Columbia Models 947M4, 947M5 and 947M6 Piezoelectric Accelerometers provide an electrical outputs of 0.5 volt per g, 1 volt per g and 2 volts per g respectively over a frequency band of 0.1 Hz to 1500 Hz. It is designed for measurement of the low level, low frequency signals encountered in seismic studies.
The sensors incorporate a 4-pin hermetic connector to permit long-term operation in the most demanding environments. Internal electrical isolation minimizes ground loop problems from noise currents. The Series 947 is designed to operate from DC power sources ranging from 10 to 30 VDC. The low power requirement allows operation from battery sources for portable or remote applications.
