Bently Nevada 3500/53 Overspeed Detection I/O Module 133396-01 The primary purpose of the Dynamic Input module is to digitize the sensor  signal at a rate that completely encompasses the signal content and  provides transducer power for various sensors. The Orbit 60 Series Dynamic  Input module is a 4-channel input module available in both negative and  positive dynamic input options. The inputs are also used for speed or  Keyphasor signals.

Features:Highly Reliable

Fast Response

Combines to Form a 2-Out-Of-2 or 2-Out-Of-3 Voting System

The GE / Bently Nevada 3500/53 Series Electronic Overspeed Detection Systems for the 3500 Series Machinery Detection System provide a highly reliable, fast response, redundant tachometer system intended specifically for use as part of an overspeed protection system. It is designed to meet the requirements of American Petroleum Institute (API) Standards 670 and 612 pertaining to overspeed protection. The 3500/53 modules can be combined to form a 2-out-of-2 or a 2-out-of-3 (recommended) voting system. The Overspeed Detection System requires the use of a 3500 rack with redundant power supplies.

Bently Nevada 3500/53 was a privately held US corporation between 1961 and 2002, during which time it pioneered the eddy-current proximity probe, a sensor that revolutionized the measurement of vibration in high-speed turbomachinery by allowing the direct observation of the rotating shaft. The company also performed significant research in the field of rotordynamics, furthering knowledge of machinery malfunctions such as shaft cracks and fluid-induced instabilities. Its research also helped refine the equations used to describe vibratory behavior in rotordynamic systems.

The 3500TMR configuration performs the monitor voting function by selecting the install function of the MONITOR option. In this way, the TMR TDI continuously compares the output of the three redundant monitors. If the TMR TDI detects that the output of one monitor is not equal to the output of the other two monitors (within a percentage of the configuration), it issues an error indication to the monitor.

Orbit 60 Series Chassis 

You can flexibly deploy each chassis option with a public facing side (for rack or panel mounts) and a  utility side (for wiring connections and bulkhead mounts). Insert modules and make all wiring  connections from the utility side. 3500/45 Provisions for the public side of the chassis include status LEDs,  configuration port, Config/Run key, and reset button. Three chassis types are available.

Chassis Types

Mounting Options 

l Panel Mount – Mounts to rectangular cutouts in panels and secures to the panel using clamps  supplied with the chassis in 3U Mini*, 3U 19" standard, and 6U 19" standard* configurations. The  6U 19" will fit in the space of a 3500/53 rack.

l Rackmount – Mounts the 3U or 6U chassis on 19-inch EIA rails. Two 3U units or a single 6U* form  factor have been designed to fit within the space of a single 19” rackmount 3500 unit, as a  retrofit. 

l Bulkhead - Typically mounts into a protective enclosure fastened to a sub panel in 3U Mini*, 3U  19" standard, and 6U 19" standard* configurations. NEMA 4 and 4X weatherproof housings are  available when required for environmental protection or when purge air is used.
