Basic requirements for wireless crane scale operation

Basic requirements for wireless crane scale operation The wireless crane scale consists of a scale body and an instrument. Among them, the scale body uses a crane scale special high-precision resistance strain sensor (patent product) and high-reliability force transmission structure, the instrument part features advanced, intelligent degree, the product is suitable for weighing measurement within the specified range. And have the following features:

The instrument is small, light and very suitable for portable use.

The backlit display is clearly visible during the day and night.

There is a calendar clock for 10,000 years.

Built-in EPSON mini printer can print complete weighing data and print by date, serial number and serial number.

The weighing results can be divided into up to 9999 categories and classified and printed.

Large storage space, can store 2900 0 records.

The meter has a low voltage on the scale and a low battery voltage indicator.

Overload alarm, safe and reliable.

Automatic shutdown: When the scale is left standing for 2 hours, it will automatically turn off the scale body power;

First, the composition of wireless crane scales:

General wireless electronic crane scale is composed of wireless meter, scale body, trolley, wireless transmitter (in the scale body), wireless receiver (in the instrument) charger, antenna, and battery.

Second, wireless crane scale working principle:

Hang the hanging rings of the electronic crane scales on the crane hooks. When the electronic crane scale hooks on the hooks, the sensors in the scale body are deformed by tension and the current in the sensor changes, and then the current changes. A/D conversion, and then send the radio signal through the transmitter, according to the provisions of the National Radio Management Committee, electronic crane scale is generally issued with 230MHZ and 450MHZ, the receiver receives the signal and then transmitted to the instrument, and then through the conversion of the meter Finally, it shows three, wireless crane scale features:

1. Universal Meter: The SR meter is an intelligent receiving monitor, which can be used with various tonnage OCS-type electronic crane scales without the need of calibration. It realizes the real sense of universality and is a domestic initiative.

2, easy to operate: The instrument uses a large-screen dot-matrix LCD display, and with background light. According to the need to set Chinese characters, the operation to adopt the keyboard and the Chinese menu "order" approach, without training, convenient operation, to fill the domestic blank.

3. Adopting intelligent data transmission, non-metering status, intermittent transmission of data by the transmitter, reducing the number of charging, prolonging the life of the transceiver 4, large-scale integrated electrical appliances, modular design, and supporting the use of a variety of strain-type electronic weighing equipment. Password anti-counterfeiting: calibration in the body, with a calibration password, anti-counterfeiting and anti-counterfeiting ability 6, unique anti-repetition printing function, can block management loopholes 7, the frequency of the transceiver can be arbitrarily exchanged according to user needs, and can be strong Normal working under magnetic field 8. Unique weighing structure (patented technology) to ensure system accuracy is better than international OIML III standard
