2 axis accelerometer

2 AXIS ACCELEROMETER

MICRO

Accelerometers are available to measure up to three axes in a single, robust package. The sensing element is a micro-machined MEMS device. An internal amplifier provides an output between 0 and 5 volts. The unit contains a ±35g sensing element which is scaled to ±5g. This element can be replaced with a ±10g sensing element scaled to suit the g range of interest and application.
