Accelerometers А-18T
Accelerometers A-18T are designed for measurement of linear accelerations in inertial navigation systems, AHRS and control systems of aerial, naval and land vehicles. A-18T is modification of A-18 with improved technical and operational characteristics.
Accelerometers are sensors with sensing element made of monocrystal silicon and built-in feed-back electronics. The input signal is analogous.
