What is a 1-inch thread stainless steel float level switch used for?
This float switch is mainly used for liquid level detection and automatic control in tanks, reservoirs, industrial containers, water treatment systems, and pump control systems. It can be used for: Pump control Overflow protection Dry-run protection Alarm systems Automatic liquid level monitoring The 1-inch threaded design provides stronger installation stability and is suitable for larger tanks or industrial equipment.
浮控开关由什么材料制成?
The float ball and float body are made of SU304 stainless steel, offering: Excellent corrosion resistance High mechanical strength High temperature resistance Long service life For more demanding environments, 316 stainless steel customization is also available.
是常开(NO)还是常闭(NC)?
根据浮子的方向,它支持常开(NO)和常闭(NC)。通过将浮子反转 180°,可改变开关逻辑。下开式(默认) ① 当液位上升时,浮子远离干簧管位置,开关断开。当液位下降时,浮球回到干簧管位置,开关打开。上开式 ① 当液位上升时,浮球回到干簧管位置,开关接通。当液位下降时,浮球远离干簧管位置,开关断开。注 出厂默认值通常为下开式,用户可根据控制要求进行调整。.
浮控开关能否直接控制泵或电磁阀?
No. Because the internal reed switch carries only a small current, it should not directly control high-power loads such as: Water pumps Solenoid valves AC contactors Large alarms Recommended solution: Solenoid valves or alarms → use a small relay Water pumps → use relay + AC contactor Direct connection may burn the reed contacts.
有哪些典型的技术规格?
Typical specifications include: Max Contact Rating: 10VA / 50VA Max Switching Voltage: 100V AC/DC or 220V AC/DC Max Switching Current: 0.5A / 1.5A Max Breakdown Voltage: 110V AC/DC or 300V AC/DC Temperature Rating: -30°C to +120°C Actual specifications may vary depending on the selected model.
1 英寸螺纹设计的优势是什么?
Compared with smaller threaded models, the 1-inch thread design provides: Stronger installation stability Better sealing performance Higher mechanical strength Better suitability for large tanks Easier compatibility with industrial pipelines This makes it suitable for industrial liquid level control applications.
杆的长度和螺纹尺寸可以定制吗?
Yes. ELECALL supports: Rod length customization Thread size customization Float quantity customization Cable length customization OEM / ODM production Non-standard customization is supported for different installation requirements.
浮控开关适用于哪些液体?
Suitable for: Water Light oil Cooling liquid Industrial liquids Chemical media compatible with stainless steel Not recommended for: Heavy sludge Liquids with large floating debris Because floating objects may affect switching stability.
买家在购买前应确认哪些事项?
