Type EWD-H-J3 Elevator Load Weighing Device

INTRODTION MANUAL

This system is applicable to all elevators with movable platform car (containing 3-channel programmable switch signals)

Main characters:

1. Contactless inductive working mode, solid state relay output, no need to fix the original position of elevator overload switch, and to change structure of elevator platform car.

2. Electrical properties is in compliance with the standard of the International Electro-technical Commission.

3Set up all parameters on the spot.

  • 4.Adopt strong inductive magnet, improve the anti-interference ability to the utmost.
  • 5.System carry scientifical computing out according to mathematical equations to automatically amend detention of error. It also has no-load auto zero capacity
  • 6.It is totally convenient to adjust on the pot by means of artificial self-study or artificial displacement.
  • 7.Control method of programmable output signal created by ourself is applicable to all kin.ds of traction elevator with movable platform car.
  • Integrated structure design: small size, easy installation.

Working principle

Referring to diagram, by means of Holzer sensor this system tests displacement changing based on platform car of elevator and load elastic variation principle. It use single chip microcomputer to scientifically compute to correct error in terms of given parameter and measuring results based on mathematic equations, which accomplish effective load weighing of the elevator platform car.EWD-H-J3 elevator load cell,China elevator sensors, elevator load weighing device

Other weighing devices

Working principle

Adopting Holzer sensor. Accomplishing contactless inductive working.
Advantages:
① Has long working life in that this system don't bear load of elevator.
② Width induction & high positioning precision.
③ No system damage arising from insufficient overload capacity and mechanical vibration.
④ Micro sensor & microcomputer make system highly intelligent and lower power waste.
⑤ Automatically amending detection error by means of digital. Good linearity.

Directly bear elevator load by the way of pressure sensor.

Installing method

Only need to fasten the device in the middle of bottom of platform car or original position of mechanical switch in the condition of failure to change structure of platform car. Small size & Easy installation.

Need to change structure of the platform car. Uneasy to install & more work.

Adjusting on the pot

① Thanks to the high intelligence personnel may complete adjustment of elevator weighing device on the spot after separately press the button of sensor two times following the completion of installation system sensor when elevator is no load or rated load.
② Elevator producer may directly complete quick adjustment of similar elevator by the way of setting-up the manual displacement.
Advantages: easy & quick to adjust

Complicated adjustment owing to the analog signal.

Connecting the interface of output signal on the select layer device

3-channel programmable output terminal could be set up by user themselves. Selection: no load, light load, semi-load, heavy load, rated load, overload; 0~10V analog output. It is convenient for user to finalize the items below: 1 vandal resistant function. 2 full bypass function. 3 energy saving function. 4 debugging system torque compensation.

Single function

Economic analysis

① High-performance to price ratio, easy to use, low breakdown.
② Less accessories, low additional cost & simple processing
