COMMTEST 220 Description
The Bently Nevada COMMTEST 220 is a portable vibration data collector designed for advanced machinery
condition monitoring in industrial environments. It is part of the COMMTEST / SCOUT200 family and works in
combination with an industrial handheld device running the Android operating system, delivering a modern,
flexible, and user-friendly diagnostic solution.
This system separates data acquisition hardware from the display and analysis interface, enabling users to operate
the device through an Android smartphone or tablet. The handheld device runs the S1 Collector application,
allowing technicians to collect, view, and analyze vibration data in real time.
Frequently asked questions：
Q1: What is the COMMTEST 220?
A1: The COMMTEST 220 is a portable vibration analyzer running on an Android operating system, used for machinery
condition monitoring and diagnostics.
Q2: What is the COMMTEST 220 AC coupled input range?
A2: It supports an AC coupled range of 16 V peak-to-peak, allowing measurement of dynamic vibration signals.
Q3: What sensor signal range does it support?
A3: It allows a ±8 V sensor output swing (equivalent to ±80 g), suitable for high-range vibration sensors.
Q4: What is the COMMTEST 220 ADC resolution?
A4: The device features a 24-bit ADC, providing high-precision signal acquisition.
Q5: Does it provide sensor excitation?
A5: Yes, the COMMTEST 220 sensor excitation current is configurable at 0 mA or 2.2 mA, supporting different
sensor types.
Product Applications
Predictive Maintenance (PdM): Operators use it to perform routine "route-based" data collection on rotating
machinery (motors, pumps, fans, gearboxes) to identify early signs of bearing wear, misalignment, or imbalance.
On-site Troubleshooting: Its dual-channel capability allows for advanced diagnostics, such as cross-channel phase
analysis, to pinpoint the root cause of excessive vibration.
Harsh Environments: The device is built with an IP65 rating, making it dust-tight and water-resistant, ideal for rugged
factory floors.
Data Integration: Collected data is uploaded to System 1 software for long-term trend analysis and automated
reporting.
Technical Highlights
Channels: 2-channel simultaneous sampling.
Connectivity: Supports Bluetooth for wireless sensors and data transfer to mobile apps (S1 Collector).
Storage: 1GB internal memory for storing large volumes of high-resolution waveforms.
Safety: Available in versions certified for hazardous areas (ATEX Zone 2).
