    Description:

          Designed by Shanghai Zhichuan Electronic Tech Co., Ltd., CT330MX‐SWP‐N‐YK is a high‐precision dual‐axis inclinometer using NB‐IoT technology for communication. The maximum measuring range is ±30 degrees, with alarm function. The default protocol is CTIOT (based on China Telecom platform), while MQTT (connectable to Onenet platform) is optional. The model can be widely used in geotechnical and structural health monitoring, municipal administration, telecom, public utility and many other areas.

    Features

    All industrial devices are stable and reliable. Extremely low power consumption.

    Note 1: Lithium ER batteries are not rechargeable, otherwise there is a danger of explosion! When the battery is dead, please replace the battery in time, do not charge it!

    Note 2: The annual battery self‐discharge rate is less than 3%, if stocked in this temperature for a year. The self‐discharge rate will be higher than this value if beyond this temperature range.

    Note 1:Resolution refers to the minimum variation that can be detected by the sensor while working in its valid range.

    Note 2:Refer to the time interval at which the device periodically uploads data to the server when the alarm is cancelled.

    Note 3:Refer to the angular error when the product triggers an alarm. For example, if the alarm angle is 3° and the alarm accuracy is

    0.03°, the product XY arbitrary axis angle is less than 2.97°, which will not trigger an alarm. The alarm may be triggered at 2.97°~3.03°,

    and the alarm will be triggered when it is greater than 3.03°.

    Note 4:Refer to the time when the product continues to tilt beyond the alarm angle to trigger an alarm.

    Note 5:At an ambient temperature of 25 ° C, one battery's capacity is 8500 mAh, the battery loss factor is 0.7, and the heartbeat rate is

    24 hours. Average transmission current≈15.5mA,time for single transmission <=30s, T = 8500/(0.21*1+15.5*30/3600/24)/24*0.7 =1151(day)
