Ningbo SENSONG Electronic Technology Co.,Ltd
SENSONG brand Hall Effect Type ELW01 Lift Overload Weighing Sensor Device is applicable to all elevators with moveable car platform in need of overload signals.
This load weighing device is of extremely high performance-price ratio. This appliance is to overcome the inherent disadvantage of the mechanical overload switch and to replace it.
• Working Principle
This system weighs the elevator car load based on the principle of the elasticdeformation of movable elevator car platform caused by loading with the HALL sensor measuring the change of displacement, fulfilling the aim of load weighing.
• Main Property
1. Working in a contactless and inductive way. No mechanical movement itself. Being directly installed in the original place
of overload switch. No necessity of changing the mechanism of elevator car.
2. Adopting strong inductive magnet, improving the anti-interference of the system to the utmost.
3. The electrical property is in compliance with the standard of the International Electrotechnical Commission (IEC).
4. More accurately positioning, small overall size, easy installation and adjustment, simple structure and low price.
• Adjustment
1. Please refer to the above figure to install this device with the connecting support (made by the customer himself) close to the
middle part of the car platform as near as possible.
2. Let the magnet adhesive on the car platform with the marking-face right facing the induction point of the device.
3. Install and adjust this device so that the magnet on the car platform aims at the center point of its upper face.
Meanwhile, assure the end face of this device in parallel with that of the magnet.
4. When elevator is of rated loaded, adjust this device up and down to make the indicator just turn from dark to bright
(or oscillating), at this time, fasten this device and the adjustment is finished.
