Metrology in Digital Era | General Measure Weighing in Digitalization

 

 

 

In an era of the digital world, all the industries are looking for integrating digital technologies into their existing infrastructure of applications to transform the way they work and increase efficiency.

The organization of BIPM and OIML announced the theme of 2022 World Metrology Day is Metrology in Digital Era.

In this context, General Measure combines digital technologies into the practical applications of industrial weighing to bring convenience to customers.

1. Weighing transmitter GMT-X1 can be configurated and monitored by a mobile app: Weasy (available for android systems), connecting through Bluetooth. For instance, to save time and energy, we can use Weasy-app to calibrate the GMT-X1 and make sure it works properly. Moreover, when there is something wrong with the connection between PLC and weighing transmitters, we don't need to check the weighing transmitter one by one. Just opening weasy-app to check the parameters compared to PLC, we can easily find out which weighing transmitter is setting an error and simply correct it.

2. ChexGo series checkweighers are embedded with the automatic feedback system, which can send every checked product weight as pulse signals to the packing machine through the IO ports. With the advanced algorithm and automatic control system, the accuracy of each pack's weight will be improved, so as to reduce loss and improve efficiency.

3. General Measure Mini Data Center box can be connected through LAN port or wifi, using the weasy web page to import the data of checkweigher or packing machine to the PC. It can support up to 30 devices at the same time. When the connection failed during uploading,  it will save the progress automatically and reupload the data starting from the disconnected entry if the connection recovers, solving the disconnection problem of uploading data and bringing convenience to data analysis and management.

Inventions with digital technologies facilitate people's work and life. General Measure always strives to innovate industrial weighing technology and manufacture high-quality products to benefit our clients.

Important Core Part of Granular Packing Machine -- Weight Filler from General Measure

 

General Measure was established in 1993 and has focused on weighing packing controllers for over 25 years. Considering the mechanical design can better match the control system, we started to invest in designing and manufacturing the core part of the granular packing machine -- weight filler.

GM specializes in weighing and packing control systems, designing, and manufacturing in-house. So we can fully control the quality of every part of the production and the performance of final products.

General Measure developed 4 different weighing range fillers for free-flowing granules. With a servo motor, the feeding control can auto-adjust fast and accurately. Inner feeders are made of SS304 and the whole machine can be customized to SS304. Due to the module design, it can be installed and disassembled easily. Optional 10-inch color touch screen HMI simplifies the operation for clients.

AF-05K and AF-10K work by means of gravity feeding combined with vibrator feeding, which can reach the accuracy of ±2g. The speed is up to 1200pcs/h. AF-25K and AF-50K are designed for big bag packing. The speed can reach 900pcs/h.

The OFL Troubleshooting for weighing transmitter GMT-P1

 

 

 

In this article, we are going to share the weighing indicator OFL troubleshooting method.

Four main Causes for OFL:

1. Calibration error

2. Load cell install or wiring error

3. Overload or signal output below the zero point

4. Load cell or weighing indicator AD failure

 

 

Demonstrate Equipment: 

1. GMT-P1 weighing transmitter

2. A weighing platform and One 100g weight

3. A Multimeter 

 

Step 1,

First, we consider calibration error resulting in OFL, so we need to recalibrate the indicator. Enter the menu options, open the calibration menu, skip the previous decimal point, the division value, the range settings, to reach the load cell's current millivolt number display interface. If it shows the correct millivolt data, we enter the zero calibration menu, empty the weighing platform. Then, setting the gain calibration, place the weight on the weighing platform, and enter the right weight. The calibration is complete. We can move back to the menu interface to see if it has the proper weight display.

 

Step 2,

Suppose the load cell's current millivolt does not display properly. We can remove the load cell wiring from the GMT-P1’s terminals and use our multimeter to test the voltage between EX+,EX-. If the voltage cannot be measured, the AD part of the indicator has been damaged. If the voltage can be detected, move to step 3.

 

Step 3,

Remove the SIG+ and SIG- ends from the load cell wires, press on the weighing platform, meanwhile use a multimeter to measure the voltage between SIG+ and SIG- to see if the voltage is within a reasonable range (check the corresponding parameters of the load cell)

If the voltage is within the range and there is a change, we can estimate the OFL caused by overload weights or signal output below zero. If it is not within the range, we consider the AD part is damaged.

In this case, please contact your local equipment suppliers for help.

 

Step 4,

If it is not the above 3 problems, check if the loadcell gravity label is consistent with the direction of gravity, and check if the load cell wiring is correct. Or you can replace the load cell to exclude the load cell’s problem. 

 

That's all for OFL troubleshooting for GMT-P1. Don't forget to give us a like and follow us.

Various Applications of General Measure Checkweigher in Different Industries

 

 

 

General Measure ChexGo series checkweigher has a wide weight range from 1g to 60kg by different models. With the stainless steel housing, it can work well in the harsh industrial environment and high hygienic standard environment.

 

Tobacco Pack Case

CW-600G was installed in the production line for the tobacco pack weight check. Ensuring the standard weight of 50g each pack, CW-600G will reject the underweight or overweight packs(±5g).

 

Flour Package Case

CW-600G and CW-1.2K were applied in this case. The stainless steel and FDA-approved belt reach FDA hygienic standards for the food industry.

 

Condom Pack Case

Each pack has 5 condoms each of which weighs 7g, in total around 46g. Checkweigher with the swing arm rejector will reject the pack when it is under 45g or over 47g to make sure each pack has the right number of products.

 

Assuring 100% of product weighing detection under the law and regulation will reduce the customer complaints and protect enterprise fame. Whilst replacing the manpower to lower the cost, ChexGo can help you increase the efficiency of the production line and avoid risks.
