Type 4624AK data sheet - .PDF file.

Kistler’s new single-channel measuring amplifier for piezoresistive pressure sensors is suitable for a range of applications using high-accuracy measurements with digitally compensated sensors. The Type 4624AK amplifier is designed to interface with Kistler PiezoSmart sensor identification and is said to be ideal for use with digitally compensated sensors, allowing the characteristic values to be automatically read out from the electronic sensor data sheet (TEDS).

The new amplifier is especially suitable for applications using a small number of sensors where a multi-channel amplifier would be uneconomical or difficult to accommodate, as are often encountered in motor vehicle and aerospace testing. The amplifier may also be used with pressure sensors that are not equipped with sensor identification.

It is suitable for signal processing for most common piezoresistive pressure sensors and the easy-to-use single channel measuring system is particularly recommended where maximum precision is required such as on-board measurement in motor vehicles or for demanding measurement tasks in testing laboratories.

Key features and benefits

  • With the characteristic values of the sensor (sensitivity, zero point) being entered manually via an Ethernet connection and a web browser, saved on non-volatile memory, the sensor data is protected in the event of power loss.
  • The measuring chain is ready for use once automatic or manual amplifier configuration has been completed.
  • Correction of the zero point of the sensor (e.g. for adjusting to barometric pressure) may be set using pushbuttons on the housing of the amplifier or via the Ethernet on the web browser.
