WitMotion SINET Dual-Axis AHRS Tilt Inclinometer, 0.1 Accuracy, 0.01 Resolution, Alarm, RS232/RS485/TTL, IP67 (936V)

Overview

WitMotion SINET is a compact, industrial dual-axis AHRS inclinometer with a built-in tilt alarm. It measures X/Y tilt from 0 to 90, provides switching (voltage) alarm output with a configurable threshold (default 10), and communicates via TTL/RS232 (RS485 optional per spec banner). The rugged aluminum alloy housing is IP67 sealed and survives high shock and vibration for outdoor machinery, vehicles, lifts, and antenna positioning. Power is a wide 936 V DC input.

Key Features

• Dual-axis tilt monitoring (X, Y), 0~90

• High precision: full-range 0.1 accuracy; 0.01 resolution

• Fast response: up to 100 Hz (DC response)

• User-settable alarm threshold (default 10); switch output, default level high (PC software adjustable)

• Wide supply: DC 936 V, typical 12/24 V

• Ruggedized: IP67, aluminum shell, anti-vibration 10 grms (101000 Hz), impact 3500 g/0.5 ms (3/axis)

• Wide temperature: 40 +85 C operation

• Small size: 55 36.8 24 mm; four M4 mounting screws

• Quick start: 0.5 s power-on time

2. Black GND

3. Green RX (device receives)

4. Yellow TX (device transmits)

5. White +X alarm output

6. Gray X alarm output

7. Blue +Y alarm output

Interfaces: UART TTL or RS232 (ordering option). Alarm default output level is high (software-configurable).

Installation Notes

• Mount the sensor flat and rigid to avoid tilt errors; the mounting surface should be smooth/level.

• Keep the sensor axes parallel to the measured axes (see diagrams).

• May be installed horizontally or vertically (right-hand coordinate rule).

• Use the purple wire zeroing function to calibrate the current position to 0 after installation.

Typical Applications

• High-voltage line/pole monitoring

• Satellite & solar antenna positioning

• Aerial work platforms and vehicle leveling

• Medical equipment angle sensing

• Pan/Tilt mechanisms

• Hydraulic lifts

• General construction machinery angle control and tilt-based monitoring
