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 76C1 is a triaxial accelerometer based on piezoresistive technology. Each axis is working independently as a 4-wire system. The ASC 76C1 is a small and compact accelerometer which meets the specifications of SAE J211. The housing is a flat design in hard anodised aluminium. The compact cube form facilitates mounting on different sites. Due to their low mass these sensor models are ideal for testing on light-weight structures. The sensing element in the models has integrated overload stops and therefore the silicon chip is highly shock resistant. The sensors have an excellent non-linearity over a wide frequency response. Electrically they are configured as a full Wheatstone bridge. The models can be obtained with all common sensor ID modules. A very high flexible cable provides a simple mounting. The ASC 76C1 is equipped as standard with 6 meter of rugged Polyurethane cable.
