Frequently Asked Questions (FAQ)

What is the typical application of the 330850-91-05 sensor?
It is designed for differential expansion (DE) measurements in medium to large steam turbines, tracking rotor and stator expansion difference.

Can it replace older 7200 series systems?
Yes. The 3300 XL 25 mm system is a full physical and electrical replacement for standard 7200 series DE transducers.

What is the linear range of the sensor?
The system provides a linear range of 12.7 mm (500 mils), starting at approximately 0.63 mm up to 13.33 mm.

Is the probe cable high-temperature resistant?
Yes. The FluidLoc cable supports continuous operation up to 200°C and intermittent exposure to 250°C.

Does the 9.0-meter length include both probe and extension cables?
Yes. The total system length includes the probe and extension cable, summing to 9.0 meters.

Is monitor reconfiguration needed when replacing an older system?
No. The sensor output matches the older system, so reconfiguration is not required. However, the entire system must be replaced.

Is the sensor resistant to EMI/RFI interference?
Yes. It offers robust EMI/RFI immunity, ensuring stable operation even in electrically noisy environments and complies with CE standards.

Does the product have explosion-proof certifications?
Yes. It holds multiple certifications including CSA, ATEX, and IECEx, suitable for use in Zone 0 and Zone 2 hazardous locations.
