    Elevator load weighting device/ elevator parts load cell EWD-H-P1

    Type ECW-P1 Elevator Load Weighing Device/ elevator load sensot/elevator parts

    Picture for your reference:


    This system is applicable to all elevators with moveable car platform in need of overload signals and escalators in need of energy saving. This device is of extremely high ratio of property to price. Its appearance is to overcome the inherent disadvantage of the mechanical overload switch and to replace it.


    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.


    Technical Specification:


    1Application RangeApplicable to all elevators with moveable car platform in need of overload signal with a inspection clearance of 8~15㎜.
    2SensitivityOverload turning point≤Rated load adjusting point±0.05㎜
    3System Error≤1.5% (5~40℃)
    4Output Mode1 pair of relay dynamic CLOSE and dynamic OPEN contacts respectively with the capacity of DC/AC 48V/500mA.
    5Operation Ambient Temperature-25~55℃
    6Power SupplyAC/DC 24V(±10%)/15mA. The operating current of the whole machine≤100 mA.
    7Install PositionMoveable elevator car platform
    8Overall SizeColumn of Φ24×70 mm

    Working Principle:


    This system weighs the elevator car load based on the principle of the elastic deformation of moveable elevator car platform caused by loading with the HALL sensor measuring the change of displacement, fulfilling the aim of load weighing.


    Installing Method:


    Adjustment:

    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 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.

    5.The principle of system wiring:

    Comparison of the functions with other load weighing devices:


    ECW-P1Mechanical overloading switch

    Working Principle

    By the use of Hall sensor, the working way of contactless induction is realized.

    Advantages:①The system doesn’t bear the elevator load directly, extending its life.②Overloading signal is of point turning to position more accurately.③No system damage caused by the insufficiency of overloading competence or mechanical vibration.

    Directly bearing the effect and impact of elevator load, unstable and damageable.
    Installing and adjusting

    Just adjust the system up and down so that the indicator will turn from dark to bright. At the turning point, fasten this device well.


    Field adjustment is complicated.

    Output signal

    A pair of relay dynamic Close and Open contacts respectively.Single function
    Economic Analysis⒈High ratio of property to price, easy use, high reliability.

    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.
