Time-of-arrival, ICP® Micro-pressure Sensors
High sensitivity micro-pressure sensors are well suited for short wavelength acoustic and shock wave measurements associated with high-frequency projectile detection systems. Incorporating a 1mm diameter sensing element and integral microelectronics in a 3mm housing, these sensors have very high sensitivity and microsecond response capable of identifying the bow and stern wave from a passing projectile. An internal 8 kHz high-pass filter eliminates low-frequency inputs. Series 132 Microsensors are available in five different physical configurations to accommodate a wide range of application requirements.
Model 132A30 Microsensors all have a sensitivity of 100 mV/psi and come in a variety of external configurations to suit your specific application. |
 Highlights
- Shock wave time-of-arrival ICP® microsensors
- 50 psi (344 kPa) range
- Rise time <3 µsec
- Resonant frequency >1M Hz
- Diaphragm diameter of 0.124 in (3.15 mm)

| Series 134 |
Tourmaline Pressure Bar
This unique non-resonant sensor is designed for instantaneous, reflected (face-on) shock wave pressure measurements in dry environments. A shock wave pressure impacting the very thin tourmaline crystal which operates into a silver alloyed “pressure bar”, eliminates sensor structure response. The sensor has a 0.2-microsecond rise time. The sensor diaphragm end is coated with a conductive silver epoxy. |
 Highlights
- Designed for reflected shock wave pressure measurement
- Unique non-resonating design, Tourmaline sensing element
- Pressure ranges from 1000 to 20k psi
(6894 to 137,900 kPa)
- Rise time < 0.2 µsec

| Series 137 |
ICP® Free-field Blast Pressure “Pencil” Probe
Series 137 incorporates acceleration-compensated quartz elements and integral microelectronics for long cable driving, improved stability and low thermal sensitivity. |
Highlights
- ICP® free-field blast pencil probes
- Ranges from 50 to 5000 psi (344 to 34,475 kPa)
- Rise time <4 µsec
- Resonant frequency >500k Hz

| Series 138 |
ICP® Tourmaline Underwater Blast Sensor
Series 138 Sensors measure shock wave pressures associated with underwater explosion testing. The sensors are structured with a volumetrically sensitive tourmaline crystal, suspended and sealed in an insulating, oil-filled vinyl tube. They have integral microelectronics. These underwater shock wave sensors provide a clean, non-resonant, high-voltage output through long cables in adverse underwater environments. They can be supplied with a sealed cable of appropriate length, ready to operate. Two physical configurations are available. |
Highlights
- ICP® underwater blast explosion pressure probes
- Ranges from 1000 to 50k psi (6894 to 344,740 kPa)
- Rise time <1.5 µsec
- Resonant frequency >1M Hz
