Frequently Asked Questions
What applications require a 7.8-inch long probe?
This length is needed when the measurement point is deep inside a machine, such as through a thick bearing housing, a long sleeve, or a deep access port on large turbines or compressors.
What is the purpose of the 0.4-inch unthreaded section?
The short unthreaded portion at the tip helps center the probe in the mounting hole before the threads engage. This ensures the probe is straight for accurate gap setting.
Is the long armored case more flexible or prone to bending?
The armored construction provides excellent rigidity. While long, it is designed to resist bending, maintaining alignment even in extended installations.
What is a key installation tip for long probes?
Support the probe body during installation. For very long probes, avoid letting it cantilever unsupported, as this can misalign the tip and damage threads.
How do I choose between long armored and long standard probes?
Choose the armored version (330102-04-78-05-02-05) if the long probe will pass through an area with potential for physical contact or abrasion. If the path is clear, a standard long probe may be suitable.
