The piezoresistive sensor element is made of monolithic resistors. These resistors are attached to carrier-elements and are electrically connected in a Wheatstone bridge. The electrical signal changes proportional to the vibration. Description The model ASC 66C1 is a uniaxial accelerometer based on piezoresistive technology. The ASC 66C1 is small and compact accelerometer which meet the specifications of SAE J211. The housing is a flat design made of hard anodised aluminium. Due to low mass, the model is ideal for testing on light-weight structures. The sensing element has integrated overload stops and therefore the silicon chip is highly shock resistant. The ASC 66C1 has an excellent non-linearity over a wide frequency response. Electrically the units features a Wheatstone bridge configuration. The model ASC 66C1 can be obtained with all common sensor ID modules. A very high flexible and rugged cable provides a simple mounting. The model ASC 66C1 is factory calibrated and is equipped with 6 meter cable as a standard.
