The piezoelectric ceramic transducer inside the sensor emits high-frequency ultrasonic pulses that travel downward through the air. Upon encountering a liquid surface (where acoustic impedance changes abruptly), most of the sound waves are reflected back to the sensor. The system accurately calculates the time difference (ToF) of the sound wave&#8217;s round trip through a built-in microprocessor, which is then converted into the liquid level distance.\n        <\/li>\n        <li style=\"margin-bottom: 1em;\">\n            <strong>\u52a8\u6001\u6e29\u5ea6\u8865\u507f\uff1a<\/strong> \u5728\u5b9e\u9645\u5de5\u7a0b\u4e2d\uff0c\u7a7a\u6c14\u4e2d\u7684\u58f0\u901f\u5e76\u4e0d\u662f\u6052\u5b9a\u4e0d\u53d8\u7684\uff0c\u800c\u662f\u968f\u7740\u6e29\u5ea6\u7684\u53d8\u5316\u800c\u5927\u5e45\u6f02\u79fb\uff08\u6e29\u5ea6\u6bcf\u53d8\u5316 1\u00b0C\uff0c\u58f0\u901f\u5927\u7ea6\u53d8\u5316 0.6 \u7c73\/\u79d2\uff09\u3002\u4f18\u79c0\u7684\u5de5\u4e1a\u8d85\u58f0\u6ce2\u4f20\u611f\u5668\u5728\u63a2\u5934\u5185\u96c6\u6210\u4e86\u4e00\u4e2a\u9ad8\u7cbe\u5ea6\u70ed\u654f\u7535\u963b\uff0c\u53ef\u5b9e\u65f6\u8bfb\u53d6\u6c34\u7bb1\u5185\u7684\u73af\u5883\u6e29\u5ea6\u3002\u7136\u540e\uff0c\u5fae\u5904\u7406\u5668\u6267\u884c\u52a8\u6001\u58f0\u901f\u8865\u507f\uff0c\u4ee5\u786e\u4fdd\u6beb\u7c73\u7ea7\u7684\u6d4b\u91cf\u7cbe\u5ea6\uff0c\u5373\u4f7f\u5728\u663c\u591c\u6e29\u5dee\u6781\u5927\u7684\u5ba4\u5916\u73af\u5883\u4e2d\u4e5f\u662f\u5982\u6b64\u3002.\n        <\/li>\n        <li style=\"margin-bottom: 1em;\">\n            <strong>\u51fa\u8272\u7684\u5168\u5a92\u4f53\u517c\u5bb9\u6027<\/strong> Unlike optical sensors (such as infrared or laser) that are easily affected by liquid color, transparency, or water surface reflection, ultrasonic technology is truly &#8220;color-blind&#8221; and &#8220;light-blind.&#8221; This means it is completely unaffected by container transparency, liquid color, or dielectric constant.
