Description

The Amphenol Wilcoxon 780B accelerometer is a piezoelectric vibration sensor engineered for continuous condition monitoring in industrial settings. Its robust, hermetically sealed housing ensures reliable performance in harsh conditions, including exposure to moisture, dust, and extreme temperatures. The sensor generates a low-impedance voltage output proportional to acceleration, simplifying integration with PLCs, SCADA systems, and dedicated vibration analyzers.

Based on a shear-mode piezoelectric sensing element, the 780B provides a stable, low-noise signal across its specified frequency range, making it ideal for tracking bearing wear, imbalance, misalignment, and other mechanical faults. The integrated 1/4-28 UNF mounting stud guarantees a rigid mechanical coupling to the monitored asset, which is critical for accurate high-frequency response and long-term measurement integrity.

Key Features

  • Piezoelectric shear-mode design for stable, low-noise output and high-frequency response.
  • Hermetically sealed, ruggedized stainless steel housing for durability in harsh industrial environments.
  • Wide operating temperature range (-50°C to 120°C) ensures performance in extreme thermal conditions.
  • Standard 1/4-28 UNF threaded mount provides a secure, industry-standard mechanical interface.
  • Low-impedance voltage output (0.1 V/g) simplifies direct connection to most industrial data acquisition systems.
  • Two-wire constant current power (4-20 mA loop compatible) for easy integration into existing monitoring networks.
  • Optimized for permanent installation and long-term reliability in predictive maintenance programs.

Applications

  • Continuous vibration monitoring for predictive maintenance on motors, pumps, fans, and compressors.
  • Condition-based asset management in manufacturing plants, power generation facilities, and oil & gas operations.
  • Structural health monitoring and vibration analysis on rotating machinery and heavy industrial equipment.
  • Integration into PLC and SCADA systems for automated alarm triggering based on vibration thresholds.
  • Machinery protection systems to prevent catastrophic failure by detecting early signs of imbalance or bearing wear.

Frequently Asked Questions

What is the power supply requirement for the Amphenol Wilcoxon 780B accelerometer?

The 780B operates on a two-wire, constant current power supply typically between 18-30 VDC, which is standard for industrial 4-20 mA loop systems. It requires an external constant current source, often provided by a compatible vibration transmitter or data acquisition module. The sensor draws a nominal 4 mA current for operation.

How do I mount the 780B sensor to my equipment?

Mount the sensor using the supplied 1/4-28 UNF threaded stud. Ensure the mounting surface is clean, flat, and free of paint or debris to guarantee a rigid mechanical bond. A proper mount is critical for accurate high-frequency vibration measurement. For permanent installations, adhesive or magnetic mounts are not recommended; direct stud mounting is required.

What type of output signal does this accelerometer provide?

The 780B provides a low-impedance analog voltage output with a sensitivity of 0.1 volts per g of acceleration. This voltage signal can be directly connected to the analog input of most data acquisition systems, PLCs, or vibration analyzers. The output is proportional to the vibration acceleration measured along the sensor's primary axis.

Is the Amphenol Wilcoxon 780B suitable for outdoor or harsh environment use?

Yes, the 780B is designed for harsh industrial environments. Its hermetically sealed stainless steel housing provides protection against moisture and contaminants. With an operating temperature range of -50°C to 120°C, it is suitable for outdoor installations and extreme temperature applications common in power generation, mining, and heavy manufacturing.
