Capacitive Accelerometers test automotive components.

Press Release Summary:

ACC-B Series accelerometers use gas-damped, spring-mass system as part of their primary converter; integrated signal conditioner transforms capacitive response into analog DC output signal. Model B1 has capacity of +/-3g; Model B2 has capacity of +/-10g; and Model B3 has capacity of +/-50g. All units are shockproof to 10,000 g and have hermetically sealed housing, true dc response, and integrated sensor electronics.

Capacitive Accelerometer Introduced For Automotive Acceleration Measurements

FARMINGTON HILLS, Mich., March 4, 2002 - CAESAR Data Systems has launched a new capacitive accelerometer for the automotive component testing market.

The prime market for the ACC-B Series capacitive accelerometer is automotive. Road-load testing, product shakers, fatigue testing, engine vibration tests - almost all forms of test lab work for cars, trucks, and off-highway vehicles -- require some form of acceleration measurement. But, since it can measure the acceleration, vibration and inclination of any object, the ACC-B series has myriad measurement applications - from robot arms to elevators, from product shipping research to aircraft testing.

The new capacitive accelerometer, a design development of CAESAR Data Systems, uses a gas-damped spring-mass system as part of its primary converter; an integrated signal conditioner transforms the capacitive response into an analog DC output signal. Very low temperature drift and high long-term stability make it an economical choice for acceleration measurements.

A real key aspect of this product is that it uses a capacitive-type sensor rather than piezo. It produces a higher level output signal for increased noise immunity; this means it doesn't need to be amplified or filtered. And it's available in three capacities, making it easy to fit the application.

Model Bl's range is (+/-) 3g; Model B2's is (+/-)10g; and Model B3's is (+/-) 50g

Capabilities include:
* Shock-proof to 10,000g;
* High long-term stability;
* Hermetically sealed housing;
* True dc response;
* Low temperature drift;
* No signal hysteresis;
* Integrated sensor electronics;
* Low power consumption; and
* Signal conditioning modules with three measuring ranges per

CAESAR Data Systems was founded in 1986 by a group of four engineers experienced in the field of data acquisition and analysis technology. The company today is a leading supplier of measurement systems for mobile vehicle testing.
