Frequently Asked Questions
Why does the 50 mm probe utilize a triaxial FluidLoc cable instead of a standard coaxial cable?
The triaxial FluidLoc design prevents steam and moisture from migrating through the cable core into the probe tip under high-temperature steam turbine operating conditions.
What is Global PLC Spare HUB's Insight on handling ClickLoc connectors during installation?
Global PLC Spare HUB recommends utilizing the included disposable connector protector tool and removable collar to protect the contacts and route the cable smoothly through tight machinery clearances.
How should technicians manage the side-exit mounting configuration during setup?
Secure the probe using the two ¼-20 mounting holes located on the rear of the 1.99-inch case, ensuring proper torque alignment to prevent side-load stress.
What precautions are required when exposing the sensor to short-term temperature spikes?
Ensure short-term excursions up to +250°C do not exceed a cumulative duration of 24 hours to prevent permanent thermal degradation of internal insulation.
How can I verify the electrical integrity of a 5.0-meter 50 mm probe prior to startup?
Measure the DC resistance between the center conductor and coaxial shield; a stable reading matching the 7.6 ± 0.8 Ω specification confirms zero internal breaks.
