  • How to select a Pressure Switch
    -. ing of the snap-action switch's contacts. Differential pressure switches are slightly dif-. ferent. As Figure 1 shows, there are two pressure. ports, one for the low pressure side and the other for. the high pressure side. The low pressure and high. pressure fluids act on the same sensing element

  • Low Frequency Response and Quasi-Static Behavior of LIVM Sensors
    time constant (TC) of the Low Impedance Voltage Mode (LIVM) sensor and the coupling time constant of AC coupled power units are very important factors when considering the low frequency and the quasi-static response capabilities of an LIVM system. For the time being we will consider only the sensor

  • RF Test Gage R&R Improvement
    Advanced cell phone architectures require high performance multi-throw RF switches. Reliably measuring the very low RF power levels of the third harmonic signal of these switches is a significant challenge. This paper discusses the use of Gage studies to identify and measure the sources
