2.1 Range Selection
Application | Recommended Range | Product Selection & Rationale |
Robotic arms/mobile AGVs | ±180° (full orient) | TS-6613-R02-485±180° range for joint rotation; auto-calibration corrects AGV misalignment. |
Structural monitoring | ±5° to ±15° | TS-6423-R03-485:±0.01° accuracy detects micro-deflections in bridges. |
Industrial cranes | ±30° to ±45° | TS-3420-R01-CAN:CAN bus ensures EMI immunity; compliant with ISO 9001 and ISO26262. |
Solar trackers (cost-opt.) | ±60°–90° | TS-2322-R04-10V:Dual-axis 0–10V analog; reduces system costs while meeting CE IEC 61326-1:2021. |
Geotechnical boreholes | ±1° (high prec.) | TS-6623-R06-024: 0.001° resolution for soil creep monitoring. |
General monitoring | ±90° | TS-2312-R03-485: Single-axis Modbus; *IP67-rated with industry-leading cost efficiency*. |
Key Insight: Narrow ranges (±1°–15°) maximize micro-movement sensitivity; wide ranges (±90°) suit dynamic systems.
