PROTECTING ROTATING PLANT


Continuous protection and monitoring is becoming essential for rotating plant to protect processes from unscheduled downtime. To help, Sensonics has developed the compact DN26 G3 protection monitor. This is suitable for smaller plant and equipment such as pumps and fans, as well as small to medium industrial machinery. This DIN Rail mountable unit can


monitor two channels of bearing vibration, shaft vibration, or shaft position and offers fully programmable signal conditioning with a range of measurement algorithms and sensor options. It also offers a dedicated speed monitor channel which can be utilised as a phase reference for harmonic analysis of the vibration signals. As a universal module (single hardware platform) it is also field upgradable.


MONITORING GASES DURING WELD OVERLAY CLADDING


is using the 542 binary gas analyser from Systech Illinois, which provides the ability to accurately check the gas mixture to ensure it is suitable for the application. The analyser is capable of measuring almost


any mixture of gas; and uses a high quality sensor to provide accurate and reliable measurements – assisting the control and regulation of the ideal weld overlay environment. Andrew Robinson, director at Arc Energy,


Arc Energy Resources’ weld overlay cladding provides heavy duty protection against corrosion and wear for process and pipeline equipment used in hostile environments, including offshore oil and gas applications. Different gas mixtures are required for different


types of welding. So, to monitor the mixture of gases during the weld overlay process, the company


explained that the weld overlay cladding process is sensitive to the mix of shielding gas being used. With the analyser, the company is assured that the gas is correct.

Owned and operated by the United Kingdom Atomic Energy Authority, the Culham Centre for Fusion Energy (CCFE) in Oxfordshire hosts what is said to be the world’s largest magnetic fusion experiment, JET (Joint European Torus), on behalf of its European partners. Here, an in-line ultrasonic flowmeter had been used for over 30 years to monitor the flow of the site’s water cooling system which operates in two modes. During ‘Silent Hours’ the flow demand is reduced to 700m3


/h which means that only one of the four main 160kW


pumps is running. ‘Normal Hours’ mode is selected at the start of daily operations when the process opens up various valves on the distribution system. This is achieved with a PLC control system, which monitors flow demand from the in-line ultrasonic flow meter to sequentially control the three other pumps over a 20 minute period until all four pumps are running, providing a total flow of approximately 3500m3


/h. The sensor interface is


programmable to accept IEPE type accelerometers/velometers, proximity probes (API 670 standard), and active/passive speed probes. The unit is available with Ethernet


communications as standard and features a built-in intuitive colour LCD and menu drive facility.

However, the performance of the in-line flow meter was becoming unreliable and when the decision was taken to install a back up system, CCFE turned to Micronics. CCFE had already used a Micronics Portaflow 300 for portable monitoring and was confident a suitable fixed clamp-on meter would be recommended. David Gear, CCFE technician, commented: “It is crucial to have the ability to monitor the cooling process and the flow in the site cooling water circuits supplying cooling to various systems associated with the JET fusion experiment.” To help, Micronics’ Ultraflo 3000 was chosen because it offered a non-invasive, quick and reliable flow


measurement solution. Benefits include an easy to follow menu, simple set up, and it proved to be a cost-effective alternative to a traditional in-line meter installation. In addition, no installation drain down or pipe cutting was required and dry servicing is possible.

Condition monitoring systems from Schaeffler have been installed in the engine rooms of the AutoStar and AutoSun ships operated by United European Car Carriers (UECC). On each ship, a single, eight-channel FAG


DTECT X1s system, mounted in a protective enclosure, is monitoring four vibration points (two on the gearbox input shaft and two on the output shaft) on each of the two main engine gearboxes. A panel PC displays the vibration data from each gearbox. The systems are connected to the ship’s V-SAT communications system. Schaeffler is providing UECC with ongoing


exception-based remote monitoring services via this V-SAT link. This service not only provides UECC with an early warning system for any

potential gearbox failures, but also generates useful diagnostics and trend information that UECC can give to class inspectors (e.g. Lloyds Register) during routine ship audit inspections. The gearbox diagnostics reports eliminate the need for time consuming, one-off gearbox inspections, explains the company. Bob Hargreaves, managing director of


HargreavesMarine, Schaeffler UK’s partner for the marine industry, commented: “We’ve adopted an exception-based monitoring strategy, whereby every 12 hours, vibration data from the gearbox monitoring systems is sent ashore to us via satellite link and cloud server. We can look at the vibration frequency of the bearings inside the gearbox in order to detect any deviations from


the norm. We can therefore monitor the health of the gearboxes and notify the ships’ engineers if any remedial action is necessary.”
