31206B Triaxial Rate Gyro ±50, ±150, ±300, ±600°/sec Ranges < ±6°/sec Offset Stability Technical Data* Precisely Measure Real -World Rates Features and Benefits High Accuracy and Linearity over Wide Temperature Range The voltage output for each axis of the 31206B is directly proportional to the rotational rate along that axis. Each DC-coupled output is fully scaled, referenced, and temperature compensated. Calibration Certificate Each 31206B is supplied with a calibration certificate listing sensitivity and offset needed to ensure rapid and efficient system implementation. Self-Test on Digital Command A TTL-compatible self-test input causes a simulated rotational rate to be injected into all three sensors to verify channel integrity. Small Size Complete conditioned triaxial rate gyro 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 rotational rates on all axes. Suitable for Harsh Environments The 31206B is robust and can be used in harsh environments. The unit will survive 2000 g powered and unpowered. Three Year Warranty Measurement Specialties 31206B Triaxial Rate Gyros are covered by a three year return to factory warranty. 31206B Analog Rate Gyro precisionsensors.meas-spec.com Measurement Specialties’ 31206B Triaxial Rate Gyro is capable of sensing angular rate around three orthogonal axes. Fully temperature compensated analog outputs are available for the X, Y and Z axes. Choose the range option best suited for your application to measure ±50°/ sec, ±150°/sec, ±300°/sec, and ±600°/sec rotational rates on each of three axes. Each axial sensor has been tested over the -40 to +85°C temperature range and has a nominal full scale output swing of ±2 Volts. The zero rate output level is nominally +2.5 volts. Precise values for each axis are available on the included calibration certificate. Custom versions of the 31206B can be provided for applications which require different ranges and/or bandwidths. 2236 N.
