The Endevco Model 7293A Microtron accelerometer family uses unique variable capacitance microsensors and incorporates special filtering and shielding for EMI and RFI exposure.
It is available in ranges of 2, 10, 30 and 100g full scale and provides a high level, low-impedance full scale output of +/-1.75V peak.
A reference voltage output is provided to allow either a single-ended or pseudodifferential output.
A temperature output is available for applications where accurate temperature corrected acceleration data is required.
The frequency response is controlled by the near-critically damped sensor.
The use of gas damping results in very small thermally induced changes of frequency response.
Warm-up time to within 1% of final output value is less than 10ms.
The 7594 operates from 5V DC.
The ceramic base, hermetically sealed package is designed for adhesive mounting.
The electrical connections being made via solderable or wire bondable pads.
Hermetic sealing ensures long life and stability.
As with all 7290 series accelerometers, the 7594 is extremely rugged and capable of withstanding high shock levels without damage or changes to its characteristics.
The 7594 is 15.9 x 15.9 x 3.8mm and weighs 1.6g.
