ISPK30I - 300 kHz Intrinsically Safe AE Sensor with Low-Power Integral Preamp

The ISPK30I is a narrow band sensor featuring 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 26dB which can drive up to 200 meters of cable. The sensor has a resonance frequency around 300 kHz. 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 ISPK30I features an anodized aluminum cavity with an SMA connector. The preamplifier features an auto sensor testing (Tone Burst AST) feature through which the sensor can be used both as pulser and receiver.
