The PR 6423 is a non-contact eddy current transducer with a rugged

construction and designed for extremely critical turbomachinery

applications such as steam, gas, compressor and hydro turbomachinery,

blowers and fans.

The purpose of a displacement probe is to measure position or shaft

movement without contacting the measured surface – the rotor.

In the case of sleeve bearing machines, the shaft is separated

from the bearing material by a thin film of oil. The oil acts as

a dampener and therefore the vibration and position of the shaft

are not transmitted through the bearing to the bearing case.

The use of case vibration sensors is discouraged for monitoring

sleeve bearing machines since the vibration produced by shaft motion

or position is greatly attenuated through the bearing oil film.

The ideal method of monitoring shaft position and motion is by

mounting a non-contact eddy sensor through the bearing, or

inside the bearing, measuring the shaft motion and position

directly.

The PR 6423 is commonly used to measure vibration of

machine shafts, eccentricity, thrust (axial displacement), differential

expansion, valve position, and air gaps.

• Non-contact measurement of static and dynamic shaft displacement

– Axial and radial shaft displacement (position)

– Shaft eccentricity

– Shaft vibration (motion)

• Meets international standards, DIN 45670. ISO 10817-1 and API 670

• Rated for explosive area, Eex ib IIC T6/T4

• Other displacement sensor selections include PR 6422. PR 6423.

PR 6424 and PR 6425

• Select converter, such as CON 011/91. 021/91. 041/91. and cable for

complete transducer system

Features • Cost Effective—Single trip valve construction reduces costs and spare part requirements of those systems using three separate switching valves to perform the failure functions. A single trip valve greatly simplifies piping requirements. • Ease of Mode Conversion—Conversion to any of the fail modes requires only minor hookup changes. • Adjustable Trip Valve—The trip point is adjustable for specific supply pressure requirements. • Reliable Operation—The trip valve design includes large diaphragm areas and few moving parts for efficient performance, minimum maintenance, and long service life. Specifications Available Configurations When supply pressure falls below the trip point, 377D Trip Valve: Fails actuator piston down. Includes check valve and volume tank. 377L Trip Valve: Locks actuator piston in the last position. 377U Trip Valve: Fails actuator piston up. Includes check valve and volume tank. 377CW Trip Valve: Fails fully clockwise to close the valve. Requires check valve and volume tank. Trip valve moves piston to either up/down position and requires actuator configuration for actual clockwise movement. 377CCW Trip Valve: Fails fully counterclockwise to close the valve. Requires check valve and volume tank. Trip valve moves piston to either up/down position and requires actuator configuration for actual counterclockwise movement. All 377 trip valves can be converted to any of the above fail modes with minor hookup changes

Fisher™ 377 Trip Valve Fisher 377 pressure‐sensing trip valves are for control applications where a specific valve/actuator action is required when supply pressure falls below a specific point. When supply pressure falls below the trip point (see figure 1), the trip valve causes the actuator to fail up, lock in the last position, or fail down. When the supply pressure rises above the trip point, the 377 trip valve automatically resets, allowing the system to return to normal operation. The trip valve can be top‐mounted on a manifold, yoke‐mounted, or bracket‐mounted to match the application requirements. 377 trip valves can be used with Fisher 480. 585C, 685. 1061. 1066. 1069. and Bettis™ G Series piston actuators.

◼ Reduce business risks by minimizing process downtime ◼ Save on installation costs ◼ Preserve HART® signals Introduction  If concerns about downtime and wiring costs are preventing you from migrating your Foxboro™ I/A Series 100 I/O to a new DeltaV™ system, consider DeltaV Flex.Connect solutions for Foxboro I/A Series 100 I/O. Benefits  Reduce business risks by minimizing process downtime. This solution brings device signals to DeltaV I/O from existing Foxboro I/A Series 100 Fieldbus Modules (FBMs). Keeping device wires intact accelerates the new system startup, enabling you to rapidly resume production. Save installation costs. Eliminating new device wiring saves money and reduces the risk of errors. Time and material savings are significant. Preserve HART signals. Use HART® Pass-through for complete diagnostics at the DeltaV workstations.

Retain Valuable Intellectual Property  While Improving Control Performance  with Tool Based Database and   Display Analysis Striking a balance between complete reverse engineering and starting design from scratch is achieved by taking a Forward Engineering approach which is enabled by using analysis tools, purpose built for the legacy platform. For Foxboro I/A Series Systems, a tool-set is available for both the control database and FoxView displays. Parsers extract the raw data and sophisticated algorithms produce reports from detailed I/O lists to an assessment of complexity, class-based versus custom code and much more. These outputs are designed to allow engineers to assess reusable code, such as base level loops, motors, valves etc. and complex logic structures which might be improved by redesign in a modern system. For example, the use of equipment modules can make operation, visualization and troubleshooting much easier than “spaghetti” function block code. Tools are transforming some traditional manual workflows into digital workflows which increases project efficiency, ensures the required functionality is achieved with a modern design and reduces the risk of errors or a flawed implementation. For your business, this translates to a faster ramp-up to full production, improved controls, confident operators and maintenance staff.

Maximize capital efficiency With robust processes, tools and with the right technology, Emerson can deliver modernization projects that are low risk and make best use of your capital. We can help manage scope, reduce or eliminate engineering and design work, reduce space requirements, and ultimately deliver the value you should expect from the world’s leading distributed control system. Solutions for Legacy Foxboro   I/A Series Systems Reduce Downtime by Up To 75%   with FlexConnect®: When downtime must be kept to a minimum, FlexConnect solutions allow existing field terminations to remain. This saves time and reduces the cost of rewiring. Solutions are available for both FBM 100 series and 200 series I/O. For FBM 100 series, the nosecones are retained along with the existing field I/O terminations. An adapter is connected to the nosecone and the signals are routed to DeltaV I/O modules via cables which will typically be pre-wired at the factory for the shortest possible cutover.

Emerson’s technology can help DeltaV technology provides unprecedented flexibility to work within the constraints of brownfield projects. Electronic marshalling can be installed almost anywhere, can be highly distributed, and with over 40 I/O wiring options it can handle all the signal types existing in your facility. The PK controller has the capacity to handle all the basic process control functions PLUS advanced control, sequences, state-based control, and batch logic. It can also be deployed in smaller, standalone applications, and with built-in Ethernet based connectivity, it can easily integrate data from 3rd party devices like PLCs and drives and can easily provide data to enterprise applications. Brownfield Solutions On top of this, Emerson has a vast catalog of solutions specifically designed to aid in modernizations. The FlexConnect Solutions portfolio speeds up cutover and avoids re-termination of field wires. Emerson’s Alliance Program includes a portfolio of tested gateways that help phase the transition to DeltaV. And for the software transition, Emerson has a world-class set of tools to enable a modern, maintainable, functional implementation of the control strategy while retaining important intellectual property from the legacy system.
