| TY-BBAS-2 |
|
TY-BBAS-2 Accelerometer using the Electro-mechanical integration design, Force-balanced and Electronic-feedback technique features good linear, broad frequency band and large dynamic range. It as well as its relative circuits which includes displacement-transduction Electronic-feedback circuit, Calibration circuit, balanced output driving circuit and isolated DC/DC transducer is installed in an airtight Aluminium case with the dimensions of 120mm × 120mm × 65mm. TY-BBAS-2 has got specially-designed level regulation bolts as well as a level bubble to be used to regulate the horizontal orientation, and a centered mount hole through which only one bolt can fix up itself, which makes the installation very simple and reliable. It is also very convenient to realize the testing and calibration towards the accelerometer from the data recorder in the distance.
