Introduction

The model 330101-30-63-10-02-CN is a 4-20 mA DC Velocity Seismic Transmitter from the Bently Nevada 3300 series, configured for the Chinese market (as denoted by the -CN suffix). This device is designed to measure the casing or absolute vibration (expressed as velocity) of rotating machinery. It integrates a piezoelectric accelerometer with internal signal conditioning electronics to produce a standardized, loop-powered 4-20 mA output that is directly proportional to vibration severity. The specific suffixes define its unique configuration: a high-sensitivity accelerometer (-30), a very low-frequency response for slow-speed machinery (-63), and specific connector/cable details (-10-02).

Parameters / Specifications

The following table outlines the key technical parameters for the 330101-30-63-10-02-CN transducer.

*Note: The dimensions and weight are typical values for this model series. The critical differentiator for this model is its low-frequency response (down to 1.0 Hz), made possible by the high-sensitivity internal element. Always verify against the official manufacturer's datasheet for the precise configuration.*

Application Scenarios

This specific transmitter is specialized for applications involving low-speed machinery where low-frequency vibration is the primary concern.

1. Low-Speed Rotating Machinery:

• Ideal for monitoring very slow-speed equipment such as large dam gates, kilns and rotary furnaces, slow-speed large pumps, and some types of mixers, where the fundamental vibration frequency is below 5 Hz (300 CPM).

2. Structural Vibration Monitoring:

• Used to monitor absolute vibration on large, massive structures that vibrate at very low frequencies, such as wind turbine towers, large frames, and foundations supporting heavy machinery.

3. Condition Monitoring for Heavy-Duty Equipment:

• Perfect for the mining, mineral processing, and cement industries, where massive, slow-rotating equipment like ball mills, crushers, and draglines operate and require reliable vibration data for predictive maintenance.

4. Integration with Chinese Control Systems:

• The -CN designation makes it suitable for direct integration into projects and control systems within China, ensuring compliance with local standards and requirements.

5. Predictive Maintenance on Low-RPM Assets:

• Enables effective predictive maintenance programs for assets that traditional vibration transmitters (with a typical 4.5 Hz lower limit) cannot accurately monitor, allowing for the early detection of imbalance and mechanical issues in slow-speed applications.
