Datasheet

Quartz, free-field, ICP® blast pressure pencil probe, 50 psi, 100 mV/psi, 4-pin connector, with two outputs for T.O.A

This is a 2-sensor pencil probe that provides time of arrival from which shock speed may be calculated and the pressure time wave form for total impulse measurement, all in one sensor.

  • Measurement Range: 50 psi (345 kPa)
  • Sensitivity: (±15%) 100 mV/psi (14.5 mV/kPa)
  • Resonant Frequency: >=400 kHz
  • Electrical Connector: 4-Pin
  • Weight: 16.1 oz (456 gm)

Product Notes
[1] Zero-based, least-squares, straight line method.
[2] For +10 volt output, minimum 26 VDC supply voltage required. Negative 10 volt output may be limited by output bias.
[3] Two identically spec'd elements spaced 10cm apart - see drawing #65310 for details. Individual calibration certs supplied for each channel.
[4] Typical.
[5] See PCB Declaration of Conformance PS023 for details.
