- Page 2 Voltage Dual-Axis Inclination Switch Introduction Designed by Bewis Sensing Technology LLC, The LIS344 series is a dual-axis inclination switch, with a measuring range of ±90°. When the measured inclination angle exceeds the alarm threshold, the output line becomes closed (disconnected is also available). If the measured inclination does not exceed the alarm threshold, the output line is normally open (also normally closed).

Page 5: Installation Direction
LIS344 Voltage Dual-Axis Inclination Switch Installation direction The correct installation method can avoid measurement error. The following points should be made when installing the sensor: First of all, to ensure that the sensor mounting surface and the measured surface completely close, the measured surface should be as horizontal as possible, can not have the angle shown in Figure A and Figure C, the correct installation is shown in Figure B and Figure D. -

You can also use more convenient and intuitive PC software. LIS344 supporting serial debugging software can be connected to the inclinometer on the computer for angle display. The software debugging interface is as shown in the figure below. Using the debug software, it can conveniently display the current X-direction tilt angle, and you can also modify and set other parameters by yourself.
