Quick Detail

Description

The 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe features a 230 mm overall case length, M30x2 threaded case, and a 5.0-metre armored extension cable for automated turbine monitoring applications. Constructed from AISI 304 stainless steel with a PEEK probe tip, the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe delivers 0.787 V/mm output and a 12.7 mm linear range, ideal for measuring differential expansion (DE) in midsize to large steam turbine rotors. The probe’s vertical adapter travel of 25.4 mm enables precise rotor axial movement tracking, while front and rear seals prevent moisture ingress for reliable automated measurements. The armored 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe withstands continuous operation from -35°C to +200°C and intermittent spikes up to +250°C. Compatible with 3300 XL Proximitor Sensors, it allows seamless system upgrades without monitor reconfiguration. ClickLoc connectors and optional flexible SST/PFA armor simplify installation and routing in tight industrial spaces. The 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe supports automated data acquisition, DE monitoring, and turbine retrofits with long-distance signal transmission.

Applications

Measure Differential Expansion in Steam Turbines
Use the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe to monitor axial movement between the turbine rotor and stator. Its 12.7 mm linear range and 0.787 V/mm output enable precise differential expansion (DE) measurements, reducing manual inspection needs.

Rotor Axial Displacement Monitoring
Install the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe with its 25.4 mm vertical adapter travel to track rotor axial movement in midsize and large generators for real-time data capture.

Long-Distance Signal Transmission
With its 5.0-metre armored extension cable, the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe can transmit DE signals over long distances to Proximitor Sensors, enabling centralized automation system integration.

Automated Turbine Retrofits
Replace legacy 7200 DE probes with the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe to upgrade turbine monitoring without changing existing monitor configurations.

High-Temperature DE Environments
Deploy the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe in high-temperature zones (-35°C to +200°C operating, +250°C short-term) to gather continuous data during turbine start-up or high-load operation.

Specifications

Competitive Advantage

Extended Measurement Reach
The 230 mm case and 5.0-metre armored cable of the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe allow placement in hard-to-reach or confined turbine locations while maintaining signal integrity.

Quick and Safe Installation
ClickLoc connectors and a removable collar on the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe facilitate rapid cable routing through tight spaces, reducing installation time and labor.

High-Temperature Operation
Operate the 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe continuously up to 200°C and intermittently up to 250°C, allowing automated DE monitoring in extreme turbine conditions.

Seamless System Upgrade
The 330851-02-000-230-50-01-05 3300 XL 25 mm Proximity Probe matches output specifications of previous 7200 DE probes, enabling direct replacement and automated system upgrades without reconfiguring Proximitor Sensors.
