The 330851-02-000-030-10-00-05 is a high-performance, large-diameter proximity probe designed for the demanding environment of steam turbine differential expansion (DE) monitoring. As a key component of the 3300 XL 25 mm Transducer System, the 330851-02-000-030-10-00-05 features an M30x2 metric mounting thread, an unthreaded length of 0 mm, and an overall case length of 30 mm.
Engineered for extreme conditions, the 330851-02-000-030-10-00-05 offers exceptional thermal and environmental resilience. It is designed to operate continuously with maintained accuracy at temperatures up to 200 °C (392 °F) and can withstand intermittent exposures up to 250 °C (482 °F).
The 330851-02-000-030-10-00-05 provides a significant electrical output with a wide measurement range. It forms part of a system with a sensitivity of 0.787 V/mm (20 mV/mil) and an extensive linear range of 12.7 mm (500 mils). This large range makes the system incorporating the 330851-02-000-030-10-00-05 ideally suited for measuring the substantial differential growth between a turbine rotor and its stator in mid-size to large steam turbine generators.
As part of a versatile product family, the 330851-02-000-030-10-00-05 represents one specific configuration. The 3300 XL 25 mm probe platform is available in numerous case styles to physically replace all previous 25 mm and 35 mm transducer systems, including variants with 1¼-12 or 1½-12 UNF threads, M39x1.5 metric threads, and side or rear exit models.

FAQS
The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the primary application and measurement range of the 330851-02-000-030-10-00-05 probe?
The 330851-02-000-030-10-00-05 is specifically designed for measuring Differential Expansion (DE) on mid-size to large steam turbine generators. It is part of a system with a wide linear range of 12.7 mm (500 mils) and a sensitivity of 0.787 V/mm (20 mV/mil), making it capable of accurately tracking the significant relative growth between the turbine rotor and stator.
What high-temperature capabilities does the 330851-02-000-030-10-00-05 offer?
The 330851-02-000-030-10-00-05 is engineered for harsh turbine environments. It can continuously operate and maintain accuracy at temperatures up to 200 °C (392 °F). Furthermore, it is built to withstand intermittent exposure to even higher temperatures up to 250 °C (482 °F), ensuring reliability during transient conditions like turbine startups.
How does the 330851-02-000-030-10-00-05 facilitate an upgrade from legacy 7200 or 25 mm DE Integral systems?
The 330851-02-000-030-10-00-05 is part of a system designed as a direct physical and electrical replacement. Its associated Proximitor Sensor provides an output identical to the older 7200 and 25 mm DE Integral systems, allowing for an upgrade without requiring changes to the existing monitor configuration or scaling. However, the entire transducer system (probe, cable, proximitor) must be replaced with 3300 XL 25 mm components like the 330851-02-000-030-10-00-05.
What environmental protection and installation features are standard on the 330851-02-000-030-10-00-05?
The 330851-02-000-030-10-00-05 features robust protection: a standard FluidLoc cable and front and rear seals prevent moisture ingress. It includes high-temperature ClickLoc connectors with connector protectors and an installation tool to prevent contamination. For mounting, it comes with a locknut with pre-drilled safety wire holes. The probe connector also has a removable collar to aid cable routing in tight spaces.
