Product features
- Continuous single-point monitoring → provides ongoing visibility of machine or bearing vibration
- ICP accelerometer input → supports standard vibration sensor measurement
- Local numeric display → gives technicians immediate measured condition at the panel
- Green/yellow/red LEDs → provides simple visual status against defined limits
- 4–20 mA output → integrates vibration condition into PLC or DCS systems
- Selectable active/passive current loop → provides flexibility for control-system integration
- Programmable alarm relay → supports separate warning or protection logic
- Velocity and acceleration measurement → supports machine-body and bearing-condition monitoring
- Compact 90 × 53 × 58 mm format → fits applications where cabinet space is limited
- 20–28 V DC supply → suits typical industrial control-power environments
Adash A3900 II is intended for machines where one continuously monitored vibration point provides useful early warning of changing condition. It is a compact alternative to a multi-channel monitoring system when maintenance teams need permanent vibration indication on a specific bearing or machine location. The front panel displays the measured value and uses green, yellow and red LEDs to show condition against configured limits.
The unit accepts an ICP-powered accelerometer and can evaluate acceleration or vibration velocity within defined frequency ranges. A galvanically isolated 4–20 mA current-loop output allows the measured condition value to be transferred to a PLC, DCS or other control system. A programmable alarm relay provides a separate discrete output for warning or shutdown logic defined by the site.
Adash specifies frequency bands of 0.8 Hz–16 kHz and 5–16 kHz for acceleration and 10 Hz–1 kHz for velocity. The unit operates from 20–28 V DC, has selectable active or passive 4–20 mA output and a compact 90 × 53 × 58 mm housing. The monitor is designed around one ICP accelerometer input and local status indication.
Permanent monitoring avoids relying entirely on periodic handheld checks for assets where condition can change between inspection rounds. Integration through 4–20 mA and relay outputs lets maintenance information become part of the plant’s existing control or alarm architecture. AxFlow can help verify sensor selection, signal integration, alarm strategy and replacement requirements.
