• Introduction to Current Source Power Units
  . The source load RS is remote, i.e., it is located in the power unit and not within the sensor housing. It is apparent upon examination of this circuit that the power to the sensor amplifier and the signal from the sensor amplifier are carried over the same two wire conductor. This fact makes possible...

• Introduction to LIVM Accelerometers
  amplifier. The quiescent DC bias level (turn-on voltage), at the power input to the accelerometer, may fall within the range of +8 to +12 Volts DC, depending upon the specifications of the particular model. The actual measured value is reported on the calibration certificate supplied with each...
• New Roles For Ceramic Parts
  nozzle. The insert has higher density and strength, and lower porosity than the surrounding material. This improves dimensional stability and resistance to erosion and corrosion. These automotive knock sensors contain a small piezo element which, when combined with an FET-amplifier, helps adjust timing...
• Sensor Sense: Piezoelectric Force Sensors
  with internal amplifiers do require external power to operate the amp. This cross-section diagram of a Series 208 Quartz Force Sensor from PCB Piezotronics Inc. of Depew, N.Y., shows the basic assembly of a piezoelectric sensor. Want to use this article?

• Interfacing Pressure Sensors to Microchip's Analog Peripherals
  Pressure measurement devices can be classified into two groups: those where pressure is the only source of power and those that require electrical excitation. The mechanical style devices that are only excited by pressure, such as bellows, diaphragms, bourdons, tubes or manometers, are usually...

• Putting together a high-tech garage band
  to make some compromises. The pickups, for example, are piezoelectric rather than magnetic. Each generates an ac time-variant signal that represents the changing tension in the string being struck. They use piezo pickups for their wide dynamic range and bandwidth to ensure they get all...
