III. Performance Characteristics
The 1900/65A-01-01-01 excels in performance metrics, making it a reliable choice for industrial monitoring. 3500/32M
A. Frequency Response and Accuracy
Frequency response ranges from 0.1Hz to 10kHz, with an accuracy of ±0.5% of full scale. This wide range ensures accurate measurement of both low-frequency vibrations and high-frequency signals. Phase response is linear within ±1° up to 1kHz, critical for phase-sensitive applications.
B. Resolution and Dynamic Range
The device offers 16-bit resolution, providing precise measurement of small signal variations. Dynamic range is 90dB, enabling detection of both high-amplitude and low-amplitude signals without saturation or loss of detail.
C. Sampling Rate and Data Logging Capabilities
Sampling rates up to 100kHz ensure high-resolution data capture. Built-in data logging supports up to 1GB of storage, with configurable sampling intervals from 1ms to 1 hour. Data can be exported in CSV or binary format for offline analysis.
IV. Alarm Logic and Configuration
Effective alarm management is a cornerstone of the 1900/65A-01-01-01's design, ensuring timely response to abnormal conditions.
A. Alarm Types and Thresholds
The system supports multiple alarm types, including high, low, and rate-of-change alarms. Thresholds are user-configurable, with options for absolute or relative values. Alarm deadbands prevent chatter during transient conditions.
B. Time Delays and Hysteresis
Configurable time delays (0-60 seconds) allow for filtering of transient signals. Hysteresis settings prevent alarm flapping by requiring a defined return-to-normal threshold before resetting the alarm.
C. Alarm Reset and Acknowledge Options
Alarms can be reset manually via the interface or automatically after a defined period. Acknowledge options include local (panel) and remote (SCADA) acknowledgment, ensuring operators are always aware of alarm states.
