    3 Axis Accelerometer Sensor Details

    Tips: Selection Guide of Triaxial Accelerometer Sensor.


    Generally speaking, the more sensitive the better. The more sensitive the sensor is more sensitive to changes in acceleration within a certain range, and the greater the change in output voltage, which makes it easier to measure and obtain more accurate measurement values. The minimum acceleration measurement value is also called the minimum resolution. Taking into account the noise problem of the post-amplification circuit, it should be as far away as possible from the minimum available value to ensure the best signal-to-noise ratio. The maximum measurement limit should consider the non-linear influence of the accelerometer itself and the maximum output voltage of the subsequent instrument. The estimation method is: the maximum measured acceleration × the charge/voltage sensitivity of the sensor.

    Whether the above value exceeds the maximum input charge/voltage value of the supporting instrument, it is recommended that if the measured acceleration range is known, it can be selected in the "reference range range" in the sensor index (taking into account the frequency response and weight). At the same time, in the frequency response and weight If allowed, the sensitivity can be considered higher to increase the input signal of subsequent instruments and improve the signal-to-noise ratio.

    Existing reviews of Three Axis Accelerometer Sensor, Current Output
    Optimised output interface
    What sets this sensor apart is its current output interface. It simplifies the wiring and integration process, and the output signal is not affected by cable length, which is a significant advantage in my setup. The sensor's current output is not only reliable but also easily adaptable to various data acquisition systems.

    I like their service very much
    Since I bought a three-axis accelerometer sensor for the first time, I don't know how to use it. I asked the customer service a lot of simple and basic questions, the customer service was not impatient, and the answer to each question was very professional.
