0m hardline allows the flexible cable connection to reside in a cooler environment, extending system life.
• This configuration is specifically suited for high-pressure exhaust frames and heavy-duty industrial pumps.

• Verify that the 30.5mm minimum target size is available on the shaft for accurate readings.

Industrial Expert FAQ

• Why does this model use a ceramic tip instead of standard PPS plastic? Ceramic maintains its shape and electrical properties at 350°C, whereas PPS would melt.
• What is the purpose of the 5.0m hardline section? It acts as a thermal bridge, keeping the flexible extension cable connectors away from the high-heat source.
• Can I use this probe with a standard 3300 XL Proximitor? Yes, provided the Proximitor is specifically calibrated for an 11mm probe and a 9-meter total length.
• Does the 12-month warranty cover exposure to 350°C? Yes, the unit is fully rated for continuous operation at 350°C under the warranty terms.
• Is the 316L SST case suitable for corrosive environments? 316L provides excellent resistance to the sulfur and chlorides often found in turbine exhaust gases.
