It is designed for industrial applications requiring precise leveling and slope measurement under harsh environmental conditions. ### 1. Technical Specifications The following table summarizes the core electronic and physical characteristics of the device: | Feature | Specification | | :--- | :--- | | **Measurement Axes** | Dual Axis (X and Y) | | **Measuring Range** | ±10° to ±30° (Configurable) | | **Output Interface** | RS232 / RS485 (Digital) | | **Resolution** | 0.001° | | **Accuracy** | 0.01° (at room temperature) | | **Input Voltage** | 9V – 36V DC | | **Operating Temp** | -40°C to +85°C | | **Protection Rating** | IP67 (Waterproof/Dustproof) | --- ### 2. Key Electronic Components & Technologies The sensor integrates several sophisticated electronic subsystems to ensure reliability: * **MEMS Sensing Element:** Utilizes Micro-Electro-Mechanical Systems (MEMS) technology. It measures the change in capacitance as a proof mass moves due to gravity, converting physical tilt into an electrical signal. * **MCU (Microcontroller Unit):** An onboard high-speed processor performs real-time filtering and linearization. It converts raw analog data from the MEMS sensor into digital degrees or radians. * **Digital Filtering:** Employs Kalman or Low-pass filtering algorithms to suppress noise caused by vibrations and mechanical shocks, ensuring a stable output even in moving machinery. * **Temperature Compensation:** Includes an internal temperature sensor that adjusts the output dynamically to counteract "thermal drift," ensuring the zero-point remains accurate across the full temperature range. --- ### 3. Connection and Wiring The device typically uses a standardized industrial connector (often an M12 or similar circular connector). The electronic pinout generally follows this logic: | Pin | Function | Description | | :--- | :--- | :--- | | 1 | VCC | Power supply input (Positive) | | 2 | GND | Power supply ground (Negative) | | 3 | RX/A | Receive Data (RS232) / Data A (RS485) | | 4 | TX/B | Transmit Data (RS232) / Data B (RS485) | --- ### 4. Typical Applications * **Heavy Machinery:** Leveling of cranes, aerial platforms, and excavators. * **Solar Tracking:** Precise positioning of PV panels to maximize sun exposure. * **Structural Monitoring:** Measuring the tilt or deformation of bridges and buildings. * **Marine Equipment:** Monitoring the pitch and roll of ships or offshore platforms.
