Features:
- Uses a 1/2-20 straight-exit threaded case with safety-wire locknut.
- Provides a 5.0 m high-temperature FluidLoc cable protected by armor.
- Carries the multiple-approval ordering option for the defined 50 mm system configuration.
The current ordering configuration is 330876-01-50-01-05, the 1/2-20 threaded, 5.0 m, armored FluidLoc 50 mm probe with multiple approvals.
It converts extended axial target movement into the probe signal used by a matching Proximitor Sensor for turbine differential-expansion monitoring.
Before fitting the probe, confirm thread depth, safety-wire practice, cable support, approval markings, five-metre sensor compatibility and target calibration.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Monitors differential expansion on large steam turbine generators with direct threaded probe mounting.
- Provides a protected lead for routes exposed to mechanical contact or maintenance activity.
- Supports approved 50 mm transducer installations that require the 05 ordering option.
- The five-metre probe is designed for the five-metre 3300 XL 50 mm Proximitor Sensor.
- Probe, extension cable and sensor must all belong to the 3300 XL 50 mm component family.
- The nominal calibration assumes an AISI 4140 steel target of at least 102 mm diameter.
- High-temperature construction supports 200 C continuous probe operation and 250 C intermittent exposure.
- FluidLoc limits process liquid movement through the cable interior.
- The 05 suffix identifies the multiple-approval option; apply only approvals present on the delivered label.
- Secure the threaded case with the supplied locknut and project-approved safety wiring.
- Support the armored lead so vibration and bend load are not transferred to the probe body.
- Isolate the monitored machine and confirm safe target clearance before any gap adjustment.
