The weighing module is a multi-channel weighing sensor. The sensors can meet the measurement requirements of different ranges by adjusting the distance between them. Its main function is to obtain the radial pressure of the table, realize the conversion of the local strain of the weighing module to the electrical signal, and then collect and process the electrical signal by using the data acquisition system.
020-34563445The weighing module is installed in accordance with OIML R60, with a compact structure and a low height, using pillars and anti-pulling design.
Maintenance-free, simple installation, electroplating alloy or stainless steel optional, swing bar structure, with automatic reset function.
The weighing module is elastically deformed under the action of external force, so that the resistance strain gauge attached to its surface is also deformed. After the deformation of the resistance strain gauge, the resistance value will change, and then this positive change will be converted into voltage by the corresponding measuring circuit, thus completing the process of converting external force into electrical signal.
Weighing module Taking a typical chemical reaction kettle as an example, three pressure Weighing modules installed at the bottom of the reaction kettle transmit the weight signal of the kettle body to the junction box. Each weighing module signal is connected in parallel in the junction box, and the angle difference can be adjusted according to the load of each weighing module, and the collected weight signal is sent to the weighing end or weight transmitter. The weighing terminal or weight transmitter processes the weight signal into corresponding weight data.
