آشنایی با سنسورهای تعیین ارتفاع مایعات liquid level measurement sensors سنسورها به جای حواس چند گانه انسان و گاهی فراتر و پیشرفته از آن ، در صنعت ، دارای کاربردهای فراوانی هستند و می توانند بر اساس انچه حس می کنند به قسمتهای مختلف سیستم فرمان داده و یا تصمیم سازی کنند .
سنسور های سنجش ارتفاع مایعات در صنایع گوناگون کاربردهای وسیعی دارند از نمونه این سنسورها می توان به سنسورهای هدایتی و خازنی ، شناور ، تبادل گرمایی ، القایی ، فتو الکتریک ، فشاری و.
.
.
می توان اشاره کرد .
سنسور هدایتی و خازنی : این نوع از سنسورها به صورت پیوسته و یا به صورت نقطه ای ارتفاع را اندازه گیری می کنند نحوه اندازه گیری آنها بر اساس میزان امپدانس بین دو الکترود در مایع و یا بین یک الکترود و دیواره تانک که هادی الکتریسیته است استوار می باشد .
سنسورهای شناور : در این دسته از سنسورها یک قسمت شناور بر روی سطح مایع قرار می گیرد این قسمت شناور به یک کلید مغناطیسی و یا مکانیکی در خارج از مخزن متصل است با تغییر ارتفاع مایع سیستم مکانیکی عمل نموده و یک کلید را قطع و یا وصل می کند.
سنسور های تبادل گرمایی : این نوع از سنسورها از یک سیستم گرماده که معمولا به صورت سیم می باشد و یک ترموکوپل یا ترمیستور تشکیل شده نحوه عملکرد این سنسور به این صورت است که قمستی از المنت در داخل مایع قرار گرفته و بقیه آن در خارج از مایع است .
مقاومت المنت با تغییر حرارت تغییر می یابد ، بنابراین با تغییر ارتفاع مایع و اندازه گیری تغییر مقاومت المنت ارتفاع مایع اندازه گیری می شود .
سنسورهای القایی : این نوع از سنسورها برای فلزات مایع و یا مایعات هادی جریان الکتریسیته به کار برده می شود در این نوع از طراحی یک سیم پیچ اطراف حلقه ای از مایع قرار می گیرد.
اندوکتانس این کویل بر اثر تغییر ارتفاع مایع در داخل تیوب تغییر می کند در یک طراحی دیگر یک هسته دو قسمتی که یک قسمت آن سیم پیچی شده و قسمت دیگر توسط مایع احاطه می شود، مورد استفاده قرار می گیرد .
مقاومت موثر سیم پیچ به طور معکوس به ارتفاع مایع در داخل تیوب وابسته است .
سنسورهای فتو الکتریک : این سنسورها بر اساس ارسال و یا بازتاب نور عمل می کند در حالت ارسال ، یک سیستم که شامل منبع نور و یک فتو دیتکتور می باشد در دو طرف مخزن نصب می شود .

The Easiest and Fastest Way to Learn Japanese
Did you know that about 122 million people in Japan, and another 8 million worldwide speak Japanese? For Americans, it’s perceived as a difficult language to learn, but in fact, it’s quite regular. Once you get the basics down, you’ll be surprised how quickly you’re able to begin speaking it. And even knowing a little bit of the language will make travel to Japan far easier, and much more fun. Whether your goal is to travel, communicate with friends or colleagues, reconnect with family, or just understand more of what’s going on in the world around you, learning to speak Japanese will expand your horizons and immeasurably enrich your life.

The best part is that it doesn’t have to be difficult or take years to master. Thirty minutes a day is all it takes. Because Pimsleur courses are available in MP3 format, you can learn whenever and wherever it’s convenient for you. But it’s not just portable; we get you speaking right from the first day. Pimsleur courses use a scientifically-proven method that puts you in control of your learning. If you’ve tried other language learning methods but found they simply didn’t stick, then you owe it to yourself to give Pimsleur a try.

What’s Included in Japanese Levels 1-4?

- Approximately 2 hours and 45 minutes of culture notes
- In total, approximately 64 hours of audio, all featuring native speakers

What You’ll Learn
This program includes all of Japanese Levels 1, 2, 3 and 4 – 60 hours spoken language practice, culture notes, and reading instruction. With this program you start from zero, first learning survival phrases and vocabulary, and eventually progressing to a high-intermediate level of speaking and understanding Japanese. Every lesson contains an introductory conversation and isolated vocabulary and structures, as well as full practice of all vocabulary introduced. The emphasis is on pronunciation and comprehension to promote proficiency in spoken Japanese. At the completion of this program, you’ll be speaking and understanding Japanese with near-fluency and with impressive conversational skills.

Reading and Writing in Japanese
By the 5th century AD Chinese characters began to be widely used in Japan. This early alphabet, Kanji, created new literacy, but brought many complications in pronunciation. In the 8th century, two new phonetic alphabets, or kana, were devised to bridge the gap: Hiragana and Katakana. Hiragana is used along with the Kanji to show the syllables that form suffixes and particles – “sounds” in other words, while Katakana was used for foreign loan words, like “coffee” or “computer.” Today in Japan, the three writing systems are combined, with Kanji, Hiragana, and Katakana all appearing within a single sentence.

In Japanese 4 you will begin to learn to read the Hiragana alphabet. There are forty-six basic Hiragana syllables, with additional modified syllables that represent voiced and contracted sounds. Japanese is usually written from top to bottom in vertical columns and from right to left.

This course will expand your vocabulary, encourage you to share your opinions and interests, introduce you to less formal conversations, and help you to venture out to new travel destinations in Japan. You’ll learn to share your impressions and opinions, express gratitude, describe people and places, and convey your preferences with characteristic Japanese politeness and grace.

Culture Notes are included at the ends of Levels 1, 2, and 3. Totaling about three hours, these Notes are designed to provide you with background information on the language and insight into Japanese culture.

The Pimsleur Method
We make no secret of what makes this powerful method work so well. Paul Pimsleur spent his career researching and perfecting the precise elements anyone can use to learn a language quickly and easily. Here are a few of his “secrets”:

The Principal of Anticipation
In the nanosecond between a cue and your response, your brain has to work to come up with the right word. Having to do this boosts retention, and cements the word in your mind.

Core Vocabulary
Words, phrases, and sentences are selected for their usefulness in everyday conversation. We don’t overwhelm you with too much, but steadily increase your ability with every lesson.

Graduated Interval Recall
Reminders of new words and structures come up at the exact interval for maximum retention and storage into your long-term memory.

Organic Learning
You work on multiple aspects of the language simultaneously. We integrate grammar, vocabulary, rhythm, melody, and intonation into every lesson, which allows you to experience the language as a living, expressive form of human culture.

Constant Feedback Loop + Build-in Testing
Pimsleur’s unique system of cues and responses provides a constant feedback loop. You can test yourself as you go, and make incremental corrections in creating and refining cohesive, clear responses.

Gives You a Solid Foundation
Each lesson and Level builds on the ones before it and in turn sets the framework for the lessons and Levels that follow. Learn what you need to prosper and to build a foundation to future learning.

The Japanese Language
Japanese has many “registers” or levels of politeness. Throughout every level of your Pimsleur course, you will learn how to speak at a polite register, which is appropriate in virtually any situation you are likely to encounter in Japan.
