  • Measuring liquid levels with LVDTs
    LVDTs sometimes work better than pressure sensors for gauging tank volumes. A common way of measuring the level of liquid in a tank places a low-pressure sensor at the bottom. The pressure readout is the product of the liquid column height times the density of the liquid. As long as liquid density
  • Liquid Level/Interface Monitoring in Flocculant/Sludge Control (.pdf)
    to efficient water. treatment. The level/interface instruments that support the. process liquid measurements must be capable of distinguishing. between liquids with varying properties in order to detect the. levels where the different liquids interface in the pond or tank. With this knowledge
  • Expansion or Shrinkage of Liquid Silicone Rubber
    image on the left below for an example of a pvT diagram). The measurement is defined in ISO 17744. With increasing temperatures, Liquid Silicone Rubber (LSR) expands. When pressure is applied, the overall specific volume shows a lower value, which means the density is higher. In addition
  • Measuring Transition Points in Liquids with Different Densities with Sensortechnics' Capacitive CLC and CLW Level Sensors
    measurement of. liquid level and can be easily mounted to the. outside of a container or vessel. The CLC. series measures continuously whereas the. CLW devices detect point levels. Further more, due to their sensitivity and. teaching possibilities these sensors can be. used to determine transition points
  • Liquid cooled LED arrays as bright as 30 headlights
    . A joint project sponsored by VDI/VDE-IT Bavaria faced these challenges and developed compact LED modules with a high packing density and output. The Electronic Applications Division at CeramTec GmbH supplied innovative aluminium nitride (AlN) liquid-cooled heat-sinks; the Fraunhofer IZM institute
