เซนเซอร์วัดระดับน้ำแบบไม่สัมผัส Non-contact liquid level sensor XKC-Y25-PNP / XKC-Y25-NPN 5v-12v / 24v 


เซนเซอร์สำหรับวัดระดับน้ำแบบไร้สัมผัส โดยติดตั้งภายนอกถังน้ำความหนาไม่เกิน 20mm รวมกาว (โปรดดูรูปประกอบที่รูปสินค้า) โดยวัสดุต้องเป็นวัสดุไม่ใช่โลหะ ตัวเซนเซอร์จะสามารถวัดระดับน้ำได้โดยไม่ขึ้นกับสเกลปริมาณน้ำ สามารถใช้ได้ทั้งของเหลวที่เป็นกรดเพราะไม่จำเป็นต้องสัมผัส หรือของเหลวอื่น ๆ ที่มีตะกอนแขวง แม้กระทั่งของเหลวที่มีอุณหภูมิเย็นหรือร้อนจนเดือด มีให้เลือก 2 แบบ คือ PNP หรือ NPN  สายยาว ~ 50CM 

กรณีเป็น tank โลหะ กรุณาเจาะเพื่อต่อท่อแยกออกมาปิดฝาและเอาเซนเซอร์ไปจับหลังฝาตามรูปสินค้าได้เลยครับ

Product Description
Intelligent non-contact liquid level sensor/detector (below: water level sensor/detector) which uses advanced signal processing technology and high-speed signal processing chip, the thickness of the container is important for measurement Levels will be less relevant, and high levels of sealed containers, for truly non-contact measurements.

The level sensor (detector) will be installed on the top/bottom of the outer container (high level and low level), it is useless to drill a hole in a non-metallic container, the installation is very simple. 

This measuring level sensor is the most ideal sensor for various toxic substances, strong acids, strong alkalis and various liquids in high pressure sealed containers. There are no special requirements for liquid media and material containers, and are widely used.

Product Features
1: Non-contact liquid level sensor for non-metallic wall
said containers are not in direct contact with liquids,
they are not subject to scaling effects of corrosive acids and alkalis and other corrosive liquids,
or other debris.

2: Intelligent memory function and level adjustment level,
status display level, multi-point serial connection;
support NPN output,  PNP output,  

3: The detection is accurate and stable,
able to detect the level of boiling water

4: Pure structure of electronic circuits, non-mechanical work,
life and stable performance.

5: High stability, high sensitivity, strong interference ability,
no external electromagnetic interference,
there is a special treatment for frequency interference
common mode noise,
compatible with all 5—24 V power adapters in the market.

6: Strong compatibility, can penetrate various non-metal containers,
such as plastic, glass, ceramics and other containers,
the sensing distance can reach more than 10mm; liquid, powder,
particles can be detected.

7: Open collector output, wide voltage range (5 V-12 V) (24 V)
suitable for connecting various circuits and applications.

Technical parameters
Voltage input (InVCC): [DC 5—12 V] [DC24V]
Power consumption: 200 uA
output current; 1—100mA
Response time: 500 mS
Working temperature: 0—100 degrees
Thickness sensing (sensitivity) range: 0—20mm
Humidity: 5%—100%
material container; plastic, glass, ceramic and other containers
Sensor protection: IP67

Operation principle
The detection of the intelligent non-contact liquid level detector is to use the capacity in the water to detect whether there is liquid.

When liquid enters the detector which is static due to the distributed capacitance in the detector.

When the level When increasing the proximity to the detector, the increase in the parasitic capacitance of the liquid
will couple to this static capacity, and finally the capacitance value of the detector will become larger.

This changewill change the ability to convert some signal changes when the IC input capacitance signal converts the signal , and then
A certain algorithm is used to detect and determine the measure of the amount of change when the change exceeds a certain threshold level to reach the sensor point.


Clearance requirements
Between the contact surface of the sensor (or probe) and the outer wall of the container, it  is best to use AB glue or other strong curing glue to stick firmly, if there are special requirements, the gap should be less than 0.5mm, preferably no gap, otherwise it may be Affect measurement accuracy.

Exchange or return policy



Every item comes with a 30-day warranty. However, there are certain conditions that apply:

  1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

  2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

  3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:

  1. Provide a detailed description of the damaged item(s).
  2. Mention any tests or experiments conducted by the customer.

Please note that the store reserves the right to make the final decision regarding product replacement or refund.
