Bently Nevada 3500/53 | Electronic overspeed detection system

Bently Nevada 3500/53 electronic overspeed detection system.

· Input signal: Accept a single sensor signal from a proximity probe sensor or magnetic pickup, with an input signal range of ± 10.0V to -24.0V (internal limit) and an input 

impedance of 20k Ω.

· Power consumption: The typical power consumption is 8.0 watts.

· Sensor compatibility: Compatible with Bently Nevada 3300, 7200 type preamplifiers and magnetic pickups.

· Output: The front panel has LED indicators such as OK, TX/RX, bypass, test mode, and alarm; Buffer sensor output is a coaxial connector for short circuit and ESD protection; 

The recorder output is+4 to+20mA, proportional to the module's full-scale range (rpm), and the voltage compliance range is 0 to+12VDC.

· Resolution and update rate: The resolution is 0.3662 µ A per bit, with an error of ± 0.25% at room temperature and ± 0.7% within the temperature range. The update rate is 

approximately 100ms.

· Relay: Single pole double throw (SPDT) relay, epoxy resin sealed, standard configuration with arc extinguisher, maximum switching power DC 120W, AC 600VA, maximum 

switching current for resistive load 5A, minimum switching current 100mA@5VDC The maximum switching voltage DC is 30VDC, AC is 250VAC, and the contact life is 100000 

cycles @ 5A, 24VDC or 120VAC.

· Frequency response speed input: supports 1 to 255 events per revolution, with a maximum full-scale range of 99999rpm and a maximum input frequency of 20kHz.

· Overspeed Protection: Provides highly reliable and responsive redundant tachometer systems for industrial machinery, used for overspeed protection. When the speed of 

the equipment exceeds the set safety threshold, it can detect and issue alarm signals in a timely and accurate manner, triggering corresponding protection mechanisms such 

as emergency shutdown, to prevent serious damage to the equipment due to overspeed, such as shaft fracture, impeller rupture, etc., meeting the requirements of American 

Petroleum Institute (API) standards 670 and 612 for overspeed protection.

· System redundancy configuration: 2 out of 2 or 3 out of 2 (recommended) voting system can be combined to improve the reliability and safety of the system, ensure the 

stability and reliability of overspeed detection function during the operation of key equipment, and reduce the occurrence of false alarm or missing alarm caused by single 

module failure.

· Speed monitoring and control: Real time monitoring of the speed of rotating equipment, converting the speed signal into a standard electrical signal output, which can be 

integrated with other control systems or devices to achieve precise control and adjustment of equipment speed, ensuring that the equipment operates within the optimal 

speed range, improving equipment efficiency and stability, and extending equipment service life.
