Description

The BWSENSING BIS341 utilizes a sophisticated MEMS (Micro-Electro-Mechanical Systems) sensing element to provide stable and repeatable angle measurements across two perpendicular axes. This technology translates minute changes in gravitational force into precise digital angle data, making it ideal for structural health monitoring and platform leveling where long-term stability is critical.

Engineered for industrial environments, the sensor incorporates signal conditioning and digital filtering to deliver reliable performance despite vibration and thermal drift. Its IP67-rated enclosure provides robust protection against dust ingress and temporary water immersion, ensuring operational integrity in outdoor, construction, and heavy machinery applications.

Key Features

  • Dual-axis (X & Y) MEMS inclinometer with ±90° full-scale range.
  • High measurement accuracy of 0.01° and ultra-fine resolution of 0.001°.
  • Industrial-standard RS485 interface with Modbus RTU protocol support.
  • Ruggedized IP67-rated aluminum or stainless-steel housing for extreme environments.
  • Wide operating voltage range of 9–35V DC with low 20–40mA current consumption.
  • Extended operational temperature range from -40°C to +85°C.
  • Configurable output data rate, adjustable up to 100Hz for real-time monitoring.
  • High shock resistance (2000g) and excellent long-term stability (MTBF ≥ 90,000 hours).

Applications

  • Structural health monitoring of bridges, dams, and towers for tilt and settlement.
  • Platform leveling and attitude control in construction machinery and aerial work platforms.
  • Real-time inclination monitoring for solar tracker systems to optimize panel alignment.
  • Precision alignment and grade control in agricultural and mining equipment.
  • Anti-tipover safety systems and rollover protection for heavy vehicles and cranes.

Frequently Asked Questions

What is the communication protocol of the BIS341 sensor?

The BIS341 primarily utilizes an RS485 serial interface configured for the Modbus RTU industrial communication protocol. This allows for reliable, noise-resistant data transmission over long distances, enabling easy integration with PLCs, SCADA systems, and data acquisition units. It may also support RS232 and TTL-level serial outputs for shorter-range connections.

What is the operating voltage range for this inclinometer?

The sensor operates from a wide-range DC power supply of 9 to 35 volts. This makes it compatible with common industrial power sources such as 12V or 24V vehicle/equipment batteries and standard 24V DC PLC power rails without requiring an additional voltage regulator.

How do I mount and calibrate the BIS341 sensor?

Mount the sensor securely to a flat, stable surface using the provided or appropriate mounting holes, ensuring its X and Y axes are aligned with your measurement reference planes. Initial calibration for zero offset is typically performed via software commands sent over the Modbus interface to set the current position as the zero-angle reference, eliminating installation errors.

Is this sensor suitable for outdoor use?

Yes, the BIS341 is designed for harsh environments. Its IP67-rated enclosure provides complete protection against dust ingress and can withstand temporary immersion in water up to 1 meter for 30 minutes. Combined with its extended operating temperature range of -40°C to +85°C, it is well-suited for outdoor, construction, and industrial applications.
