Elevator Sensors in Sri Lanka — Position, Leveling & Safety Detection

Sensors are the sensory nervous system of an elevator hoistway. They provide exact millimeter car positioning, floor leveling data, deceleration triggers, and hoistway limit verification to prevent over-travel and abrupt deceleration.

Types of Elevator Sensors Available

• Magnetic & Bistable Reed Switches: Robust car position indicators actuated by hoistway vane magnets for floor leveling.
• Photoelectric & Optical Sensors: High-speed optical sensors for door position, car gate verification, and safety curtain monitoring.
• Proximity & Inductive Sensors: Non-contact metal detection sensors resistant to hoistway dust, oil, and vibration.
• Load Weighing Sensors: Under-car and rope-hitch strain sensors that calculate passenger payload and signal overload conditions.

Replacement & Alignment Advice

Faulty leveling sensors cause car leveling discrepancies at landing sills (a primary passenger tripping hazard). Ensure sensors are properly aligned with hoistway flags and free of metallic debris.
