Overview

The PROVIBTECH TM0180-07-02-07-05-02 is a high-precision armored Proximity Probe for non-contact measurement of shaft displacement and vibration. Using the eddy current principle, it provides a voltage output proportional to the gap between the probe tip and the shaft. The stainless steel armor (code 02) protects the integral cable from abrasion, impacts, and crushing, ensuring reliable long-term operation in harsh industrial environments. This makes it ideal for API 670-compliant machine protection systems.

Technical Specifications

Applications

The TM0180-07-02-07-05-02 is ideal for mechanically demanding environments, such as areas near sharp edges, maintenance traffic, or falling debris. Typical installations include pump trains, fans, mixers, and large turbines. The 11 mm tip diameter is preferred for larger shafts or slow-speed machinery, offering a stable, representative vibration signal. The armored cable ensures continuous, reliable monitoring under physical stress.

Frequently Asked Questions (FAQ)

Q1: What is the purpose of the stainless steel armor?

A: It protects the probe’s internal cable from abrasion, minor impacts, and crushing, preventing signal degradation or failure.

Q2: Does the armor affect measurement accuracy?

A: No. The armor is electrically shielded and does not interfere with the probe’s API 670-standard 8 mV/µm sensitivity.

Q3: Why choose an 11 mm tip diameter over 8 mm?

A: The larger tip provides a bigger measurement area, which improves signal stability and averaging, especially on large or imperfect shafts.

Q4: How does the probe connect to the monitoring system?

A: It connects to a Proximity Probe Driver via the reverse-mount connector (code 02), which powers the probe, conditions the signal, and outputs a voltage proportional to the shaft gap.
