3. Function and Product Positioning

Core Functions

• Absolute Vibration Measurement: Detects vibration velocity relative to free space (seismic reference), ideal for heavy casings or structures where relative shaft vibration is not accessible.

• Passive Operation: Requires no external power, enabling portable measurements and reducing wiring complexity.

• Broadband Vibration Sensing: Captures 4.5 Hz–1 kHz vibration components, covering imbalance, misalignment, bearing fault, and structural resonance frequencies.

• Low Shock Sensitivity: Moving coil design minimizes response to transient shocks/pulses, ensuring stable readings in harsh industrial environments.

• Long‑Term Stability: Sealed, corrosion‑resistant construction delivers consistent performance over extended service life.

Operational Features

• Two‑Wire Simplicity: Direct connection to monitoring systems via shielded two‑wire cables; no external signal conditioning required.

• Flexible Mounting: Top‑mount connector and M10×1 stud base enable easy installation on flat or curved surfaces.

• Calibrated Orientation: 0°±2.5° mounting angle ensures optimal sensitivity and accuracy.

• Field‑Proven Durability: Withstands high temperatures, humidity, and industrial contaminants; no scheduled maintenance required.

Product Positioning

• API 670‑compliant casing/structural vibration monitoring in turbines, compressors, and generators.

• Portable predictive maintenance surveys (no external power needed).

• High‑temperature environments (up to +121°C) where active sensors may degrade.

• Retrofit projects replacing legacy 74712 or 47633 seismoprobes.

• Applications requiring low shock sensitivity and long‑term stability.

6. Applicable Equipment and Industry Fields

Primary Applications

• Power Generation: Steam/gas turbine casings, generator end bells, and large bearing housings in thermal, combined‑cycle, and nuclear power plants.

• Oil and Gas: Centrifugal compressors, turboexpanders, and pump casings in refineries, LNG facilities, and offshore platforms.

• Petrochemical: Process compressors, reactor agitators, and high‑speed fan casings.

• Heavy Industry: Steel mill rolling mills, large industrial fans, and blowers (structural/casing vibration).

Secondary Applications

• Marine: Ship propulsion turbine/generator casings and auxiliary machinery.

• Pulp and Paper: Large paper machine rolls and dryer casings.

• Mining: Crusher and conveyor drive machinery housings.

• Portable Monitoring: Predictive maintenance surveys on rotating equipment (no external power required).

Compatibility Notes

• Passive Only: No internal electronics; requires compatible monitor with AC voltage input.

• Absolute Vibration: Measures casing/structural vibration, not shaft relative vibration (use proximity probes for shaft vibration).

• High‑Temperature Capable: Suitable for environments up to +121°C; not for cryogenic applications below −29°C.

• Mounting Critical: Performance depends on 0°±2.5° axial mounting; transverse mounting reduces sensitivity.
