Description

330851-02-000-066-10-00-00 is a 3300 XL 25 mm proximity probe configured with an M30x2 metric threaded case (Option 02), 0.0 mm unthreaded length (Option 000), 66 mm overall case length (Option 066), 1.0 m total length (Option 10), unarmored cable (Option 00), and standard approvals (Option 00).

This eddy-current displacement probe is used for non-contact, large-target measurements like steam turbine differential expansion or rotor axial thrust position. Combining a front-and-rear sealing design with standard perfluoroalkoxyethylene (PFA) insulated FluidLoc cable, it prevents moisture ingress into the probe tip. High-temperature ClickLoc connectors are standard and feature a removable collar on the probe lead female connector to simplify installation inside tight conduit clearances.

Features

Threaded Case: Option 02 provides a metric M30x2 threaded housing made of AISI 304 stainless steel.
Unthreaded Length: Option 000 provides a fully threaded case length of 0.0 mm.
Case Length: Option 066 provides a 66 mm overall case length.
Total Length: Option 10 supplies a 1.0 metre (3.3 feet) integrated FluidLoc cable.
Armor Option: Option 00 specifies a standard non-armored probe cable structure.
Moisture Sealing: Features a Viton O-ring and compression seal at the probe tip.
Easy Routing: ClickLoc connector has a removable collar that allows the lead to be routed through small clearances.

Applications

Steam turbine differential expansion (DE) measurements.
Steam turbine rotor axial thrust position monitoring.
Reciprocating compressor rod-drop style monitoring.
Large shaft target displacement and axial position measurements.

Installation Guidelines

Ensure the target size is at least 61 mm (2.4 in) flat diameter to maintain standard linear range performance.
Thread the M30x2 probe case into the bracket and secure it using the predrilled locknut with safety wire.
Do not exceed the maximum rated installation torque of 163 N-m (120 ft-lb). A torque of 68 N-m (50 ft-lb) is recommended.
Connect the probe lead to the 3300 XL extension cable finger-tight, up to a maximum torque of 0.565 N-m (5 in-lb).

Compliance and Certifications

European CE Mark: Compliant with applicable directives when used in standard installations.
