Keenso Stainless Steel Liquid Level Float Switch User Manual

1. المقدمة

This manual provides instructions for the installation, operation, and maintenance of the Keenso Stainless Steel Liquid Level Float Switch. This device is designed for reliable liquid level detection in various applications, including water tanks and pools. It features a durable stainless steel construction and is suitable for use in environments with temperatures up to 120°C and pressures up to 5 MPa.

2. انتهى المنتجview

The Keenso Liquid Level Float Switch is a robust sensor designed for accurate liquid level monitoring. Its primary components include a stainless steel body, a floating ball, and electrical wiring for connection. The switch operates by detecting the position of the floating ball, which changes with the liquid level, thereby opening or closing an electrical contact.

الشكل 2.1: Detailed diagram showing the dimensions (e.g., 78mm total length, 28mm float diameter, M10 thread) and key electrical specifications of the float switch. This includes working voltage (0-220V), working current (0.5-1A), material (SUS304 & SUS316), operating temperature (0-120°C), maximum pressure (5 MPa), and maximum power/switching current for low and high voltagالتطبيقات الإلكترونية.

الشكل 2.2: This image provides a close-up of the float switch, detailing its construction. It highlights that the floating ball is made of 304 stainless steel, and the clip spring is 316L material. It also notes the device's ability to operate at temperatures up to 120°C and withstand 5 MPa pressure, making it suitable for various environments. The working voltage range of AC 0-220V and DC 0-200V is also indicated, confirming its compatibility with most power sources.

المميزات الرئيسية:

• تطبيق واسع: Suitable for various liquid level detection tasks in small to medium pressure storage tanks and pools.
• مادة متينة: Constructed from SUS304 and SUS316L stainless steel for corrosion resistance and reliability.
• مقاومة درجات الحرارة العالية: Operates effectively at temperatures up to 120°C.
• High Pressure Resistance: Withstands pressures up to 5 MPa.
• التثبيت المرن: Supports both vertical and horizontal mounting configurations.

4. الإعداد والتثبيت

Proper installation is crucial for the accurate and reliable operation of the float switch. Follow these steps carefully:

1. اختر موقع التركيب: Select a location in your tank or container where the desired liquid level needs to be detected. The switch can be mounted vertically or horizontally. For side installation, ensure the float can move freely.
2. تأمين جهاز التبديل: Use the M10 threaded connection to securely fasten the float switch to the tank wall or a suitable mounting bracket. Ensure a watertight seal if installing through a tank wall.
3. التوصيلات الكهربائية: Connect the two wires from the float switch to your control circuit.
   • The float switch acts as a simple contact closure. When the liquid level changes, the float moves, and the internal reed switch opens or closes.
   • مهم: This floating ball switch cannot directly control high-power devices such as solenoid valves or AC contactors. For such applications, an intermediate small relay must be used to handle the higher current and voltagالمتطلبات.
4. وظيفة الاختبار: Before full deployment, test the switch by manually raising or lowering the liquid level (or simulating it) to ensure the contact changes as expected.

الشكل 4.1: The float switch shown installed in an outdoor setting, likely for irrigation or water management, illustrating a practical application where liquid level monitoring is required.

الشكل 4.2: تفصيلية view of the float switch, emphasizing its design for side installation. This configuration allows for level detection from the side of a tank or reservoir.

5. تعليمات التشغيل

The float switch operates based on the principle of buoyancy. As the liquid level rises or falls, the stainless steel float moves, causing an internal reed switch to activate or deactivate. This change in contact state can then be used to trigger alarms, control pumps, or activate other devices via a relay.

• التشغيل العادي: The switch will maintain its contact state (normally open or normally closed) until the liquid level causes the float to move past its activation point.
• Reversing Contact Operation: To reverse the contact's behavior (e.g., change from normally open to normally closed when the float rises, or vice-versa), you can physically invert the float ball on the stem. This allows for flexibility in setting up high-level or low-level detection.
• نطاق التحكم: The floating ball travel is approximately 10mm, which defines the control range. This allows for two combinations: one for a longer detection range and one for a shorter, more precise range, depending on how the float is positioned.

6. الصيانة

The Keenso Liquid Level Float Switch is designed for minimal maintenance due to its durable stainless steel construction. However, periodic checks are recommended to ensure optimal performance:

• فحص العوائق: Regularly check the float and stem for any debris, scale buildup, or foreign objects that might impede the float's free movement. Clean as necessary.
• التحقق من الأسلاك: Ensure all electrical connections are secure and free from corrosion or damage.
• تحقق من العملية: Periodically test the switch's functionality by manually changing the liquid level or simulating a change to confirm it activates correctly.
• نظافة: If operating in environments with potential for buildup, gently clean the stainless steel components with a non-abrasive cleaner and soft cloth.
