Designers who understand and can take advantage of the differences between fluid power and traditional electromechanical power can build machines that produce higher quality output with lower lifecycle costs. This white paper suggests that care must be taken, however, in selecting and sizing the hydraulic system elements and in tuning the motion controller for optimal performance.
Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.
This application note from Delta Controls outlines selection and installation criteria for using admittance probes to monitor the level of powders, liquids and other materials. Dielectric constants of more than 200 materials are included.
Processors have long recognized the importance of tank and reactor cleaning to product quality. This NLB white paper discusses cleaning methods and the significant implications your choice can have on productivity, safety and profitability.
Specifying a hygienic bulk solids feeder is not a simple task. The wide variety of requirements needed
for specific applications are similar in scope to explosion proof environmental requirement variations.
A bearing isolator is a non-contact, non-wearing, permanent bearing protection device. It has a rotor and a stator, and the two are unitized, so that they dont separate from one another while in use. Typically, the rotor turns with a rotating shaft, while the stator is pressed into a bearing housing. The two components interact to keep contamination out of the bearing enclosure and the lubricant in.
Plant security is a key priority at many plants. This 10-page paper provides background what the methodology for a plant vulnerability analysis involves. It covers topics such as how to get started, available tools, and risk assessment.
This 17-page whitepaper discusses the application of two popular methods of determining SIL requirements risk graph methods and layer of protection analysis (LOPA) to process industry installations.
This eight-page PDF whitepaper discusses the importance of transmitter selection for centrifugal compressors. Appropriate selection is especially important in anti-surge and throughput control applications.
