Mounting Methods Clamping flange, synchronous flange, blind hole clamping, etc., adaptable to different mechanical structures
⚙ II. Technical Principles and Working Characteristics
Absolute vs. Incremental
Absolute encoder (e.g., 01075-111): Each position corresponds to a unique digital code, no need for homering upon startup, no cumulative error, suitable for high-reliability positioning in petroleum drilling.
Incremental encoder: Relies on pulse counting, requires recalibration after power loss, susceptible to interference, commonly used for speed monitoring.
Explosion-Proof and Durable Design
Explosion-proof certification: Housing made of high-strength explosion-proof materials (e.g., stainless steel), internal circuit isolation design to prevent electrical sparks (compliant with petrochemical explosion-proof requirements).
Vibration resistance: Reinforced mechanical structure, adaptable to high-frequency vibration environments of drilling rigs.
Signal Processing
Baud rate and refresh: Default communication baud rate 9600 bit/s (up to 115200 bit/s), refresh cycle approximately 1.5ms, ensuring real-time data transmission.
Anti-interference capability: Push-pull output or differential signals (e.g., TTL long-line驱动), reducing long-distance transmission errors.
