Description
The 3300 XL 8 mm Proximity Transducer System consists of: o One 3300 XL 8 mm probe, o One 3300 XL extension cable1, and o One 3300 XL Proximitor Sensor2.
The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements3.
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components.
Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable4 with other non XL 3300 series 5 mm and 8 mm transducer system components5. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space6,7.
Proximitor Sensor
The 3300 XL Proximitor Sensor incorporates numerous improvements over previous designs. Its physical packaging allows you to use it in high-density DIN-rail installations. You can also mount the sensor in a traditional panel mount configuration, where it shares an identical 4-hole mounting “footprint” with older Proximitor Sensor designs. The mounting base for either option provides electrical isolation and eliminates the need for separate isolator plates. The 3300 XL Proximitor Sensor is highly immune to radio frequency interference, allowing you to install it in fiberglass housings without adverse effects from nearby

Description
3500 Internal Barriers are intrinsically safe interfaces that provide explosion protection for transducer systems connected directly to the 3500 Machinery Protection System. The internal barriers are fully compatible with the 3500 System and provide a convenient and cost-effective solution for installing all types of transducer systems within a hazardous area.
The internal barriers are fully compatible with the 3500 System and provide a convenient and cost-effective solution for installing all types of transducer systems within a hazardous area
Unlike external barriers, 3500 Internal Barriers are an integral part of the 3500 System and will not degrade the system’s performance.  
We offer Bently Nevada transducer systems with comprehensive approvals for hazardous area installations. The transducer systems are matched to those of the 3500 Internal Barriers. See Compatible Monitors and Transducers on page 8.

Each component complies both individually and as part of a system with the safety requirements of North American and international standards.  Hence, you don’t have to reference individual certificates to verify the compatibility between components.
Standard and internal barrier monitors can reside within the same 3500 rack. You can upgrade standard monitors  by replacing existing I/O modules with those that contain internal barriers
Installation Guidelines
The internal barriers for a 3500 rack are incorporated in special Monitor I/O Modules.   These barriers provide explosion protection for transducer systems that are connected to the 3500 system.  An intrinsically safe (IS) earthing module provides the IS earth connection through the 3500 system backplane. The IS Earth Module requires a dedicated I/O module position and precludes the use of this monitor position for other 3500 System modules.  This limits a standard 19-inch rack to 13 monitor positions.  Furthermore, a number of installation options are not available when internal barriers are installed in a 3500 rack.For users who need to know or purchase such equipment, they can contact the supplier for more information by email itadcs@163.com or WhatsApp message +86 17750019513.

Core characteristics
4-channel independent monitoring

Static value parameters (such as peak-peak value, GAP voltage, etc.) can be configured independently for each channel.
High precision signal conditioning
Adapted to Bently Nevada eddy current sensor (such as 3300/7200 series), with input range of -2V to -18V DC.
Dynamic signal processing ensures high resolution measurement (typical accuracy 1% fs).
Flexible alarm configuration
Each channel supports two-level alarm (Alert/Danger), and the threshold is programmable.
Can be associated with static values (such as 1X amplitude and phase) to trigger protection logic.
Modular extended design
Plug and play installed in 3500 rack (compatible with 125388-01 chassis).
Through the rapid configuration of 3500 configuration software, it supports hot plug maintenance.

The 3500/92 Communication Gateway module provides extensive communication capabilities of all rack monitored values and statuses for integration with process control and other automation systems using both Ethernet TCP/IP and serial (RS232/RS422/RS485) communications capabilities.  It also permits Ethernet communications with 3500 Rack Configuration Software and Data Acquisition Software.
Supported protocols include:
l Modicon Modbus protocol (via serial communications) 
 l Modbus/TCP protocol (a variant of serial Modbus used for TCP/IP Ethernet communications) 
 l Proprietary Bently Nevada protocol (for communication with 3500 Rack Configuration and Data Acquisition Software packages)

The 3500/92 supports the communication interfaces, communication protocols, and other features from the original 3500/90 with the exception of the primary value Modbus registers.  The 3500/92 now has a Configurable Modbus Register Utility, which can provide the same functionality originally addressed by the primary value Modbus registers.

Description
Thermal Case Growth Measurements in Large Turbines

An important position measurement in Turbine Supervisory Instrumentation (TSI) is case expansion. Case expansion (sometimes referred to as shell expansion) is the thermal growth of the machine case as it expands during machine startup and on-line operations.  The case expansion transducer system is typically mounted on the foundation at the opposite end from where the turbine casing is attached to the foundation and provides information about the growth of the machine case relative to the foundation.
Case expansion is a parameter that you should use a dual transducer arrangement to measure.  This arrangement provides information about the position of the sliding feet on the machine case.  A condition that obstructs or jams one foot could distort the case and damage the machine.  The dual case expansion transducer configuration in conjunction with the 3300 or 3500 monitors provides an alarm for this condition.  The high temperature dual case expansion transducer configuration is compatible only with the 3500/45 Position Monitor.
Case expansion measurements also enable you to determine whether machine conditions are exceeding expected temperature growth differentials.  This is primarily a startup parameter that determines whether the machine casing and rotor grow thermally at nearly the same rate.  Different rates of thermal growth can cause the rotating and stationary parts of the machine to rub.
The case expansion transducer assembly consists of a linear variable differential transformer (LVDT), which is housed in a weatherproof, protective enclosure.
How a Case Expansion Transducer Works
The case expansion transducer system uses the LVDT to measure the machine case thermal growth.

A rod on the LVDT connects to the machine.  As the machine case grows, the rod moves inside the LVDT and changes the signal in the LVDT.  The transducer electronically conditions the signal and outputs it to a monitor for display

Bently Nevada’s Electronic Overspeed Detection System for the 3500 Series Machinery Detection System provides 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 Standards 670 and 612 pertaining to overspeed protection.

3500/53 modules can be combined to form a 2-out-of-2 or 2-out-of-3 (recommended) voting system.

The use of redundant power supplies in a 3500 rack containing the Overspeed Detection System is required.
