The technical development trend of data multihead weigher and data measurement verification instrument panel has gradually become a new favorite in the field of weighing technology. It has been outstanding in the industry for its advantages of simple adjustment, high efficiency, and strong ability to work on the spot. Previously, Shouqin enterprises used digital and analog sensors, and electronic truck scales and static data rail scales have already been upgraded to digital multihead weighers. There is a microcontroller inside the data multihead weigher, which can diagnose itself. Each one has its own detailed address. The instrument panel can monitor the output of each sensor online and carry out intelligent solutions, which not only further improves the feasibility of the weighing equipment. It is reliable, and can easily handle some regulations that are difficult to be completed by analog sensors, such as large tare weight and small weighing, wheel weight inspection, etc.
Coupled with its unique high-precision high-speed A/D conversion technology, comprehensive sensor data compensation technology and remote control high-speed explosion-proof communication capabilities, the characteristics exceed the limit of analog sensors. The precision of OIMLC6 is achieved. Compared with the characteristics of the data multihead weigher and the simulation sensor, the following characteristics of the data multihead weigher can better consider the process management regulations 1 High reliability, strong anti-interference, good lightning protection characteristics 2 The simulation sensor is connected by the instrument panel For the power supply system, the encouraged working voltage of the bridge circuit is equivalent to the power supply system of the external instrument panel. On the spot of industrial production, the instrument panel and the sensor are easily affected by weak electricity and surge damage, which will lead to unstable data and information, and even damage the sensor instantly.
3. The digital sensor adopts the technology of sealed stainless steel plate metal laser welding machine, and it is filled with helium gas to maintain the reliable operation of the internal power supply circuit, and the waterproof level is IP68. Various maintenance power supply circuits and anti-shock design schemes have been improved. The switching power supply displayed on the instrument panel is first solved, and then the voltage regulator tube is used for the encouragement of the bridge circuit, which eliminates the waves from the switching power supply and lightning strikes. Influenced by the surge, the sensor outputs a stable data signal, which ensures that the sensor is working normally. 4 The data weighing equipment in continuous work can ensure the continuity of production. During continuous work, the instrument panel not only detects the working conditions of each digital sensor at all times, but also can detect the common failure of a certain sensor. Automatically start the continuous working mode, which can still ensure the weighing under a certain precision for a certain period of time, and will not cause the production and manufacturing to shut down.
In addition, the instrument panel will send a signal to the customer to accurately locate the common fault sensors and require replacement. 5 Simulation of the sensor system software Once the sensor has a common fault, it cannot be weighed, which will lead to a major event of shutdown and production shutdown.
