  • Coatings Corner: What is an EMI Shielding Window?
    An EMI shielding window is an optically transparent, electrically conductive barrier that significantly reduces the amount of electro-magnetic radiation that might pass through it. These shielding windows are commonly surrounded by non-transparent barriers that are more effective EMI shields
  • What is a Water to Air Heat Exchanger?
    A water-to-air heat exchanger uses a steady supply of water to dissipate heat within an electrical enclosure or equipment cabinet. In this type of cooling system, water is circulated through a finned-tube coil. As heated air from the enclosure passes through the coil, the water absorbs the heat
  • Resistor Stability and Calculating Drift
    All resistors share one property: stresses, whether mechanical or thermal, can cause a resistor to change its electrical parameters. Temperature and power dissipation will cause this stress in circuits. When current passes through a resistor it generates heat, and the thermal reaction causes
  • White Paper: The Importance of Isolation
    Electric current refers to the conceptual flow of atomic particles or electrons through wires and electrical devices. Conductive materials like metal and water allow electric current to easily pass through them. The force that drives electric current to flow through a conductive medium is potential
  • History and Properties of Thermoelectric Devices
    In 1834 Jean Peltier discovered that when electrical current passes through a closed circuit made up of two dissimilar metals, heat energy is absorbed at one dissimilar metal junction and discharged at the other junction. This discovery is the basis for all thermoelectric devices, and is quantified
  • Inclinometer used in nuclear industry
    Nuclear energy into electrical energy process need to pass all kinds of complicated change program, through the various reaction equipment, while some need to flip, in turn process are also full automation, but some large scale equipment can't flip over certain Angle range, otherwise you will fall
  • Application Note: What is a Transparent Heater Window?
    through the coating. The electrical resistance of the coating creates heat energy which heats the glass, which then radiates heat.
  • What is an Air to Air Heat Exchanger?
    An air-to-air heat exchanger uses a specialized heat transfer element and two separate airflows to remove heat from an electrical enclosure. In this closed-loop enclosure cooling system, the air surrounding components is passed through either a coil with refrigerant or a convoluted metal foil
  • When Wire Feedthroughs Make Sense
    Engineers who work with pressure and vacuum chambers usually reach for off-the-shelf sealed bulkhead connectors when they need to pass power and signal wires through the chamber wall. And while these connectors may seem like the best or only way to breach the chamber walls, they can actually drive
  • How Big Are Your Droplets? Find Out Using Laser Doppler Anemometry
    As two properly configured laser beams intersect,. the light beams set up an interference pattern. As a. droplet passes through this interference pattern, it. scatters the light from the pattern in a burst of. reflected light. The properties of the scattered light. depend on the droplet size
  • Temperature Rise and Insulation Class Relationship
    current passes through a wire, losses, primarily attributed to the resistance in the wire, will generate heat. The amount of heat generated will be dependent on the resistance and the amount of current which is being passed. The transfer of this heat into the surrounding structures must be dissipated
  • Motion Control and Encoder Technology: A Tutorial
    diaphragm or mask (4), which splits the light into a second channel 90° out of phase, an output style called quadrature. The two light channels (A and B), pass through the tempered glass, polycarbonate or metal pulse disc (2) onto the photodiode array (5).
  • Powerstar Shipboard Power & Isolation Transformers (.pdf)
    . Since seawater is highly conductive, the electricity will pass through him to get to ground. He gets zapped. So ships use a 3 phase ungrounded ? Delta design generator. For battle field situations with this design, they also can tolerate a single phase- to-hull short and continue operating.
  • Derating For Real World Conditions
    controls when incorporated into an electrical circuit. By altering the. sensitivity of the bimetallic element, a designer can make the device either more. or less sensitive to current flowing through the circuit and ambient temperatures. surrounding the device. The sensitivity of the bimetal is actually
  • How a Vortex Flow Meter Works
    to measure the natural frequency produced during vortex shedding include: Piezoelectric crystals and ceramics - These materials produce an electrical charge in response to an applied mechanical stress. As vortices pass the sensor, they apply the stress needed for the piezoelectric material to produce
  • A Microfluidic System for Biological Particle Enrichment Using Contactless Dielectrophoresis
    Report. 224 JALA June 2010. electric field, has shown great potential as a method for sample. concentration.5,6 Typically, sample concentration. through DEP involves the placement of an array of interdigitated. electrodes under a microfluidic channel through which. the sample fluid passes
