目前应用的电子秤,具备“扣除”皮重功能的不多,一般称量为毛重值、其值为货物净重和容器的皮重之和。为获得净重值,需用人计算从毛重值中减去皮重值,给货物的称量代来不便。在模拟电子秤中,是通过调零电路来实现“扣除”皮重功能。近年随着传感器技术和电子技术飞速发展出现了各种类型的高精度数子电子秤。如何实现“扣除”皮重功能?一直是
The current application of electronic scales, with “deduct” tare function is not much, generally weighed as gross value, the value of the net weight of the goods and the tare of the container. In order to obtain the net weight value, it is inconvenient to calculate the weight of the goods by subtracting the tare value from the gross weight value. In the analog electronic scale, through zeroing circuit to achieve “deduction” tare function. In recent years, with the rapid development of sensor technology and electronic technology there have been various types of high-precision digital electronic scales. How to achieve “deduct” tare function?
