  • Piezoelectric Measurement System Comparison: Charge Mode vs. Low Impedance Voltage Mode (LIVM)
    proportioned ceramic element. A miniature IC metal oxide silicon field effect transistor (MOSFET) amplifier built into the housing of the sensor, converts the high impedance voltage signal from the quartz element to a much lower output impedance level, so the readout instrument and long cable have little

  • Lightning and Surge Protectors Tutorial
    Lightning and surge protectors are devices whose purpose is to eliminate transients (spikes) through a conductor (typically a cable) which are induced by nearby lightning activity. They are used to prevent damage to valuable electronic equipment from these high-voltage surges and spikes. Lightning
  • Keeping coax safe
    Special protectors dissipate potentially dangerous transient currents in coaxial cable. When voltages on the center conductor exceed a specific value, the gas in the gas-discharge tube ionizes to discharge the buildup to ground. Even though the quarter-wave stub is electrically grounded
  • AN-0200 - OC100HG Push-Pull Driver in Pockels Cells Switching Methods
    , the. switches were large, expensive, and could not be placed at a close distance to the Pockels. cell. This resulted in a need for several feet of high voltage coaxial cable between the switch. assembly and the cell. This added cable introduced a significant amount of capacitance to. the assembly
  • Introduction to Piezoelectric Pressure Sensors
    treated coaxial cable. It is important to use coaxial cable for this purpose because the input to a charge amplifier is at a very high impedance level and as such, is susceptible to noise pickup if not continuously shielded. The low noise treatment is also important because physical motion of untreated
  • Introduction to Piezoelectric Force Sensors
    Low Impedance Voltage Mode (LIVM) force sensors contain thin piezoelectric crystals which generate analog voltage signals in response to applied dynamic forces. A built in IC chip amplifier converts the high impedance signal generated by the crystals to a low impedance voltage suitable
  • NexTek Coaxial Surge Arrestor Mounting and Grounding Guide
    Coaxial Surge Protectors provide reliable protection from high voltage surged in coaxial lines. These protectors provide long life protection and are critical component for high reliability and uptime. communication systems. The source of surges usually includes lightning, power line faults
