Product Description:

EWD-RLG-SJ3 elevator load weighing device

l This system can be adopted to all kinds of fixed car 2:1 traction drive elevator with three-way programmable switch output.

l Main features:

1. Equipped with variety of intelligent sensors: A. Ultrathindisctype load sensor to direct detect the changes of the car load, there is no need to change the traction taper sleeve rodB. Choosing the character intelligent tension sensor with easier installationC. The convex stress intelligent sensor is specially suitable for elevator manufacturer. D. Adopting the character load sensor.

2. All operating parameters can be set at the spot.

3. The unique programmable output signal control method can meet the the requirements of the weighing signal of varieties of fixed car platform.

4. It is easy to operate the self-learning model at the spot. The user can choose 20~100% rated self-learning model or rated set modelfor type A, quite easy to operate.

5. With the ability to amend the working parameters automatically and

self-adoption intelligent landing compensation.

l Technical parameters



Being applicable to all traction elevators fixed car platform (less than 60 landings) with the load of 500kg-5000kg.


Floor Compensation

Auto accommodating to the following compensation methods: Up and down leveling; Up command +door zone; Fuzzy and intelligent.



Elevator Rated Capacity/200 (Example: The rated capacity is 1000kg, and the sensitivity is 5 kg) [This data may be affected by elevator mechanical performance]


System error







The method of circuit parallel connection is applicable to the signal source system of DC 12-32V. Also, the interior fault of this system does not affect the original operation mode of elevator.


Output mode


Programmable universal signal

3-channel programmable output models are: no load, light load, semi load, full load, heavy load, rated load, and overload(customer may set the changing range freely.)

Each channel can be programmed as dynamic Close or Open contact.

Description of the System Controller Terminals

l Working principle and installation method:

With the adoption of highly accurate intelligent ”tension” or ”load” and “stress” sensors, the electric signal produced by elevator car load changing is tested and inspected. System sensor installed at the traction rope hitch: Type “EWD-LG-SJ3”With the adoption of serial communication technology, the signal can be transmitted remotely,

highly accurately without loss.Type “EWD-RLG-SJ3”There is an 8-meter-long signal transmitting cable with the sensor. And the single-chip built-in the controller may do scientific calculations fulfilling the aim of weighing the effective load in elevator car.

Sensor of EWD-GA/ GB/ GC/ GD



1. For sensor in conjunction with EWD-GW1transducer, a cable

of 1 meter long is supplied with it.

2. For directly connected sensor, default length of the cable supplied with it is 8 meters.

Q:Can the nylon vacuum packing bag be high and low temperature with mechanical parts?
2 、 nylon vacuum packing bag has strong function:High temperature resistant to oil, humidity and resistance to 90 degrees Celsius, low temperature, freezing, quality preservation, freshness preservation and odor protection. It can be used in vacuum packing, aseptic packing and inflatable packing. [another special high temperature retort bag, >100 degrees]3 、 nylon vacuum packaging bags are of low cost:Compared to glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, CO extrusion film has a greater advantage in cost. Due to the simplicity of the process, the cost of the film products produced can be reduced by 10-20% compared to dry composite films and other composite films
Q:What should we pay attention to when choosing the quantitative packing machine parts?
You look for it. If not, try another one. If you don't understand, you can chase me. I'll explain it to you slowly.
Q:Hardware, furniture accessories, packaging machines exported much?
Not much, but not less, the general exports in several countries around China, Europe, the use of hardware, furniture fittings, packaging machines are not many
Q:What are the components of mechanical equipment (automatic equipment)?
Most of the mechanical parts have national standards, in the design as far as possible the use of standard parts, in the market is easy to find, also don't need to find all factory custom, non-standard parts customization, the price must not cheap. Of course, if it is a robot, it must be customized, and the material is not ordinary steel.
Q:Air conditioning installed in the outer machine packaging, found a small part, please master to help see what is this?
Maybe the workers were not caught in the right place and they fell off during the transportationAfter installation, the blade is unbalanced, the sound of the outdoor fan will increase, and the long time use will also affect the durability of the outdoor fan motor
Q:After the powder metallurgy parts are machined, how to prevent rust?
2, improve the way: Immersion replacement type rust preventive oil, in fact, the base oil or kerosene based, but added a corrosion inhibitor, can improve rust prevention period, about 6-12 months.
Q:A workshop needs to be packed with machine parts. 5 boxes are packed in 80
5 boxes, 80 boxes, =16 20 boxes, only 320 can not be loaded
Q:Single vacuum packaging machine accessories, vacuum schedule, where to sell?
Vacuum packaging machine parts, it is best to buy from the original manufacturers, because many vacuum packaging machine, although the main technology is similar, but there will be many differences in detail, size will vary
Q:What assembly does the vacuum packer require?
The core component is the vacuum pump, and then the control system, the mechanical framework
Q:What kind of material is better for food packing box?
In addition, polyester fibers can be spun into polyester fibers. It can be made into film, used for recording, video recording, film, film and so on substrate, insulating film, product packing and so on. As plastic, it can be made into various bottles, such as coke bottle, mineral water bottle and so on. Can be used as electrical components, bearings, gears and so on.
