Elevator load weighting device EWD-H-XP1 use for passanger elevator
from china supplier
Type EWD-H-XP1 Elevator Load Weighing Device
INTRODTION MANUAL
● This system is applicable to all elevators with movable car
platform and energy-saving operation escalator in need of overload
signals. This 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.
1. Working in a contact less 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 Electromechanical Commission (IEC).
- 4.More accurately positioning, small overall size, easy
installation and adjustment, simple structure and low price.
⒈ | Application Range | Applicable to all elevators with movable car platform in need of
overload signal with a inspection clearance of 8～15㎜. |
2 | Sensitivity | Overload turning point≤Rated load adjusting point±0.05㎜ |
3 | System Error | ≤1.5% (5～40℃) |
4 | Output Mode | 1 pair of relay dynamic CLOSE or dynamic OPEN contacts respectively
with the capacity of DC/AC 48V/500mA. |
5 | Operation Ambient Temperature | -25～55℃ |
6 | Power Supply | AC/DC 24V(±10%)/15mA. The operating current of the whole
machine≤100 mA. |
7 | Install Position | Movable elevator car platform |
8 | Overall Size | Column of Φ24×83 mm |
This system weighs the elevator car load based on the principle of
the elastic deformation of movable elevator car platform caused by
loading with the HALL sensor measuring the change of displacement,
fulfilling the aim of load weighing.
- 1.Please refer to the above figure to install this device with the
connecting support (made by the customer himself) closing 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 aiming 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 load, adjust this device up and down to
make the indicator turn on on the process(or vibration). Fasten the
device and the debug finishes.

If there is any abnormality during adjustment or operation, contact
our company directly.
- Attention: The inductive magnet is specially made of rare earth
magnet with strong magnetism for this product. Take special care in
the course of installation. Don’t let it close to the high
temperature above 100℃ to avoid demagnetization and our company
will not be responsible for the personal hurt and equipment damage
arising from this.
