Force Balanced Accelerometer
PA-23, PA-23BH, S-230 - Geotech Instruments, llc (Geotech)
The Geotech Model S-230 is a high resolution, 1-component, force balanced accelerometer capable of meeting the noise and stability requirements of the most demanding seismic studies. It features a very wide frequency response (DC to 90 Hz) and an internal calibration coil. Three S-230 accelerometers are packaged as a borehole 3-component unit (Model PA-23BH) and as a surface 3-component unit (Model PA-23). PA-23BH can be submerged up to 100 m depth.
