ISPK15I - 150 kHz Intrinsically Safe AE Sensor with Low-Power Integral Preamp

ISPK15I - 150 kHz Intrinsically Safe AE Sensor with Low-Power Integral Preamp

ISPK15I is a medium frequency, resonant Acoustic Emission sensor with an integral ultra low noise and low power preamplifier. It is designed to meet the intrinsic safety (IS) standards (when used with our 1281-IS AE interface) and IP65 environmental requirements. The bandpass filtered preamplifier has a gain of 26 dB and can drive up to 200 meters of cable. This sensor represents an improvement in both noise and power consumption. With noise level below 3 µV and power consumption as little as 25 mW, the sensor is ideal for use with battery powered portable equipment. The ISPK15I features an anodized aluminum cavity with an SMA connector exiting to the side. The preamplifier features an auto sensor testing (Tone Burst AST) feature through which the sensor can be used both as pulser and receiver.
