(1) Requirements and installation methods of the tested container The\ntested containers are divided into 3 categories according to their\nmaterials:The first category: insulating material container Containers made of\nnon-metallic materials with flat surface, uniform thickness, compact\nmaterials, and good insulation properties; such as glass, plastic, non-\nabsorbent ceramics, acrylic, rubber and other aterials or their composite\nmaterials. Installation method: 1. If the container wall where the measuring\nprobe is installed is of multi-layer material, the layers should be in close\ncontact with each other without bubbles or gas interlayers. The inner and\nouter surfaces of the container wall should be flat. 2. Wall thickness: 0-20mm\n3. Tank type: spherical tank, horizontal tank, vertical tank, etc. 4. The\ninstallation method of this kind of material container is shown in Figure\n1;The probe can be pasted and fixed with glue or fixed on the outer wall of\nthe container with a non-metal bracket. Try to avoid metal and other parts\nwhere the probe is installed, so as not to affect the detection. The location\nwhere the probe is installed should avoid the liquid inlet and the flow path\nof the liquid. There should be no silt or other debris inside the container\nfacing the low-level probe, so as not to affect the detection; Metal\nconductive material container The second category: metal conductive material\ncontainer Containers made of metal or other conductive materials; such as\nstainless steel, copper, aluminum alloy or materials with electroplated metal\nlayers on the surface. Because capacitive sensors are sensitive to all\nconductive objects, this type of container cannot be directly attached to the\nouter wall of the container; therefore, for containers of this type of\nmaterial, holes need to be made on the side of the container. The installation\nmethod is as follows. installation method Prepare two rubber plugs and the\nnecessary tools for opening threaded holes;Two threaded holes are opened in\nthe high position and the low position respectively, and the hole diameter\nmatches the size of the rubber plug; Put a rubber plug on the threaded hole\nand tighten it to check for water leakage, and add glue to seal if\nnecessary;Paste the sensor on the rubber plug with glue and fix it with the\nbracket. After the glue has solidified, remove the bracket. The installation\nof the metal container is shown in Figure 2. The third category: non-metallic\nmaterials that absorb water Containers made of ceramics, tiles, bricks, tiles,\ncement, wood boards and other materials are insulators or weakly conductive.\nThis kind of container may not be detected when it is close to the liquid\nlevel sensor when it is dry and without water, but when the container is\nfilled with water, the container wall will absorb water, causing the container\nwall to become a conductor; even if the container is empty When the sensor is\nclose to the container wall, the signal will also be detected. If the sensor\nis to be used on a container of this type of material, the installation method\nshould be in accordance with the installation method of a metal container. For\nthe installation method, see \"Class 2: Metal Conductive Material Container\"\nand Figure 2; or use an external pipe to install. External pipes are divided\ninto external non-metallic pipes and external metal pipes . 7 \/ 14 The\ninstallation method of external non-metallic pipes is shown in Figure 3-1 and\nFigure 3-2. The installation method of external metal pipes is shown in Figure\n4-1 and Figure 4-2 Parameter Supply voltage (Vin): (DC 5-12V) (DC 24V) Output\nmode: Switch quantity (Low pulse effective) Power ripple requirements: \u0026lt;=200\nmV Electric current: 5mA Response time: 500mS Working temperature: -20~ 80°C\nHumidity: 5%~100% Induction thickness (Sensitivity) range: \u0026lt;=20mm (Container\nwall thickness) Liquid level accuracy: ±1.5mm Line length：500MM (±10MM) (Bulk\ncan be customized) Terminal sequence：Brown (power supply positive)，yellow\n(signal output) Blue (power negative), Black (COM terminal) Material: PC V0\nFireproof material Waterproof performance: IP67 Figure 5 The sensor is\ninstalled on the iron pipe with the three-prong joint (the installation\ndiagram of metal and water-absorbing container) Figure 6 The sensor is\ndirectly attached to the non-metallic water pipe with a smaller diameter\n(diagram of installation of insulating container) Application environment 1.\nY25-V, Y25-NPN\/PNP (5-12V) It is only applicable under the conditions of good\nEMC environment. For example, the connection with MCU, and some simpler load\napplications, such as LED indicator lights, piezoelectric buzzer, etc. And\nthere is no high-power capacitive and inductive load and harsh electromagnetic\nenvironment on the power bus. 2. Y25-NPN\/PNP (24V), Y25-RS485 (24V) This model\nis carefully designed for harsh industrial environments. Added professional\nEMC components, such as spike absorption, electromagnetic compatibility, and\ntransient suppression and surge protection. It can be directly connected to\nPLC, electromagnetic relay, etc. It has a very strong anti-interference\nability and is suitable for all harsh industrial application environments.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eThe intelligent non-contact liquid level sensor uses advanced signal processing technology and high-speed signal processing chip to break through the influence of the wall thickness of the container and realize the true non-contact detection of the liquid level in the closed container.\u003c\/li\u003e\n         \u003cli\u003eThe liquid level sensor has intelligent liquid level reference adjustment and liquid level memory function, liquid level status display mode, which can realize multi-point series connection; can support high and low level output, NPN, PNP signal output and RS485 communication interface output ;Open collector output mode, wide voltage range (5~24V), suitable for connecting various circuits and product applications(Please Choose the appropriate model for your usage).\u003c\/li\u003e\n         \u003cli\u003eHigh stability, high sensitivity, strong interference capability, free from external electromagnetic interference, special treatment for power frequency interference and common mode interference, to be compatible with all 5~24V power adapters on the market.\u003c\/li\u003e\n         \u003cli\u003eStrong compatibility, through a variety of non-metallic containers, such as plastic, glass, ceramics and other containers, the sensing distance can reach 20mm; liquid, powder, particles can be detected.\u003c\/li\u003e\n         \u003cli\u003eOpen collector output mode, wide voltage range (5~24V), suitable for connecting various circuits and product applications.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n\n\n\n","brand":"Taidacent","offers":[{"title":"Default Title","offer_id":41433435308192,"sku":"B07QKHGFLL","price":147.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0418\/7134\/3776\/products\/B07QKHGFLL.jpg?v=1638521084","url":"https:\/\/dingoship.com.au\/products\/taidacent-non-contact-liquid-level-sensor-contactless-water-level-sensor-externally-attached-liquid-induction-level-switch-water-level-switch-pnp-output-24v-pnp-output-24v-2","provider":"DingoShip AU","version":"1.0","type":"link"}
