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)

Specification Notes

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