Overview

The PROVIBTECH TM0180-07-00-03-05-02 is a high-precision Proximity Probe for continuous shaft displacement and radial vibration monitoring in rotating machinery. Using the eddy current principle, it outputs a voltage proportional to the gap between the probe tip and the shaft. This probe is API 670-compliant and ensures accurate monitoring of radial vibration and axial thrust, making it essential for critical machine protection systems. The model code defines its precise physical dimensions and electrical properties, guaranteeing proper system calibration and reliability.

Technical Specifications

Applications

The TM0180-07-00-03-05-02 is ideal for installations with limited space, such as small steam turbines, high-speed gearboxes, or specialized machine tools. Its 5 mm tip allows precise measurement in tight areas while maintaining high sensitivity. The probe accurately monitors shaft movement and ensures proper thrust bearing clearance, supporting reliable, continuous machinery protection.

Frequently Asked Questions (FAQ)

Q1: How does the 5 mm tip compare to the standard 8 mm tip?

A: The 5 mm tip fits in tighter spaces. Both maintain 8 mV/µm sensitivity, but the smaller tip has a slightly reduced linear range and requires a smaller target surface.

Q2: What is the purpose of the 70 mm unthreaded length?

A: It passes through the machine casing or mounting block, ensuring the tip is correctly positioned over the shaft.

Q3: Does the 5-meter cable represent the total system length?

A: No. The 5 meters is only the probe’s integral cable. The total electrical system (probe + extension + driver) must be 5 m or 9 m to meet API 670 requirements.

Q4: Is a separate power supply required?

A: Yes. Proximity probes are passive and require a Proximity Probe Driver to supply high-frequency power, condition the signal, and output the final DC voltage proportional to the shaft gap.
