The light weight, Type 8730A... accelerometer series uses Kistler’s uniquely designed K-Shear quartz sensing element. Operating in the shear mode with precisely cut quartz plates, allows the accelerometers to exhibit ultra low sensitivity to thermal transients, base strain and transverse motion. Housed in a hermetically sealed titanium case, the quartz sensing elements afford excellent long-term stability that ensures repeatable and accurate measurements.
The standard Type 8730A... and the low temperature 8730A500M8 accelerometer weighs only 1,9 grams while the M1 version which is slightly larger and "off-ground" weighs 2,5 grams. Internal microelectronic Piezotron ® signal conditioning circuit converts the charge developed in the quartz element as a result of the accelerometer being subjected to a vibration, into a useable high level voltage signal at a low impedance output. The low impedance output provides high immunity to noise and insensitivity to cable motion. Kistler’s design allows the use of rugged, low cost coaxial cable between the accelerometer and power/readout equipment. Where minimum cable and connector weight are desirable, Type 1761B... general purpose cable is recommended
