  • 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
  • Load Switching and Contact Protection (.pdf)
    within the glass capsule. To Contact damage and even sticking will occur depend-. receive the maximum life for a given load some precau-. ing up the total capacitance, voltage present and series. tions may be necessary. resistance. Because a Reed Switch is a mechanical device and has Tungsten filament
  • Non-contact Temperature Measurement and Control (.pdf)
    sophisticated by using. automatic (closed loop) control systems. The temperature of the moving material is. continuously measured with a non-contact radiation thermometer known as a radiation. pyrometer, and the reading compared with a stabilized voltage representing the desired. temperature, or set point
  • Contact Resistance Analysis for Press Fit Applications
    that contact resistance testing should be carried out using the mil ivolt level. method as specified in IEC 60512-2-1. In addition, care must be taken regarding the resolution of the. micro-voltmeter as well as corrections for thermo-electrical voltage. The measuring points should be. made as close
  • Large Surface Area Contact Mating System (.pdf)
    contact resistance provides energy savings and minimized voltage drop across. the contact. ➢ “Closed Entry” design prevents damage to female contacts and will not allow. POSITRONIC INDUSTRIES, INC. misaligned or bent contacts to enter. 423 N Campbell Avenue. ➢ Precision machined from solid, high
  • Non-Contact Thickness Measurement of Semiconductor Wafers
    removal rates are within customer specifications. The thickness measurement device must not only be capable of producing a highly accurate reading, it must do so without contacting the wafer surface. Capacitance based measurement probes have long been employed as a means of non-contact measurement
