Description

INSA-6120-RS485 Modbus Single-Axis Inclinometer
Introduction
INSA-6120-RS485 is a digital output low-cost single-axis inclinometer, adopting the latest industrial
level MEMS accelerometer. Its measuring range is ±180°, highest accuracy of 0.3°, working
temperature is –40ºC ~+85ºC, the product with a small-volume and low weight, can meet space restricted application requirements.
This product converts static gravity field changes into angle changes, It outputs horizontal angle
values directly by digital, this product has the advantages of low-cost, small temperature drift, simple
to use, and strong resistance to external disturbances. It is an ideal option for attitude measurement
in photovoltaic power (PV), PTZ control, tower turbines monitoring and other industries.

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.

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.
