Basic Information

Brand: Bently
Model: 3500/53 133388-01
Series: 3500
Origin: United States

Functional Features

Self-Diagnosis and Fault-Tolerant Design: Equipped with self-diagnostic capabilities and fault tolerance, supporting multiple redundancy configurations—from adding a second fully redundant power supply to Triple Modular Redundancy (TMR) setups—meeting the requirements of mission-critical applications.
Multi-Sensor Compatibility: Accepts signals from eddy current sensors or magnetic sensors, compatible with Bently 3300 8mm eddy current probes, 3300 16mm High-Temperature Proximity Sensors (HTPS), 7200 Series eddy current probes, 3300 RAM eddy current probes, and magnetic sensors.
High-Precision Measurement: Supports 1 to 255 events per revolution, with a maximum full-scale range of 99,999 rpm. Measurement accuracy varies by speed range:
- ±0.1 rpm for speeds < 100 rpm
- ±1 rpm for speeds between 100 rpm and 10,000 rpm
- ±0.01% for speeds between 10,000 rpm and 99,999 rpm.
Rapid Response: Alarm time delay is less than 30 ms for frequencies above 300 Hz, enabling quick detection of overspeed conditions and output of alarm signals.
Multiple Output Modes: Provides four fast-response alarm relay outputs, with a maximum switching voltage of 30V DC or 250V AC and a maximum switching current of 5A. Contact life is 100,000 operations (at 5A, 24V DC or 120V AC).
Status Indicators: The front panel features multiple LED indicators, including OK, TX/RX, Bypass, Test Mode, and Alarm, which display the module’s operating status, communication status, bypass status, test status, and alarm status.
