The Endevco Model 7293A Microtron accelerometer family uses unique variable capacitance microsensors and incorporates special filtering and shielding for EMI and RFI exposure.
Designed for measurement of steady-state or low-frequency, low-level accelerations, the Model 7293A is ideal for aerospace and factory environments where EMI and RFI are a particular concern.
The Model 7293A's anisotropically etched silicon microsensors can withstand high shock (up to 10,000g) and acceleration loads.
The use of gas damping on the sensors results in very small thermally induced changes in frequency response.
The Model 7293A can operate from 9.5c to 18.0V DC.
It provides a high-level low-impedance +2V differential output, which is decoupled at a DC bias of approximately 3.6V.
Endevco's Model 136 three-channel system or Oasis 2000 computer-controlled system are recommended as signal conditioner and power supply.
