Explosive environments: fundamentals of area classification

A guide for plant management and technical staff on how to conduct an area classification, the process whereby the degree of exposure to explosive atmospheres for a plant area is determined. Area classification (called “classification of hazardous locations” in our mines) is the process whereby the degree of exposure to explosive atmospheres for a plant […]

Dynamic flow measurement system for tanker offloading

  Shipping across Egypt instead of through the Suez canal is cheaper, quicker, and more flexible, but it requires custody transfer metering that is accurate with billing acceptable to owner, customer, and Sumed – the transport company. Ain Sukha offloading terminal for very large crude carriers (VLCC) is particularly problematic for dynamic flow measurement due […]

Protecting linear positioning sensors in harsh environments

  All industrial manufacturing, ranging from refining raw materials to plastic bottles to aerospace vehicles, is driven by a balance of economics and performance. Companies that can increase the performance of their operations and products without unrealistic costs can create a true value differentiation from their competitors and drive innovation in the industry. One of […]

Measuring the transverse sensitivity of vibration transducers

  The National Metrology Institute of South Africa (NMISA) has implemented a system to measure the transverse sensitivity of vibration transducers. As a mechanical device, the principle sensing axis of an accelerometer is not 100% perpendicular to the mounting axis. This gives rise to the effect that the accelerometer will produce an electrical output even […]
