Technical FAQs
1. What does the 1900/27‑01 monitor measure?
It measures vibration, typically in velocity or displacement, based on the connected sensor type.
2. What sensors can be connected?
It supports industrial vibration sensors such as accelerometers or seismic probes compatible with the monitor’s input.
3. How are alerts provided?
Alerts are delivered via discrete alarm outputs and can also be interfaced with external control systems.
4. What supply voltage is required?
It operates on a standard industrial DC supply, commonly 18–32 V DC.
5. Can it interface with PLC systems?
Yes — both analog outputs and discrete signals allow integration with PLC, DCS, or machine protection systems.
6. Is it suitable for harsh environments?
Yes — designed for continuous industrial operation and vibration‑prone locations.
7. Does it require calibration?
Periodic calibration or verification is recommended to ensure measurement accuracy and threshold fidelity.
8. Can it be rack or panel mounted?
Yes — its form factor supports standard industrial panel or rack installations.
9. Does it have adjustable alarm thresholds?
Typical configurations allow threshold setting for alarm and danger levels based on the monitored parameter.
10. Can it log historical data?
Some installations may pair the unit with external data loggers or systems to capture trends, though the monitor itself focuses on real‑time measurement and alarm outputs.
