• Frequency Response: 0.1Hz-10kHz (-3dB), ensuring stable capture of speed signals in a wide range.

• Alarm Function: Supports 2 levels of programmable alarms (Alarm value, Danger value), alarm delay time adjustable from 0-60 seconds.

• Operating Environment:

• Operating temperature: -40°C to 70°C;

• Storage temperature: -50°C to 85°C;

• Relative humidity: 5% to 95% (non-condensing);

• Vibration resistance: 5g (10Hz-2000Hz), shock resistance: 25g (11ms half-sine wave).

• Mechanical Specifications: Approximately 100mm × 150mm × 35mm (half-height module), weight about 0.3kg.

Functional Features

• High-Precision Measurement: Adopts advanced signal processing algorithms to ensure high-precision speed and phase measurement in a wide speed range, providing reliable data for equipment dynamic analysis.

• Phase Synchronization: Achieves phase synchronization with rotating machinery through keyphasor signals, enabling other monitoring parameters such as vibration and displacement to be correlated with rotation phase, facilitating diagnosis of phase-related faults such as unbalance and misalignment.

• Flexible Alarm Configuration: According to the operating requirements of different equipment, speed upper and lower limit alarm thresholds and delay times can be set through 3500 configuration software to meet diversified protection needs.

• Status Feedback and Self-Diagnosis: Real-time feedback of module operating status (such as signal loss, measurement abnormality) to the 3500 Rack Interface Module (RIM), with complete self-diagnosis function for easy system maintenance.

• Strong Compatibility: Seamlessly integrates with other modules and system software of the 3500 series, supporting transmission of measurement data to upper computers through backplane communication for centralized monitoring and data analysis.
