A digital sensing electronic price computing scale

Abstract

The invention relates to a digital sensing electronic price computing scale. The scale comprises a scale body, a digital sensing module, a keyboard and a displayer, wherein the digital sensing module is disposed in the scale body, while the keyboard and the displayer are disposed on the scale body; the digital sensing module includes a sensor equipped with an elastic sensitive element, an analog-to-digital conversion module and a controller. The computer scale is characterized in that the analog-to-digital conversion module and the controller are hermetically sealed in the elastic sensitive element of the sensor. The digital sensing electronic price computing scale in the invention can effectively protect from parameter modification, moisture and electromagnetic interference and has a simple and compact structure, stable capability, high precision and a long service lifetime.

Description

technical field [0001] The invention relates to an electronic scale, in particular to a digital sensor electronic price calculation scale. Background technique [0002] Electronic pricing scales currently on the market usually include a scale body, a sensor for sensing pressure, an analog-to-digital conversion module, a controller, a power supply, a display screen, and a keyboard, etc., wherein the analog-to-digital conversion module and the controller are separately arranged in the scale body. Open the shell of the scale body to modify or reset the parameters of the analog-to-digital conversion module and the controller to achieve the purpose of cheating. This has led to the emergence of many electronic price-computing scales that are short of weight and less than two in the market. Unnecessary losses are caused, and because there is no other shielding outside the scale body, this type of electronic pricing scale, especially its internal analog-to-digital conversion convers...

[0002] Electronic pricing scales currently on the market usually include a scale body, a sensor for sensing pressure, an analog-to-digital conversion module, a controller, a power supply, a display screen, and a keyboard, etc., wherein the analog-to-digital conversion module and the controller are separately arranged in the scale body. Open the shell of the scale body to modify or reset the parameters of the analog-to-digital conversion module and the controller to achieve the purpose of cheating. This has led to the emergence of many electronic price-computing scales that are short of weight and less than two in the market. Unnecessary losses are caused, and because there is no other shielding outside the scale body, this type of electronic pricing scale, especially its internal analog-to-digital conversion conversion module and controller, is vulnerable to external electricity, magnetism, water vapor, etc. Interference, which affects the stability and accuracy of the pricing scale, and the service life is reduced
