Quick Detail

Description

The 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe features an M39x1.5 threaded case with a 70 mm overall length and 25.4 mm probe adapter travel. Designed for automation in steam turbines, the 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe outputs 0.787 V/mm (20 mV/mil) over a 12.7 mm linear range, enabling precise differential expansion monitoring between rotor and stator. The probe’s AISI 304 stainless steel case and PEEK tip support continuous operation from -35°C to +200°C, and short-term exposure up to +250°C. Combined with a 1.0-metre extension cable and 3300 XL Proximitor Sensor, the 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe allows accurate axial shaft measurements, easy cable routing, and rapid verification via ClickLoc connectors with removable collars. Its design supports installation in tight turbine spaces, side or rear exit configurations, and straightforward integration with existing 7200 and 3300 XL systems, enabling automated monitoring and system upgrades without rewiring.

Applications

Measuring Differential Expansion on Steam Turbines
The 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe monitors differential expansion (DE) by measuring rotor-to-stator movement. Its 0.787 V/mm output and 12.7 mm linear range allow precise DE calculations on midsize to large turbines.

Axial Shaft Displacement Monitoring
With a 25.4 mm probe adapter vertical adjustment and a 1.0-metre extension cable, the 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe measures axial shaft movement and compensates for thermal growth in real-time, supporting automated control and turbine protection systems.

Integration with Existing Transducer Systems
This 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe can replace 7200 or older 3300 XL 25 mm probes, allowing seamless upgrades without reconfiguring the monitor or sensor layout.

High-Temperature Environment Sensing
The 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe operates continuously from -35°C to +200°C and tolerates short-term spikes to +250°C, enabling deployment in high-heat automation zones.

Specifications

Competitive Advantage

Fast Installation and Verification
The ClickLoc connectors and removable collar of the 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe allow quick routing, alignment, and verification of probe placement in tight turbine areas.

Durable High-Temperature Materials
The 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe uses AISI 304 stainless steel and a PEEK tip, providing long-term operation in high-temperature DE applications, and preventing moisture ingress through front and rear seals.

Flexible Mounting Options
The 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe supports M39x1.5 threaded cases or smooth 1.06 in diameter side exits, making it adaptable for various turbine layouts while maintaining a 25.4 mm vertical travel range.

System Upgrade Without Rewiring
Using the 330851-06-000-070-10-00-CN 3300 XL 25 mm Proximity Probe, older DE measurement systems can be upgraded while retaining existing Proximitor Sensors, reducing automation downtime and installation effort.
