Timinal Weighing Measurement Solution

      weighing sensor, also known as force sensor, is widely used in industrial, medical, household appliances, fitness equipment and other fields.

      Weighing sensor is an indispensable part of the industrial control and measurement field. It can convert the signal of mass or weight into a electrical or digital signal for further processing and measurement.Weighing sensors, also known as force sensors, are very widely used, including domestic appliances such as medical infusion pumps, microwave ovens and other household appliances, washing machines, fitness equipment, battery manufacturing equipment, etc.

      In the medical infusion pump, weighing sensors are used to detect the force generated by the pressure of the medicinal solution to control the flow rate of the medicinal solution.By weighing sensors, the flow and speed of the drug solution can be accurately controlled to ensure that patients can be treated safely and accurately.

      In home electrical appliances such as microwave ovens, weighing sensors are used in various cooking functions based on the weight control of ingredients.By accurate measurement of weighing sensors, the food can be ensured that the food is properly cooked to provide a comfortable taste and nutritional value.

      In household appliances such as washing machines, weighing sensors are used to measure the weight of the drums in the drum, so as to set the most suitable water level and washing program control.Through the measurement of weighing sensors, water and detergent can be avoided, while ensuring the good washing effect of clothing.

      In fitness and sports equipment, weighing sensors are used to weigh the actual effective load to accurately measure the energy consumed in the exercise.By the measurement of weighing sensors, it can record data consumed during exercise, muscle strength and other data to help fitness enthusiasts formulate more reasonable training plans.

      In battery manufacturing equipment, weighing sensors are used to accurately measure the weight of the battery material to ensure the consistency of the battery performance.Through the precise measurement of weighing sensors, the quality and performance of the battery can meet the standard requirements.

      Today, due to the limitation of the sensor assembly space, the sensor output usually receives the detection and processing of the system motherboard through a longer connection cable.Taking the latest FX29 compressed sensor of Te Connectivity as an example, its connected cable is 40mm, 100mm, or even the maximum length of within 1m.

The FX29 sensor product contains the basic function of the entire sensor in a compact package that is slightly smaller than the pentagram, which can output the unprecedented MV -level analog signal to the external output.

             FX29 sensor principle

However, because the signal cables will inevitably superimize various external interference noise, when reaching the system application main control board card, it is usually necessary to use a special simulation front to filter and signal amplification processing.In order to further simplify the design, the external reference power supply of the AS1412 chip is the same input source as the incentive source of the FX29 sensor.EssenceThe AS1412 output data rate is 10-1.25K times per second. The MCU can read the data conversion results of the ADC through the SCLK and DOUT interfaces for subsequent data processing.

        In general, FX29 with AS1412 scheme is widely applicable to various weighing and measuring application scenarios, especially in terms of weight measurement that has certain restrictions on sensor assembly space.For some special application scenarios and needs, corresponding adjustments and optimizations can also be made according to the specific situation.
