BENTLY NEVADA 3500/53 133388-01 Overspeed Detection Module
Description
The BENTLY NEVADA 3500/53 133388-01 Overspeed Detection Module is a high-performance component in the BENTLY NEVADA 3500 series, designed for real-time monitoring and protection of rotating machinery. It simultaneously tracks rotational speed and vibration signals, triggering alarm notifications to safeguard equipment when overspeed or abnormal operating conditions are detected. Key technical specifications include an input signal range of +10.0V to -24.0V, 24V DC operating voltage, and an operating temperature range of -40 degrees Celsius to 85 degrees Celsius. It offers multiple output options including relays and analog signals such as 4-20mA, with a fast response time of ≤1ms, and features an RS485 communication interface and IP67 protection rating. Measuring 120mm x 80mm x 40mm and weighing 200g, the module provides a speed measurement range of 0–100,000 rpm with ±0.1% accuracy, and selectable vibration detection ranges of ±5g, ±10g, ±20g, or ±50g. Equipped with advanced diagnostic functions and flexible configuration options, it can be combined into 2-out-of-2 or 3-out-of-2 (recommended) voting systems, and meets American Petroleum Institute (API) standards 670 and 612 for overspeed protection. Ideal for use in oil and gas refineries, power plants, chemical processing plants, and manufacturing facilities, it integrates easily with existing systems when paired with a 3500 rack with redundant power supply.
