• Miniature high sensitivity ICP® probes are used to measure small dynamic hydraulic and pneumatic pressures such as turbulence, noise, sound, cavitation, and pulsations. Capable of measuring high intensity sound pressures from 0.001 psi ({111 dB}air) to 100 psi ({210 dB}air) at any static level from a full vacuum to 2000 psi. Internal acceleration compensation minimizes vibration sensitivity and an internal discharging resistor automatically eliminates static (DC) signal components.

• Model 112A21 is a 50 mV/psi general purpose sensor suitable for most low pressure applications. Model 112A22 has 100 mV/psi sensitivity for greater signal strength
