DIS331
Voltage Single-Axis Inclination Switch
Designed by Bewis Sensing Technology LLC, The DIS331 series is a single-axis inclination switch, with
a measuring range of ±180°. 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). Thanks to the
built-in solid state relay, the user does not need to reconfigure the extra relay. The maximum current
in the normally closed state can reach 1A. The alarm threshold can be set according to the actual
situation. The product is small in size, high in consistency and stability, its working temperature
reaches the industrial grade -40℃~+85℃, which is a cost-effective inclination switch.

Resolution: The measured minimum change value that the sensor can detect and resolve within
the measurement range.
Accuracy: The error between the actual angle and the Root mean square(RMS) of the measured
angle of the sensor (≥16 times).

Secondly, the bottom cable of the sensor and the axis of the measured object shouldn't generate the
angle shown in E. When installing, the bottom cable of the sensor should be kept parallel or
orthogonal to the rotation axis of the measured object. This product can be installed horizontally or
vertically (vertical installation requires customization). The correct installation method is shown in
Figure F.
Finally, the installation surface of the sensor must be fixed with the measured surface tightly and
smoothly, to avoid measurement error that may be caused by the acceleration and vibration.

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.

Debug software
Users can directly download serial assistant on official website (Supports-Download). You can also use
more convenient and intuitive PC software.
DIS331 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.
①

③
Correctly connect the inclinometer serial port hardware and connect the power supply.
Select the computer serial port and baud rate and click connect Serial Port.
Click Start and the tilt angle of the tilter in the X direction will be displayed on the screen.
Software use steps:
Note: You can switch to Chinese or English version by the bottom left button.
