0.1° General-Purpose RS485 Inclinometer

Description

The DR-INC-100-R-D-90-IP68 is a general-purpose inclinometer with 0.1° absolute accuracy and RS485 output, for applications that need full-range angle feedback rather than laboratory precision. This general-purpose inclinometer covers ±10° / ±30° / ±60° / ±90° with 0.1° absolute accuracy, 0.01° resolution, and 100 Hz output, which suits vehicle leveling, aerial platform tilt, solar tracker angle, and general attitude control. Modbus RTU keeps the harness to one shielded pair, and the IP67 / IP68 (customizable) housing with a -40°C ~ +85°C rating works outdoors on a mast, a chassis, or a tracker frame.

Key Specifications

Where This Sensor Is Used

• Vehicle leveling — on-board chassis and body tilt for leveling systems, stabilizer legs, and suspension control, where the ±90° default covers the full mechanical travel.
• Platform tilt — aerial work platforms, scissor lifts, and tilt-bed trailers that need a continuous angle reference across their working envelope.
• Solar tracker angle — single- and dual-axis tracker position feedback, so the controller can confirm the drive reached its commanded angle.
• Attitude control — general industrial tilt feedback on hinge arms, gates, ramps, and adjustable frames where 0.1° is enough and cost matters.
• Slope and geological monitoring — surface tilt measurement on slopes and retaining structures at the coarse end of the monitoring scale.

Why Choose Drksir

• 15+ years designing and manufacturing tilt sensors for industrial and infrastructure monitoring
• 3,000+ projects delivered across civil engineering, renewable energy, and transportation
• Full range of industrial inclinometers from 0.1° to 0.001° accuracy, sharing one Modbus RTU register layout
• ±90° full-range coverage in the same housing as the high-accuracy tiers †
• IP67 / IP68 protection options for harsh environment installation
• Average service life ≥55,000 hours
• 24-month warranty and lifetime application engineering support

How It Compares to Alternatives

• Versus the 4-20mA version of the same sensor — identical mechanics, accuracy, and dimensions; RS485 keeps the harness to one twisted pair and allows several sensors on one bus, while 4-20mA suits analog input cards
• Versus high-accuracy (±30° range class) inclinometers — same housing, wider arc, 0.1° absolute accuracy; the right choice when the requirement is a position reference rather than a settlement measurement
• Versus potentiometer-based tilt sensors — no wiper wear, no dead band, no mechanical limit, and no calibration drift from contact erosion
• Versus consumer-grade MEMS modules — industrial -40°C ~ +85°C rating, IP-rated housing, and a Modbus interface instead of uncalibrated raw output

Installation & Wiring

Mount the sensor on a flat, rigid surface (steel bracket or concrete anchor recommended). For highest accuracy, align the sensor’s X-axis to the primary direction of expected tilt.

The sensor uses a 4-core shielded cable for power and data:

For RS485 cable runs over 100 m, use shielded twisted pair and terminate the shield at one end only. Maximum recommended cable length is 1,200 m at 9600 baud.

OEM/ODM & Customization

Standard units ship from stock within 5 business days. Custom measuring ranges (±10° / ±30° / ±60° alternate to default ±90°), cable lengths, connector types, and protection-grade options (IP67 vs IP68) are available for OEM/ODM orders starting at 50 units. Typical custom lead time is 15-25 business days. Engineering drawings and integration support are provided free of charge.

FAQ

Q: Which measuring range should I select?

A: Select the smallest range that covers your expected travel. Accuracy is 0.1° across all four options (±10° / ±30° / ±60° / ±90°), so the choice is about arc, not precision. The ±90° default suits vehicle leveling and platform work that uses the full mechanical travel; a mast or frame that stays within a few degrees can use a narrower range. The default SKU ships with ±90°; other ranges are configured at the factory on request.

Q: What if I need higher accuracy?

A: The wired inclinometer family covers 0.1° to 0.001° in one housing family. For a wider arc at tighter accuracy, the 0.01° Industrial-Grade RS485 Inclinometer holds 0.01° at ±10° and ±30°. For tower and machine work, the 0.005° High-Precision RS485 Inclinometer holds 0.005° across ±5° to ±30°. For sub-millidegree structural monitoring, the 0.001° Ultra-High Accuracy RS485 Inclinometer reaches 0.0005° resolution.

Q: What’s the difference between this sensor and the 4-20mA version?

A: Identical mechanics, accuracy, and dimensions. The RS485 version returns digital values over Modbus RTU and allows several sensors on one bus; the 0.1° General-Purpose 4-20mA Inclinometer outputs a current loop proportional to tilt, preferred where the controller only has analog inputs.

Q: Does the sensor require recalibration in the field?

A: No field recalibration is required for normal operation. Periodic verification against a reference fixture is good practice on any safety-related installation; the interval depends on your site standard.

Q: Can the sensor be used in submerged installations?

A: The IP68 protection option (customizable) is specified for continuous immersion. The qualified depth and duration depend on the sealing configuration — request the datasheet for the figures for your installation.
