Where do we get the guidelines to ensure the maintenance programmes we design are effective? This ‘tech byte’ from IRISS provides further details.
In some applications, the distance between a load cell or force transducer and the measuring instrument may be considerable, possibly hundreds of metres. The voltage drop along the connecting cable of a four-wire connection system and its associated temperature coefficient of resistance may contribute significantly to the overall system error. This additional error can be eliminated by the use of the six-wire connection technique where the voltage is sensed locally to the load cell ...
In the context of motion tracking and virtual reality, there is a strong need for sensors to monitor the motion of a moving object. A six-DoF (degrees of freedom) AC magnetic field detection system is presented in this paper.
Today’s machine builders confront a new era of risks, as globalisation increases competition and the internet rapidly disseminates information about products and markets. The highest priority for designers of performance-driven machinery is to reduce the various risks confronted across the machine design, development and maintenance lifecycle.
The measurement of moisture in natural gas is an important parameter for the processing, storage and transportation of natural gas globally. Natural gas is dehydrated prior to introduction into the pipeline and distribution network. However, attempts to reduce dehydration result in a reduction in ‘gas quality’. Consequently, to strike the right balance, it is important that the water component of natural gas is measured precisely and reliably.
In order to maximise the performance of sensors, attention should be paid to the selection of the humble cable that connects the sensor with its instrumentation. As this article in the ‘Mike Might Know’ series from Sherborne Sensors explains, sensors — particularly those based upon strain gauges — have very low levels of output often in the micro-volt region. Noise pick-up must be minimised to ensure accurate results.
A new tip-tilt mechanism based on low-voltage piezoelectric actuators has been designed by Cedrat Technologies to answer the high level of stability required for the Earthcare satellite. The Beam Steering Assembly aims to deviate a pulsed high-energy UV laser beam to compensate for misalignment between the emission and reception paths of ATLID with a very high stability and resolution.
There exists a dangerous misconception regarding the ‘arc rating’ of infrared (IR) windows or viewing panes. Many reliability and maintenance professionals are under the impression that an IR window will protect them in the event of an arc blast; still others are under the impression that installing IR windows will turn non-arc-rated switchgear or electrical equipment into ‘arc-rated’ cabinets. Neither are the case and both misconceptions must be corrected because they present very ...
