23200A Wide Input Voltage ± 10 to ± 75 g Bi-Axial Accelerometers with Signal Conditioning and Temperature Sensor Technical Data* Features and Benefits High Accuracy and Linearity over Wide Temperature Range The voltage output for each axis of the 23200A is directly proportional to the acceleration along that axis. Each DC-coupled output is fully scaled, referenced, and temperature compensated. A force-balanced design improves accuracy by minimizing variations due to temperature and aging effects, resulting in a sensor that is more stable over temperature than piezoelectric or piezoresistive devices. For critical applications, the built-in temperature sensor with very high repeatability can be used to compensate for any residual temperature effects. Calibration Certificate Each 23200A can be supplied with an optional calibration certificate listing gain, offset, and on-axis and transverse alignment parameters needed to ensure rapid and efficient system implementation. The alignment data can be used to compensate the measured values if needed. Self-Test on Digital Command A TTL-compatible self-test input causes a simulated acceleration to be injected into both accelerometers to verify channel integrity. Small Size Complete conditioned bi-axial accelerometer in less than a cubic inch. Built-in Power Supply Regulation A single regulated +5 volt or an unregulated DC power source from +5.25 to +30 volts is all that is required to measure accelerations on both axes. The 23200A is ideal for automotive applications with the ability to survive both continuous reverse battery to -20V and load dump transients to +60V. Easy installation Built-in terminal block or cable with 9-pin connector makes it easy to wire the 23200A. Two through holes and four tapped holes simplify mounting. Suitable for Harsh Environments The 23200A is robust and can be used in harsh environments. The unit will survive 500 g powered and 2000 g unpowered. Simplify Acceleration and Temperature Measurements The Summit Instruments 23200A accelerometer has two orthogonal axes and a temperature sensor in a small rugged package. The small size and built-in power regulation allow the 23200A to fit where other accelerometers can't. A power source of +5 to +30 VDC is all that is required to measure temperature and ± 10 g, ± 15 g, ± 20 g, ± 25 g, ± 30 g, ± 50 g or ± 75 g accelerations on each of two axes. When extra precision is required, the high repeatability of the built-in temperature allows precise compensation of temperature effects and alignment data provided on the optional calibration certificate can be used to compensate for transverse sensitivity and alignment errors. Each axial sensor has been tested over the -40 to +85°C temperature range. Each axis has a nominal full scale output swing of ± 2 volts. The zero g output level is nominally +2.5 volts. Precise values for each axis are provided on the optional calibration certificate. Custom versions of the 23200A can be provided for applications which require different ranges and/or bandwidths. *Data subject to change without notice Rev. 11/01 Specifications TA = TMIN to TMAX, 5.25 ≤VS ≤30 V, Acceleration = 0 g, unless otherwise noted.
