Model SA-4
The SA-4 Low Power Acoustic Pressure Sensor is a perfect sensor for complimenting the monitoring for seismic systems. Especially designed for Volcanic Monitoring, the SA-4 monitors low frequency sound waves and can be used for many other seismic applications.
It is a perfect companion with eentec’s SP or EP line of seismometers and the R-1 rotational seismometer.
The SA-4 Acoustic Pressure Sensor monitors the sound band flat from 1Hz to 700Hz. It comes standard with four inlets. The unit is fully calibrated, with a dynamic range of 125dB, a sensitivity of 4mV/Pa, and a full scale of +/-100Pa. The full-scale output is +/-5V. It operates off of 12VDC, normally supplied by the recorder or telemetry station.
The SA-4 is very rugged. Housed in a PVC enclosure it is waterproof, corrosion proof, and operates over a wide temperature range.
It is easy to install and requires no specialized procedures. The unit comes standard with a 3m cable with flying leads to connect to the recorders sensor input.
Options available are a higher frequency response to 10,000Hz , or a lower option to 4 seconds, a higher full scale output to +/-10V, and additional input ports.
