The new model BST 963 is a small triaxial accelerometer based on IEPE Shear design with a very good Signal-to-Noise Ratio. The accelerometers are designed for relatively low amplitudes. The housing is mountable with a screw in the centre and bolts on two other sides. The sensor has 2m very high rugged and flexible cable, this makes it easy to connect the sensor on am constant current source or data acquisition systems. It operates between 2 and 20 mA constant current. The housing is Aluminium.
