EWD-H-XJ4 Elevator Load Weighing Device
Introduction Manual:
This system is applicable to all elevators with movable platform car (containing 4-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.
3.Set 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 kinds of traction elevator with movable platform car.
8.Integrated structure design: small size, easy installation.
