Clearing Up Your Queries and Providing Informed Solutions
What is a weighing controller?

A weighing controller is a device that is used to control and manage the weighing process. It is responsible for receiving and processing signals from the load cells or sensors and providing output signals to other devices.

What is a weighing indicator?

A weighing indicator is a device that displays the weight of the load on the weighing scale. It is typically used in conjunction with load cells or sensors to accurately measure the weight of objects.

What is a weighing transmitter?

A weighing transmitter is a device that converts the signal from load cells or sensors into a standardized signal that can be used by other devices, such as a computer or a PLC.

What are load cells?

Load cells are transducers that are used to measure weight. They convert the force exerted by a load into an electrical signal that can be measured and analyzed.

What is calibration?

Calibration is the process of adjusting a weighing system to ensure that it provides accurate and reliable measurements. It involves comparing the system's readings to a known standard and making adjustments as necessary.

Why is calibration important?

Calibration is important to ensure that the weighing system provides accurate and reliable measurements. A poorly calibrated system can lead to incorrect measurements, which can have serious consequences in industries such as healthcare, pharmaceuticals, and food production.

What is zero drift?

Zero drift is a phenomenon in which the zero point of a weighing system shifts over time. This can be caused by changes in temperature, mechanical wear, or other factors.

What is the difference between analogue and digital weighing systems?

Analogue weighing systems use analogue signals to transmit data, while digital weighing systems use digital signals. Digital systems are generally more accurate and reliable, and can provide more advanced features and functionality.

What is the difference between a single point and multi-point weighing system?

A single point weighing system uses a single load cell to measure the weight of an object, while a multi-point weighing system uses multiple load cells. Multi-point systems are typically more accurate and reliable, but also more complex and expensive.

What are the different application of weighing controller?

● Tank / silo weighing ● Process weighing ● Peak weighing ● Batch weighing ● Bagging system, Check weighing ● Loss-in weight ● Weigh feeder ● Continuous weighing and Dosing ● Liquid Filling ● Weighing and Blending

What are the different Models of Weighing Controller?

M02, GMT-P1, GMT-X1, GM7702, GM8804C-2, M04, GM9907, GM8804C-A6, GM8804C-6, GM8804C-7 etc.

How can we select the Weighing Controller model?

Model selection depends on the application, Process flow, Number of Input and output required, Communication protocol requirement, Speed and accuracy requirement.

What types of mounting is available in controller?

Panel mount , DIN Rail Mount , Field Mount

Is there any Touch Screen Model available?

Yes we have 9907 Series weighing controller having touch screen interface.

Is there any TFT display Model available?

Yes we have M04 Series Weighing controller having TFT display.

Is there any VFD Display Model available?

Yes we have a GM8804C series having VFD display.

Is there any model who can control dual hopper application?

Yes we have GM8804CD, M04 D and GM9907LD model who can control dual hopper application.
