US Digital Absolute Optical Inclinometer A2T

Description
The A2T is a single axis, digital gravity angle sensor. The A2T serves as a full 360 range absolute tilt sensing programmable level with either digital or analog output. Internally, a rotary bar coded disk is mounted to a weighted gravity driven wheel. A micro-controller strobes an LED to transfer the bar code image onto an optical linear array, then decodes the position every 2 mSec. Magnetic damping provides fast response and settling time while virtually eliminating overshoot and oscillations. An internal EEPROM stores field programmable parameters such as resolution, zero position, direction swap, and mode. This second generation design virtually eliminates the primary accuracy limitation of first generation inclinometers, which is situation (hysteresis). 12-bit accuracy and resolution field programmable from 2 to 4096 codes per revolution (3600 factory default) Full 360 degrees range, 7 msec update time Low power drain of 16 mA max., and 0.6 mA in sleep mode Field programmable parameters such as setting zero position point (free demo software provided) EEPROM stores downloadable parameters 9600 baud default data rate adjustable up to 115K baud 12-bit analog voltage output option (0 to +3.599 volts factory default setting. Field programmable up to 0 to +4.095 volts) Multi-turn mode (note: power must be maintained to prevent reset to zero) -25 to 70 degrees C. operating temperature Simple, low cost
