Product Introduction

Signal:A single transducer signal from a proximity probe transducer or magnetic pickup is accepted by each Overspeed Detection module.

The input signal has a voltage range of +10.0 V to -24.0 V. Signals that exceed this range are internally limited by the module.

Input Impedance: 20 k ohm.

Power Consumption: 8.0 watts, typical.

Transducers: Bently Nevada 3300 8 mm Proximitor 3300 16 mm HTPS, 7200 5 mm, 8 mm, 11 mm, and 14 mm Proximitor; 3300 RAM

Proximitor, or Magnetic pickups.

This setpoint is particularly significant in scenarios where rapid rotational acceleration could result in hazardous overspeed conditions. By

setting this Danger setpoint, operators preemptively safeguard against potential equipment failure, breakdowns, and, most importantly,

any risks to personnel safety.

Configuration through Software: The adaptability and precision of the Module's alarm system are further underscored by its software-

based configuration. Through the power of software, users can fine-tune and customize alarm parameters based on the specific

operational characteristics of the machinery being monitored. This flexibility ensures that the alarm thresholds are aligned with the unique requirements of each application.

Adjustable Alarm Range: One of the hallmark features of the Module's alarm system is its adjustable nature. Users have the freedom to

set alarm thresholds that span the entire spectrum of the module's full-scale speed range. This dynamic range can typically be calibrated

from 0 to 100% of the full-scale speed range, offering granular control over alarm triggers to suit diverse operational demands.

Alarm Time Delays: Timing is of the essence in monitoring systems, and the Module's alarm system addresses this through rapid

response. Alarms are accompanied by a time delay mechanism that ensures swift and accurate notifications. Specifically, when operating

at speeds above 300 Hz, the time delay is less than 30 ms. This lightning-quick response time is instrumental in preventing potential

issues from escalating into critical failures, thus minimizing downtime and optimizing operational continuity.

FREQUENTLY ASKED QUESTIONS

What is 3500/53?

This is a tachometer system, which is designed to detect overspeed in machinery and provide quick response and redundant protection. It was designed and developed by Bentley Nevada Company to meet the overspeed protection requirements of american petroleum institute (API) standards 670 and 612.

What is the recommended configuration?

Bently Nevada suggested configuring 2-out-of-2 or 3-out-of-2 voting system for redundancy protection.

What kind of machinery can this tachometer protect?

It can be used in various machines, including turbines, compressors, pumps, generators and motors.

What do you need for installation?

The overspeed detection system needs a 3500 rack with redundant power supply.

What are the benefits?

Providing quick response and redundant protection against overspeed helps to prevent machine damage and reduce downtime. Its design conforms to industry standards and is very reliable.
