    High accuracy inclinometer sensor has 4-20mA current output, ±10°~±180° measuring ranges and horizontal or vertical installation for selection. It is a single-axis/2-axis tilt sensor, suitable for bad industrial working conditions.


    • The inclinometer sensor outputs 4-20mA standard current, transmission distance is up to 2000 meters.
    • Output signal of the single/dual axis inclinometer has strong anti-interference, which is dedicated to engineering machinery and equipment working in harsh environments.
    • The tilt sensor adopts MEMS sensing production process to make precise compensation and correction for temperature error and nonlinear error. Small range accuracy can reach 0.05°, high precision, small size, high packaging technology, strong shock and vibration ability.
    • Inclinometer sensor has built-in anti-radio frequency and adopts anti-electromagnetic interference circuit, which is especially suitable for underground non-excavation machinery and other harsh industrial environments.
    • In terms of reliability and stability of the industrial inclinometer sensor, it uses industrial-grade MCUs, 3-proof PCB boards, cables, wide-temperature shielded metal casings and other measures to improve its industrial grade.

    Inclinometer Sensor Installation Direction Diagram

    The installation must guarantee the inclinometer sensor bottom is parallel to measured face,and reduce the influence of dynamic and acceleration to the tilt sensor. This inclinometer sensor can be installed horizontally or mounted vertically, for installation please refer to the following scheme.

    Tips: Definitions of inclinometer sensor key specifications.

    • Resolution: It refers to the smallest change value of the measured value that can be detected and distinguished by the inclinometer sensor within the measurement range.
    • Absolute accuracy: refers to the combined error of absolute linearity, repeatability, hysteresis, zero point deviation, and horizontal axis error of the inclinometer sensor, under normal temperature conditions.
    • Long-term stability: It refers to the deviation between the maximum value and the minimum value of the inclinometer sensor after one year of long-term work, under normal temperature conditions.
    • Response time: It refers to the time required for the sensor to output and reach the standard value when the angle of the inclinometer sensor changes once.
    Existing reviews of Inclinometer Sensor, Output 4-20mA, ±10°~±180°
    Will inclinometer sensor regain its position?
    OK. But will it regain its position once power is restored without need to be zeroed or calibrated?

    ATO Responded
    Once power is restored, the sensor does not need to be calibrated and adjusted, and can directly output the absolute angle value.
    Is this dual-axis inclinometer suitable for machines?
    Is this dual-axis inclinometer suitable for machines? I need one axis 360 degrees and the second axis can be smaller such as 15 degrees.

    ATO Responded
    For an axis of 360 degrees (±180 degrees), it is a single axis, not a double axis. We recommend using our single-axis X-axis to measure the inclination angle of plus or minus 180 degrees. And another our single-axis Y-axis to measure the inclination angle of ±15 degrees or 30 degrees.
    Amazing inclinometer sensor!
    Quite a remarkable inclinometer sensor! This is a great little tool that works as advertised. The quality is great. I have used it for weeks and I think that it is worth to have a high rating!
