APCI-3300 – DAQ PCI Card – Pressure measurement

The PCI pressure measurement card APCI-3300 has 8/4 differential inputs for for strain gauges8/4 onboard voltage sources for the connected pressure sensors, 4 digital inputs, 24 V, and 3 digital open collector outputs. The card is suited for the industrial pressure measurement in the harsh industrial environment. Acquisition can be triggered through software, timer or external event.



  • PCI 3.3 V or 5 V

Analog inputs:

  • 18-bit resolution, unipolar, 16-bit accuracy
  • 8 or 4 differential inputs for strain gauges
  • Voltage range from 0 to + 1.25 V
  • 4 or 8 voltage sources for the connected pressure sensors
  • Output voltage for the voltage sources 5 V, 30 mA
  • Gain and offset calibration
  • Calculation of the pressure value through software
  • Programmable gain
  • 16-bit accuracy with a sample rate of 20, 40, 80 or 160 Hz

Analog acquisition:

  • Acquisition triggered through software, timer, external event
  • Trigger functions:
    – Software trigger or
    – External trigger: the analog acquisition (single or sequence) is started through signal switching from 0 V to 24 V at the digital input 0.
  • Connection of linear sensors (Wheatstone Bridge)


  • 4 digital inputs, 24 V and 3 digital outputs, open collector, optically isolated

Safety features

  • Optical isolation 1000 V
  • Creeping distance IEC 61010-1
  • Protection against overvoltage (±30 V) and high-frequency EMI


Calibration tool (Option CAL3120): Do the fine adjustment fast and reliably and save the generated calibration report file. All you need is a highly precise calibration source and a precise digital multimeter (not included in the delivery content)

Measurement device for clutch discs

A plunger gets down until it reaches the clutch disc. The plunger is turned and thereby force and distance are measured.
