View Options

Details

Features
  • PCI interface to the 32-bit data bus, 3.3 V or 5 V
  • Acquisition of 8 or 16 inductive transducers (half-bridge, LVDT)
  • 16-bit resolution
  • Sampling rate depending on the transducer: APCI-3701-8/-16: from 2 to 20 kHz
  • Measuring frequency programmable through software: Standard version APCI-3701-8/-16: from 2 to 20 kHz (50 kHz on request)
  • Conversion triggered through software, digital input or timer
  • End of conversion through software and/or interrupt
  • PCI-DMA access
  • Onboard FIFO
  • Sequence RAM
  • 16 digital inputs and outputs, optically isolated, 24 V
  • Connection of the transducer through an external box PX 3701-8 or -16. The box type depends on the transducer, please order separately.
  • Software operation
  • Automatic setting of the input levels (gain and offset) acc. to the transducer sensitivity
  • Tool for the individual databased calibration of the transducers
  • Database for connecting/calibrating a large range of industry-standard transducers (APCI-3701-8, or -16): Solartron; Tesa; Marposs; Schlumberger; Peter & Hirt; Mahr; RDP; Schaevitz; SMPR Controle. Further transducers like for example Horst Knaebel can be calibrated on request.
