The reaction kettle is a weighing module for a meter quantitative feeding, reaction process control, discharge and other production process control and data management as one of the integrated automation system, the use of firmware to build a high-performance control platform, with stable and reliable operation, simple and practical operation and superior cost performance advantages.
020-34563445Reactor Weighing system is not a simple circuit can be realized, the MCU as the CPU of the system. In the external circuit need display circuit, keyboard input, power supply, communication interface, sensor, alarm. The weighing module is a kind of self-electric and electromechanical conversion sensor, which is made of piezoelectric material, and the surface of the piezoelectric material is charged by the force. After the charge is amplified and transformed by the charge amplifier and measuring circuit, it becomes the electrical output proportional to the external force. Piezoelectric sensors are used to measure forces and transform non-electrical physical quantities.
Reactor Weighing module is also a detection device, can feel the measured information, and can feel the information, according to a certain law to transform into electrical signals or other required form of information output, to meet the information transmission, processing, storage, display, record and control requirements, usually composed of sensitive components and conversion components. The sensitive element refers to the sensor that can directly feel the measured item, and the conversion part refers to the sensor that can convert the output of the sensitive element into an electrical signal suitable for transmission and measurement.
In order to realize the static weighing and measuring of large containers and hoppers in the industrial environment, the measurement module integrates the weighing sensor, load transfer device, limit and anti-overload, etc., and can be easily connected with a variety of mechanical equipment.
Weighing module is based on the traditional resistance strain gauge sensor, combined with modern microelectronics technology and microcomputer technology to add control functions on the basis of weight display function, including weight display, quantitative feeding, unloading, field equipment control, alarm signal display, formula setting and process monitoring functions
