Sensor: Dual-Axis Accelerometers

Some of our most exciting sensors are the Vertex line of accelerometers. The Dual-Axis accelerometers are particularly exciting as great for measuring gestural energy in two directions. Our specialized scaling provides an additional "Tilt Optimized" version that provides two axes of tilt data.

Applications include mounting on instruments, mechanical installations, and other surfaces that may be in some form of motion. As always we have fully conditioned and scaled the output signal to the industry standard voltage range of 0.25-4.75 Volts, perfect for the Teabox.

As with all of our sensors, we have taken care to make certain that this sensor is of highest quality.
