  • Voltage Portals Improve Non-Contact Voltage Detectors
    A voltage portal also makes a perfect voltage panel label. Perhaps it is even a 'better label' because it serves two. purposes: a test point and a label. Imagine if every voltage. source entering an enclosure was wired to a voltage portal?. Workers would see and be able to test every voltage source
  • No contact means no headaches in position transducing
    for the noncontacting potentiometer shows the coupling capacitance , and the stray ground capacitance, , are then summed by the integrating amplifier. The amplifier output voltage, , is proportional to the position of the probe. Noncontacting potentiometers typically are more linear than contacting types
  • Selection Guide to Clamp-On Current Probes
    Clamp-on current probes are designed to extend the current measuring capabilities of DNNs, power instruments, oscilloscopes, hand-held scopes, recorders or loggers and other diverse instruments. The probe is "clamped" around the current carrying conductor to perform non-contact current measurements
  • Sensor Sense: Resistive Touchscreens
    , the cover sheet deforms forcing the two coatings into contact. A touchscreen controller links the touchscreen to the computer. The controller first imposes an electrical voltage horizontally across the resistive coating of the glass creating a voltage drop across the surface. The conductive coating
  • Ground Isolation in Video Transmission
    In coax video transmission systems the shield of the coax cable is usually connected to ground. It may very well turn out that a voltage difference at the power line frequency may exist between the ground at the transmitting location and the ground at the receiving end. The 60 Hz current through
  • Medical Device Link .
    A component enables contact-free transmission of analogue signals from a rotating or moving module to one that is stationary. The Inpud-A module comprises a 24-V-dc transmitter with a maximum of four interfaces.These can be operated as voltage outputs or, for long transmission distances
  • Clamp-On Current Monitors Achieve Wide Bandwidth (.pdf)
    Viewing and measurement of electric current is so important that a variety of devices and methods have been developed and refined over the years. In its simplest form, current may be measured by placing a resistor in the circuit under teat, and then measuring the resulting voltage developed
  • Shaft Displacement Measurement Using A PROTOR System
    Shaft displacement is an important vibration measurement for rotating machines. Shaft displacement is usually monitored by non-contact shaft displacement probes such as eddy-current probes. These probes produce a voltage proportional to the distance of the shaft surface relative to the tip
