Description

The Vibro-Meter 444-680-000-411 is a general-purpose vibration sensor designed for continuous monitoring of rotating and reciprocating machinery in industrial environments. The sensor belongs to the CE680 family of piezoelectric accelerometers and incorporates integrated electronics that provide a direct voltage output for connection to machinery monitoring, protection, and diagnostic systems.

The sensor uses a shear-mode piezoelectric sensing element that converts mechanical vibration into a proportional electrical signal. This sensing technology offers excellent measurement stability, low susceptibility to thermal transients, and reliable operation across a wide frequency range. Integrated electronics simplify installation by eliminating the need for external charge amplifiers and allowing direct connection to monitoring equipment.

Overview Manuals Application Notes Product Applications Electrical Installation & Grounding

Features:

  • General-purpose vibration sensor
  • Piezoelectric accelerometer with integrated electronics
  • 100 mV/g output sensitivity
  • Wide frequency response up to 14 kHz
The 444-680-000-411 functions as a signal processing and monitoring module for general-purpose vibration measurement applications. It receives input signals from various vibration sensors including CA series piezoelectric accelerometers, CP series dynamic pressure sensors, and TQ series proximity probes, and processes these signals for integration with VM600 or VM600Mk2 monitoring systems.

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Connector: The sensor features a 2-pin, MIL-C-5015 style output connector. Use a mating connector such as an MS3106F-10SL-4S or equivalent.
Grounding: The sensor's case is internally shielded and isolated from the mounting base to prevent ground loops. Ensure the cable shield is grounded at the signal conditioner or monitoring system end, not at the sensor itself.

Technical notes

With a nominal sensitivity of 100 mV/g and a dynamic range of ±80 g, the sensor is capable of detecting both low-level and high-amplitude vibration events. The wide frequency response enables effective monitoring of machinery conditions such as imbalance, misalignment, looseness, rolling-element bearing defects, gear mesh faults, resonance, and structural vibration.

FAQs

  • What is the 444-680-000-411?

    +
    The Vibro-Meter 444-680-000-411 is a specific configuration of the CE 680 piezoelectric accelerometer designed for harsh industrial environments
  • What cables are used with these sensors?

    +
    The CE 600 series (including replacements) typically pairs with specialized hardened cable assemblies, such as the EC 6xx series, which are designed to withstand extreme temperatures, moisture, and hazardous environments.
  • Are these sensors available for hazardous/explosive areas?

    +
    Yes. The modern replacements are available in standard or Ex (explosion-proof/intrinsically safe) versions to comply with industrial safety regulations.
  • What is the CE680 series, and what does it measure?

    +
    The CE680 series (such as the M511 and M611 models) are piezoelectric accelerometers that convert mechanical vibration or shock into a proportional electrical signal (usually 100 mV/g). They are ideal for spectral analysis and general machinery protection
