The working principle of weighing module and the way of strain gauge bridge assembly, the data acquisition system consists of lower computer hardware and upper computer software, the software adopts LabVIEW programming technology, the weighing module obtains the radial pressure on the tilting table, the strain gauge under the tilting table generates strain due to the force, the lower computer obtains data signals, and through the serial communication module, the lower computer and the upper computer data acquisition system transmit instructions and data and process the collected signals. The information is transmitted to users by the upper computer panel. This system has the functions of data acquisition and processing, real-time data display and storage, post-processing of data and monitoring of working temperature.
020-34563445The anti rollover weighing module adopts imported stainless steel welded sealed sensors with a protection level of IP68, which can be used in various harsh environments and meet the requirements of OIML R60 C3 and NTEP 10000 III L. It has a unique structure and can be easily installed on various tanks. There are three top plate structures (fixed, floating, and semi floating), which can eliminate weighing errors caused by thermal expansion and contraction of tanks. The weighing module is a multi-channel integrated weighing sensor, with multiple sets of sensors installed on the tilting table. By adjusting the spacing between the sensor blocks, different measurement requirements can be met. The main function of the measuring module is to obtain the radial pressure on the table, realize the conversion from local strain of the weighing module block to electrical signal, and then use the data acquisition system to collect and process the electrical signal.
The weighing module adopts weighing sensors, weighing installation plates, brackets, and support bases. The bottom of the weighing installation plate is connected to the main weighing sensor and installed on the bracket. The bracket is connected to the support base through a rotating shaft and is locked and fixed by a locking rod. The locking rod is installed on the limit sleeve, which is set on the top of the support base. One end of the weighing bracket is equipped with an integrated installation plate, which is used to install the weighing sensor. There are mounting holes on the bracket, and one end of the rotating shaft is fixed to the mounting hole bolt through a screw head, while the other end of the rotating shaft is connected to the bearing on the support base for rotation. The bottom of the limit sleeve is equipped with a rotatable threaded sleeve, and the end of the threaded sleeve is equipped with a driven gear. One end of the adjusting rod is equipped with an adjusting handle, and the other end of the adjusting rod is equipped with an active gear, which is connected to the driven gear for gear transmission. There is a transmission screw inside the threaded sleeve, and the transmission screw is connected to the internal threaded screw of the threaded sleeve for transmission. One end of the transmission screw is connected to the locking rod.
