PRELIMINARY 13207A Uniaxial ±10 g to ±70 g Accelerometers with Wide Bandwidth to 10 kHz 23207A Biaxial 00001 1911A Technical Data* Features and Benefits High Accuracy and Linearity over Wide Temperature Range The Voltage output for each axis of the 13207A and 23207A is directly proportional to the acceleration along that axis. Each DC-coupled output is fully scaled, referenced, and temperature compensated. Accuracy is improved by minimizing variations due to temperature and aging effects, resulting in a sensor that is more stable over temperature than piezoelectric or piezoresistive devices. Calibration Certificate Each 13207A and 23207A is supplied with a calibration certificate listing sensitivity and offset, as well as the 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 to achieve an even higher level of sensor accuracy. Self-Test on Digital Command A TTL-compatible self-test low input causes a simulated acceleration to be injected into the sensor(s) to verify channel integrity. Small Size Complete conditioned uniaxial or biaxial accelerometer in less than a cubic inch. uilt-In Power Supply Regulation B Unregulated DC power from +8.5 to +36 Volts is all that is required to measure acceleration and temperature. Reverse power voltages of up to -80 V can be withstood indefinitely. Transients of +80 V for 550 ms compatible with MIL-STD-704A can be withstood with full operation. Easy Installation Built-in terminal block or cable with 9-pin connector makes it easy to wire. Two through-holes and four tapped holes simplify mounting. Suitable for Harsh Environments The 13207A and 23207A are robust and can be used in harsh environments. The units will survive 4000 g powered or unpowered. Warranty These Measurement Specialties accelerometers come with a three-year factory warranty 13207A.23207A Analog Accelerometer precisionsensors.meas-spec.com Simplify Acceleration and Temperature Measurements The Measurement Specialties 13207A and 23207A accelerometers include a temperature sensor in their small, rugged package. The small size and built-in power regulation allow the 13207A and 23207A to fit where other accelerometers can’t. Choose the bandwidth and range options best suited for your application to measure ±10 g, ±20 g, ±30 g, ±40 g, ±50 g, ±60 g, or ±70 g accelerations on one or two axes. The high repeatability of the builtin temperature sensor allows precise compensation of temperature effects. Alignment data provided on the included calibration certificate can be used to manually correct transverse sensitivity and alignment errors, or when extra precision is required, Option C002, offset compensation is available. Tested over the -40 to +85°C temperature range, the accelerometers have a nominal full scale output swing of ±2 Volts. The zero g output level is nominally +2.5 Volts. Precise values are available on the included calibration certificate. Custom versions of the 13207A and 23207A can be provided for applications which require different range and/or bandwidth. 2236 N.
