描述

20kg 直桿式稱重傳感器

20kg 直桿式稱重傳感器（有時稱為應變儀）可以將高達20kg的壓力（力）轉換為電信號。每個稱重傳感器都能夠測量電阻，該電阻根據施加到桿上的應變（例如壓力或力）並與之成比例而變化。使用該量規，您將能夠分辨出物體的重量，物體的重量是否隨時間變化，或者僅需要通過測量施加在表面上的應變或載荷來檢測物體的存在。

20kg 直桿式稱重傳感器 均由鋁合金製成，能夠讀取20kg的重量。這些稱重傳感器具有四個應變計，它們連接在惠斯通電橋構造中。接線上的顏色代碼如下：紅色= E +，綠色= O +，黑色= E-，白色= O-。此外，這些稱重傳感器提供IP66防護等級，並具有兩個M4和兩個M5尺寸的通孔，用於安裝。

Strain Gauge Load Cell – 4 Wires – 20Kg

A strain gauge is a type of electronic sensor used to measure force or strain (big surprise there). They are made of an insulating flexible backing with a metallic foil pattern. The resistance of a strain gauge changes when force is applied and the object is deformed along with the foil and this change will give a different electrical output. However, these thin foils are very delicate and are easy to over-bend.

In this product, the gauge is attached with epoxy to a chunk of strong aluminum. The metal keeps the strain gauge from being damaged, and constrains the amount of movement. Attach one side to a fixed enclosure or ground, using the mounting holes, to keep them from moving. Then apply weight to the other side in the direction indicated on the side, either by gravity (so arrow pointing down) or by pulling (arrow facing up). The output resistance will change with the amount of deflection, and is measured with a precision ADC or Wheatstone bridge.

Strain gauges are useful for projects when you need to measure pressure, force, weight, and tension. Note that this is just the load cell, no ADC or converter is included! Also, like all load cells, the sensor must be calibrated with known weights once installed!
