Quick Detail

Description

The 3500/53 133388-01 Electronic Overspeed Detection System is engineered for precise overspeed monitoring in automated machinery. Part of the Bently Nevada 3500 Series, the 3500/53 133388-01 accepts a single transducer signal from proximity probes or magnetic pickups, with an input range of +10 V to -24 V and 20 kΩ impedance. Typical power consumption is 8 W. The 3500/53 133388-01 provides 4–20 mA recorder output proportional to full-scale speed (rpm), with a resolution of 0.3662 µA per bit and update rate near 100 ms. SPDT relays support under-alert, over-alert, and danger (overspeed) setpoints adjustable via software, with alarm response under 30 ms above 300 Hz. Transducer supply delivers -24 Vdc at 40 mA, and output impedance is 550 Ω. Front panel LEDs indicate module status, bypass, test mode, and alarms. Operating range spans -30°C to +65°C, with 95% non-condensing humidity. Multiple 3500/53 133388-01 modules can form 2-of-2 or 2-of-3 voting configurations in a 3500 rack with redundant power. Designed for direct integration into automated overspeed protection systems, the 3500/53 133388-01 ensures precise, rapid detection critical for high-speed machinery control.

Applications

High-Speed Turbine Overspeed Monitoring
The 3500/53 133388-01 monitors turbine shaft speed using proximity probes or magnetic pickups. It provides 4–20 mA output proportional to full-scale rpm, allowing automated shutdown or alert when speed exceeds configured thresholds.

Compressor and Pump Overspeed Protection
In automated pump and compressor systems, the 3500/53 133388-01 triggers SPDT relay alarms under over-alert and danger conditions. Alarm response occurs in less than 30 ms above 300 Hz, ensuring rapid protection for rotating equipment.

Automated Machinery Voting Systems
Multiple 3500/53 133388-01 modules can form 2-of-2 or 2-of-3 voting configurations in a 3500 rack with redundant power supplies, enabling automated decision-making for critical overspeed shutdown operations.

Recorder and Data Logging for Control Systems
The 3500/53 133388-01 provides high-resolution recorder outputs (0.3662 µA per bit) updated every 100 ms, facilitating integration into SCADA or DCS systems for automated speed monitoring and logging.

Specifications
