TDA series three-direction accelerometers have currently two models
of accelerometers, TDA-23 and TDA-33M. TDA-23 is electronic accelerometer, and TDA-33M is mechanical one.
They are small size accelerometers with low power consumption. They
are easy to be adjusted and can work stably for a long time. They
have a sealed package, so can work under water. TDA-23 three-direction electronic accelerometer uses the latest
integrated accelerometer chip, to meet the needs of a macroseism
measurement for dynamic range. It features small volume, low power
consumption (< 0.5W), zero fine toning, continuous, stable and
reliable operation. Picture: The following picture are the photo of TDA-23 three-direction
electronic accelerometer that build in a seismic station ( its
formal size:110×95×45 mm) and the photo of TDA-33 three-direction
mechanical accelerometer.
