Digital Hanging Scale type:

Form from the work can be divided into hanging hook, driving style, the axis pedestal, embedded four; from reading straight form the body can be divided into explicit scale (ie, body sensors and scale integration), cable box operation Display (crane operator control), large screen display and wireless instrument display (and computer networking) four; form from the sensors can be divided into resistance strain, pressure magnetic, piezoelectric and capacitive four; resistance strain most commonly used. From the use of the environment is divided into normal temperature type, high temperature, low temperature, magnetic insulation type and explosion proof; from the data processing on the stability can be divided into static type, quasi-dynamic model and dynamic model of three; currently used for static and quasi-dynamic model, dynamic model have begun to enter the market, such as e-like animal weighing scales.

Electronic crane scale of the main advantages and disadvantages

⑴ Reduce operating links, speed up the measurement of speed, saving manpower, material and time, so that the goods in the lifting, loading and unloading complete measurement.

⑵ Does not account for space, easy to use and flexible.

⑶ Allows continuous measurement of the work, and play a role in monitoring and control. As in the nonferrous metals industry of the electrolysis plant, metallurgy casting occasion, a timely monitoring of Lv (steel)-water in Lv (steel) weight of the water reaches the maximum use of equipment, saving energy Mudi.

⑷ Measurement data to achieve remote, centralized monitoring, people leave the poor and dangerous working environment.

⑸ Easy and crane control systems combine to reduce the job setting. Our newly developed multi-purpose crane for electrolytic aluminum plant unit electronic crane scale , crane remote control with the organic combination.

⑹ Easy metrological verification, error correction is simple.

⑺ Multi-function, high precision, strong anti-cheating, low maintenance costs.

⑻ Hook hanging crane Luggage scales crane lifting of the height of the goods, driving style, the axis pedestal cranes needed transformation, maintenance of crane operations, the embedded part in the installation of a crane weighing links, does not affect play lift height, does not affect crane operations, is the development of the industry in one direction.

Electronic crane Hanging scale works and the main parameters

1. How it works: When the load acting on the sensor through the hook to make the sensor small changes occurred elastomer, so that the body attached to the elastic resistance of the resistance strain gauge changes, changing the balance of the bridge. The output voltage changes, changes in the voltage signal through the high-speed precision A / D converter into digital signals, the digital signal by the collector, the wireless transmitter (or cable) to the secondary instrument inside. Secondary instrument will be calibrated data signal processing, the weight values ??to the corresponding screen display, a printer can print, if necessary, can be transmitted to the computer management system.

2. The main technical parameters

⑴ Executive Standard: GB11883-89 electronic crane standards, with n said sub-degree (precision), e said division value (sense of volume), tolerance by e said.

⑵ Accuracy:

A. 1000 international standard OIML Ⅲ class

B. Standard of domestic A-1000

C. Class B standard of 400 domestic
