It is an industrial tilt switch sensor with reliable, stable performance and good scalability, suitable for various harsh control environments.


    • The Modbus inclinometer sensor uses RS485 hardware differential bus to transmit data, single axis or dual axis is available.
    • The tilt sensor has a built-in high-precision 16 bit A/D differential converter, which can measure the tilt and pitch angle of the sensor output relative to the horizontal plane through a 5-order filtering algorithm.
    • Due to the built-in high-precision digital temperature sensor, the inclinometer sensor can correct the temperature drift according to the temperature value change, ensuring the high repeatability of the tilt sensor, in low and high temperature environments.
    • The output response frequency standard of the inclinometer sensor can reach 18Hz. If you need a higher response frequency, you can contact us for customization.

    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: Inclinometer sensor working principle.

    Inclinometer sensor uses high-performance core control unit, using the principle of capacitive miniature pendulum. Inclinometer sensor uses the principle of earth's gravity. When the inclination unit is tilted, the earth's gravity will produce a component of gravity on the corresponding pendulum, and the corresponding capacitance will change. The inclination angle is obtained by amplifying, filtering, and converting the capacitance.

    Inclinometer Sensor Working Principle

    As shown in the figure, UL is the voltage between the left plate of the pendulum and its corresponding electrode, and UR is the voltage between the right plate and its corresponding electrode. When the inclinometer sensor is tilted, UL and UR will change according to a certain rule. Therefore, ξ (UL, UR) is a function of the inclination angle α: α = ξ (UL, UR)

    About power supply
    The distance from the display panel to a 120 VAC connection is 2 meters, so the default 1 meter power cable for the display panel should work. Can you supply the DC9-36V power supply for the panel display? The distance from the display panel to the sensor is 25 meters, so 2 additional cable extensions will be required. Would you suggest extension cables to do this or can you provide longer cables from the sensors?

    ATO Responded
    1. If your power supply is only 120VAC, then you need to configure a switching power supply to convert 120VAC to 24VDC, and then supply power to the display panel through the 24V switching power supply. We recommend this switching power supply 24V/50W switching power supply, SKU: ATO-SMPS-50-24, input voltage 85~132VAC, output voltage 24VDC, see spec on:
    2. Yes, we can provide longer sensor cables, 25 meters long sensor cables, including 2 meters long display panel power cables. However, you will need to configure the cable for the switching power supply yourself. Specifically, you need to provide the 120VAC power cable and connect it to the 24V switching power cable.
    Convenient, works well
    Recently, our company is conducting on-site survey of the computer room construction. We have high requirements for accuracy and we have bought several other brands before, but the accuracy is not enough. This one has high accuracy, good quality and low price. It works well and is convenient. We will definitely buy these again.
