Introduction

The MEMS inclinometer SINIT can directly output the inclination angle. The data can be viewed through the PC software or serial port tool.
SINIT is a small volume and low-cost dual-axis current output tilt sensor with an output current of 4-20mA. Built-in high-precision tilt unit, low power consumption, it is a high-precision tilt switch. X-axis Y-axis two analog current outputs, angle range -90 degrees to +90 degrees. Real-time monitoring of data on PC Software.

• Dual axis Inclination Measuring: X-axis (-90 degree, 90 degree) Y-axis (-90 degree, 90 degree), Dual-axis Analog 4-20mA Current Output
• Kalman Filtering: Integrated Kalman Filtering Algorithm ensures high-stability of angle data output even in a highly dynamic environment
• 0.1 degree Precision, IP68 Waterproof Protection, Anti-vibration

Warning Statement

• Putting more than 36 Volts across the sensor wiring of the main power supply can lead to permanent damage to the sensor.
• VCC cannot connect with GND directly, otherwise it will lead to the burning of the circuit board.
• For proper instrument grounding: use WITMOTION with its original factory-made cable or accessories.
• For secondary developing project or integration: use WITMOTION with its compiled sample code.

Set the Relative Attitude Angle

After the signal wire (purple) is grounded for two seconds, you can set the current attitude to a relative angle of 0°.

Current Output &Angle Calculation Formula

The SINIT is a standard current output of 4-20mA, which corresponds to the minimum range and maximum range of the angle measurement; the calculated angle is to obtain the corresponding angle value as long as the ratio.
For example: SINIT-90 (4-20mA): means ±90° measurement range, 4-20mA current output.

Product Installation Direction:
The installation should keep the sensor’s mounting surface parallel to the measured target surface. The device can be installed horizontally and vertically, please refer to the following diagram (single axis X, Y optional).

Installation Precautions

Precautions for product installation
Please install the inclination sensor correctly. Incorrect installation will cause measurement errors. Pay special attention to the surface and the two lines.

1. The mounting surface of the sensor and the surface to be measured must be tightly fixed, flat and stable. If the mounting surface is uneven, it will easily cause the angle error of the sensor, as shown in Figure 1, Figure 2.
2. The axis of the sensor and the axis to be measured must be parallel, and the two axes should not have an angle as much as possible, see Figure 3, Figure 4
