Many Senix ToughSonic sensors are available with our “Teach” button. It can be used to set parameters such as the analog output range. Senix invented the pushbutton method of ultrasonic sensor setup in 1990 and it has been universally adopted since then by major sensor makers worldwide. We retain that capability because sometimes an in-situ calibration is the best choice, as in applications where a computer is not possible or available.
Analog range shouldn’t be confused with the operating range. The analog range or window is a region within the overall operating range. Ultrasonic echoes from outside the operating range are ignored. And the analog range within the operating range is the region where the output voltage or output current varies according to measured distance. Consider instantaneous voltage or current output as position data. In a Senix sensor with a pushbutton, the analog range can be set using the TEACH mode.
Teaching either analog endpoint by TEACH button requires a valid target at the required distance. The analog high can be either the nearer or farther point. A simple procedure to set the analog window by pushbutton follows.
The ultrasonic sensor will output a voltage or current proportional with the measured distance between these points.
