Applications And Installation Checks

Monitoring machinery where the front of the probe is exposed to aggressive chemicals, anhydrous ammonia or extreme-pH media.

Non-contacting position and vibration measurement with a compatible 3300 Proximitor sensor and extension cable.

Applications requiring a ceramic-to-metal front seal and the manufacturer-stated 34 bar pressure rating.

Confirmed Compatibility Conditions

✓Use the 146054 forward-mount, 3/8-24 UNF probe with the matching 3300 Proximitor sensor and extension cable.

✓The rear of 146054 is not sealed; do not expose it to water, ammonia solutions, hydrogen sulfide or other destructive environments.

✓Gap the ceramic tip electrically and avoid direct mechanical contact with the target; the ceramic-probe linear range is shifted from a standard 3300 XL probe.

✓Match the 2.0 m integral probe length to the required total system length and confirm target material calibration.

Approval And Documentation Check

Option 05 specifies CSA, ATEX and IECEx. The exact site certificate, installation drawing and hazardous-area conditions must be confirmed for the supplied unit.

Lifecycle And Replacement Guidance

The current manufacturer datasheet does not identify 146054-34-20-02-05 as discontinued and does not name a universal replacement. Any change must preserve thread, case length, total length, connector, pressure seal, target calibration and approvals.

Frequently Asked Questions

Where can 146054-34-20-02-05 be used?

It is intended for installations where the probe front may contact corrosive gases or liquids; its rear must remain protected.

Is the rear of 146054-34-20-02-05 sealed?

No. The 146054 design seals the front ceramic-to-metal interface, while the rear has no sealing fitting or stainless-steel tube.

What pressure and temperature limits apply to 146054-34-20-02-05?

The manufacturer lists a 34 bar nitrogen seal rating and -51°C to +177°C operating and storage range.

What gap should be used for 146054-34-20-02-05?

The recommended electrical gap is 1.0 mm, with a stated 1.52 mm linear range.

Can a standard 3300 XL probe directly replace 146054-34-20-02-05?

Do not assume that. The ceramic cap, shifted linear range, chemical exposure requirements, thread, length and approval conditions must all be reviewed.

Model Identification

Use the complete identifier 146054-34-20-02-05. Hyphen placement, zero padding, XX or XXX positions and MOD references are significant. Similar-looking codes can identify different dimensions, cable lengths, fittings, mounting details, approvals or controlled modifications.
