Description
LDA-196-1000CE
Technical Specifications: Measurement stroke: 1000 mm Output signal: 4-20 mA or 0-10 VDC Input supply: 24 VDC Linearity error: ±0.05% full stroke Repeatability: 0.01% full stroke Operating temperature: -40 ℃ to 85 ℃ Protection class: IP65 Mechanical connection: rod end bearings
Functional Features: Contactless magnetostrictive measuring principle. Infinite mechanical life with no wiper wear. Non-contact position detection eliminates signal drift. Integrated signal conditioning electronics. Reverse polarity and short-circuit protection. IP65 sealed housing for washdown environments. Absolute position output no zero-setting required after power cycle.
Application Scenarios: Hydraulic cylinder position feedback, plastic injection molding machine clamp position, press stroke measurement, elevator car position monitoring, materials handling trolley position tracking.
Performance Parameters: Resolution: 0.01 mm Update rate: 1 kHz Maximum cable length: 1000 m with 4-20 mA output Shock resistance: 50 g peak Vibration resistance: 10 g rms, 2 kHz
Material Composition: Sensor tube: stainless steel. Electronics housing: anodized aluminum. Cable: polyurethane jacket. Magnet: rare earth permanent magnet. Rod end: zinc-plated steel with bronze bushing.
Structural Features: Long tubular sensor body with threaded mounting. Floating position magnet travels along sensor tube. Rear electronics housing contains signal conditioning circuit. Multi-core cable exits from rear gland. Dual rod end bearings for pivot mounting.
Working Principle: A current pulse is applied along waveguide inside sensor tube. Position magnet creates local magnetic field. Interaction generates ultrasonic strain pulse that travels along waveguide. Time interval between pulse generation and echo arrival is proportional to magnet position. Signal conditioning electronics converts time measurement into standard 4-20 mA output signal.
Installation Requirements: Mount sensor parallel to travel direction. Ensure position magnet moves freely without contacting sensor tube. Use flexible coupling for piston rod connection. Ground cable shield at control cabinet end. Keep sensor tube away from strong external magnetic fields.
Precautions for Use: Do not bend sensor tube below minimum radius. Protect floating magnet from mechanical collision. Verify output signal matches expected stroke before commissioning. Do not exceed maximum sensor extension speed. Clean sensor tube regularly in washdown environments.
