Piezoresistive MEMS Technology
Features
 Range: 500g, 1000g and 2000g
 Small Size
 Light Weight
 DC Response
 ±5000g Shock Resistance
 Gas Damped

The accelerometers are based on an advanced piezoresistive MEMS technology and can be
used in a low frequency response up from 0Hz. 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.

 TEDS Module
 Shunt Resistor
 Equipment Exchange (EQX)

The model ASC 74C1 is a triaxial accelerometer based on piezoresistive technology.
Each axis is working independently as a 4-wire system.

Applications
 Automotive Crash Testing
 Shock Testing

The models ASC 74C1 and ASC 74C1A are small and compact accelerometers which meet
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.

Description

The model ASC 74C1A is a signal amplified triaxial accelerometer based on piezoresistive
technology. It is specially designed for crash test applications. Its ±2 volt differential
output is dc coupled. Each sensing element of the sensor is separately replaceable.

The models can be obtained with all common sensor ID modules. A very high flexible cable
provides a simple mounting. The models ASC 74C1 and ASC 74C1A are equipped as
standard with 6 meter of rugged Polyurethane cable.
