Page 6: Section 3 - Understanding Your Accelerometer
(picocoulombs charge per g) then you are working with a high impedance sensor. OMEGA's accelerometers are the low impedance type of accelerometer (see Figure 3-1). A low impedance accelerometer is one in which the electronics required to detect the charge generated by the piezoelectric crystal are built right into the case of the sensor. -
Page 7: Low Impedance Micro Circuit
Figure 3-1. Low Impedance Accelerometer LOW IMPEDANCE MICRO CIRCUIT OMEGA has a broad line of micro circuits which yield excellent low impedance output characteristics. These hybrid circuits often include special filtering capabilities and protection schemes. The specific micro chip properties are engineered to create the output characteristics desired. They... -
Page 8: General Characteristics
Isolated accelerometers which from OMEGA are built in variety of configurations eliminate any possibility of ground noise interference. OMEGA Models ACC 101, ACC 102, and ACC are case isolated accelerometers. Figure 3-3. Case Isolated Accelerometer GENERAL CHARACTERISTICS Axis of Sensitivity Most accelerometers are built to be sensitive to motion in one major axis. -
Page 9: Section 4 - Power Requirements
Please refer to the appropriate sales bulletins and operating manuals provided for each OMEGA power supply. Figure 4-1 illustrates how a low impedance accelerometer should be connected to a constant current power supply. This schematic diagram shows the basic components within the accelerometer and power supply. - Page 10 Some data acquisition systems incorporate the power supply portion of the schematic diagram. In these instances, the accelerometer is simply fed into the data acquisition system's input connector which may be labeled "Accelerometer In" or “Integrated Circuit Power" (see Figure 4·2). Figure 4·2.

Page 11: Section 5- Connector Wiring
SECTION 5- CONNECTOR WIRING COAXIAL CONNECTORS Most single axis sensors use a coaxial cable terminating in a coaxial connector. In these cases the center conductor is used for sending power to the accelerometer. The center conductor is also used to transmit the dynamic acceleration signal from the accelerometer. -
Page 12: Section 6 - Cabling Techniques
When extending a coaxial cable, it is advisable use coaxial connectors. Male and female cable connectors are readily available for this purpose (i.e., etc.). adapters and BNC to BNC, TNC to TNC, 10-32 10-32, These extension cables are available from OMEGA. - Page 13 NOTE The outside shell of these splicing connectors Is the accelerometer signal ground. The splice connector shell should not be allowed to touch ground or conduct to any outside potential or noise source. Letting a connector (which is signal common) touch ground can cause ground loop noise Interjection.

ADHESIVE MOUNTING BUSHINGS An adhesive mounting bushing may be bonded to an object so that the accelerometer may be screwed into the bushing rather than into the object being measured. This is appropriate for those applications where it is not practical to drill into an object for stud mounting. - Page 17 Figure 7-3. Magnetic Mounting...

Page 18: Specifications
BASIC SENSITIVITY OMEGA's low impedance accelerometers are standardized Into two major output sensitivity groups: 10mV/g and 100mV/g. The basic sensitivity specification represents the output of the accelerometer as measured at 100 Hz. Of course, the basic sensitivity varies from one unit to the next within fixed limits. -
