Concept and brand model examples of digital weighing sensors

Intelligent digital weighing sensors are the core of packaging, filling, sorting, and weighing scales. Digital weighing sensor is a new type of electronic weighing technology, which uses highly integrated and intelligent processing units inside the sensor to preprocess the analog weight signal through analog/digital conversion and automatically correspond to the variableLoad CellDigitally compensate for zero point, temperature, nonlinearity, hysteresis, creep, etc., and finally output a digital signal.

The output digital signals are processed by microcomputers and other digital devices. Although this is a simple and effective method, the accuracy of the entire measurement and control system is limited by the accuracy of the A/D converter. A digital weighing sensor is a device that can directly convert the measured analog quantity into a digital output. It can directly interface with a microcomputer or other digital equipment to achieve digital measurement and control.

Compared with analog sensors, digital weighing sensors have the following characteristics: higher measurement accuracy and resolution; Stronger anti-interference ability; Better stability; Digital weighing sensors are easy to interface with microcomputers, facilitate signal processing, and achieve automated measurement and control.

Next, give examples of several brands and models of digital weighing sensors:

1、 German HBM FIT7A Digital Load Cell

FIT7A is a digital weighing sensor used for automatic weighing scales, sorting and packaging equipment. Intelligent weighing sensors are the core of packaging and sorting equipment as well as automatic weighing scales. adoptGerman HBMThe FIT7A digital weighing sensor ensures that your dynamic weighing system can achieve its maximum potential.

FIT7A can be used alone and can control the mechanism without the need for a PLC. A proven filter that can eliminate interference from the conveying device. Free PanelX software that reduces development time and allows for optimization of weighing scales.

2、 German HBM C16i load cell

　　C16i digital weighing sensorMade of stainless steel, with built-in overload protection function, it can quickly compensate for eccentric loads and achieve precise weight under harsh environmental conditions.

Using the digital weighing sensor C16i, it can accurately weigh up to 60 tons of load, with accuracy levels of C3 and C4. High precision and durable, C16i is very suitable for horizontal measurement of track scales, truck scales, and industrial containers.

In order to achieve more reliable data transmission, the weighing data has been directly converted into a stable RS485 signal (4-wire) in the sensor. The use of digital technology greatly simplifies the eccentric load compensation process. The protection level is as high as IP68/IP69K, which is very sturdy and durable. In addition, due to its identical size specifications with the analog weighing sensor C16A, the existing system is very easy to upgrade and replace. The C16i digital weighing terminal WTX110-D is perfectly matched and can form a modern weighing and measuring system, providing excellent data quality for technicians.
