浆水池设置高低位液位传感器,实时监控收集池内液位

在浆水池中设置高低位液位传感器,特别是采用雷达液位传感器,是一种高效且可靠的解决方案,旨在实时监控池内液位,并自动控制浆水输送泵的启停,从而确保系统的稳定运行并防止潜在的问题如池水外溢或泵体空转受损。以下是对该方案的一些详细分析和优势说明:

 雷达液位传感器的优势




非接触测量:雷达液位传感器通过发射微波信号并接收其回波来测量液位,无需与介质直接接触,因此能够有效避免液位探头因长期浸泡在浆水中而遭受的腐蚀和浆水附着问题。

高精度测量:雷达液位传感器具有较高的测量精度,能够准确反映池内液位的变化,为自动控制系统提供可靠的数据支持。

长寿命与稳定性:由于是非接触式测量,传感器不易受到介质物理特性的影响,因此具有较长的使用寿命和较高的稳定性。

实时监控与显示:人机界面(HMI)是操作人员与系统交互的窗口。在这里,操作人员可以直观地看到当前液位高度,并根据实际生产需要调整高低液位阈值。当液位达到或超过设定的阈值时,HMI界面会提供清晰的视觉提示。

安装维护简便:传感器安装在搅拌池顶部,远离浆水直接接触区域,使得安装和维护工作更加简便快捷。同时,雷达液位传感器通常设计有易于拆卸的结构,便于进行定期检查和维护。

灵活可调:高低液位阈值可根据实际需要任意调整,以适应不同的生产场景和需求。

报警与保护功能:除了基本的自动控制功能外,系统还具备报警与保护功能。一旦检测到异常情况(如液位异常波动、泵体故障等),系统会立即发出报警信号,并可能采取紧急停机等措施以防止事故扩大。

自动控制系统:该系统集成有PLC,负责接收雷达液位传感器发送的信号,并根据预设的逻辑判断来自动控制浆水输送泵的启停。当液位超过高位阈值时,系统自动停止泵的运行以防止池水外溢;当液位降至低位阈值以下时,则自动启动泵以恢复浆水的输送。

How to find ideas to post new article in your blog

How to find ideas to post new article in your blog    阅读原文»   It is true that sometimes being a blogger may face situations where I would personally like to call it your brain juices got dried up as you have pretty much ran out of topic to blog and you are in crisis as your readers are anxiously waiting for your new posts but you are unable to give in. That’s when you will probably come with excuses like I just posted last week although that post was more directly towards the newbies who stop themselves from making money but it’s still pretty much the same even though you consider yourself not a newbie. The fact is that ideas are everywhere and I mean everywhere if you know where to find it and know how to leverage it. You may be surprised that sometimes these ideas are just right in front of you but you are not observant enough to convert these ideas and turn it into your blog post. Today I will share some tips on where to get these ideas and most of it is part of your dai

Over A Year After Android Launch, ShopSavvy Finally Comes To The iPhone

ShopSavvy was one of the best early Android applications. It launched in October of last year after winning one of the initial Android Developer Challenge top prizes (when it was still known as GoCart). But despite the success it has seen on Android, one question remained: When would it be available for the iPhone. Today, it finally is. Developed by the guys at Big In Japan , ShopSavvy is an app that allows you to use your device as a portable barcode scanner. You point your phone's camera at any barcode and it will read it, do a product look up, and give you information about the product, as well as where you can find it online or at nearby stores and for how much. Obviously, something like this is a window shopper's dream. ShopSavvy was one of the best early Android applications.

Lindsay Lohan Breakup Confirmed by Lohan, Locksmith, Police [Gossip Roundup]

Farewell, last season's Suri Cruise fashions. Goodbye, Amy Winehouse's bathing suit. Adieu, humanoid version of Lauren Conrad. And so long, LiLo and SamRon's fairytale romance. Lindsay Lohan confirmed her split with Samantha Ronson and insisted the decision was part of a very healthy and mature effort to " focus on myself ." Upon hearing this, Ronson changed her locks and discussed a restraining order with police, so confident was she in Lohan's ability to turn productively inward. Lohan promptly had a run-in with the police . Who would have imagined such a messy breakup for this model relationship? Courtney Love's lawyer, on her client's drug-fueled plunge into broke-ness: ""Courtney noticed the money was gone when there wasn't any left." Deadpan gallows humor: the only possible response to having Courtney Love as a client. (Besides asking for a hefty retainer.) [ P6 ] Before Lauren Conrad's contract expired in March, MTV
