The new generation of seismic sensors from Kinemtrics - EpiSensor series force balanced seismic accelerometers - FBA ES-T sensor is a three-way orthogonal integrated accelerometer suitable for various seismic recording applications. The sensor integrates three EpiSensor force balanced accelerometer modules vertically into a sturdy and compact housing. 

The EpiSensor sensor can select the desired full-scale value within the range of ± 0.25g to ± 4g, and users can choose the appropriate full-scale value for seismic observation and recording near faults or various structures. The bandwidth of the sensor has been increased to DC-200Hz, which enables the study of higher frequency vibrations while maintaining a very important DC response. Users can choose from four output modes: ± 2.5V and ± 10V single ended output, ± 5V and ± 20V differential output. ± 2.5V single ended output is suitable for traditional seismic recording instruments from Keni Company; ± 10V single ended or ± 20V differential output is suitable for Kearney's Makalu 24 bit digital recorder and other popular 24 bit digital recorders in the current market. The EpiSensor series also includes force balanced accelerometers in both single directional (FBA ES-U2) and downhole (FBA ES-SB for shallow holes and FBAAS-DH for deep holes) models.
