How do thermocouple sensors work?
A pair of thermocouple is a specific measurement tool designed to measure the body temperature of various equipment and its internal components and a variety of materials. A pair of heat is made of two strands of wires made of two different metals. When these two wires are connected to each other, they form a circuit. This circuit creates two separate electrical connections. One of the connections is formed where the temperature must be measured. This section is called a hot connection or measurement connection. This is one of the most important parts.
Influencing factors in the final price of thermocouple
- کیفیت و نوع متریال یا مواد اولیه ای در سنسور بسیار حائز اهمیت است.
- ضمانت و خدمات پس از فروش
- میزان دقت بابت اندازه گیری دما
- میزان پایداری و ثبات دماسنج
- دامنه یا محدوده اندازه گیری سنسور دما یا محدوده دمایی که توسط سنسور قابل پشتیبانی است.
The types of thermocouples in terms of appearance
Wired thermocouple
Cable heat pair, or wired temperature sensor, is one of the most commonly used products (temperature probe). It is best to use the cable phrase for this type of thermal or heat electronic equipment. The important question is whether the heat pair used in it is the length of the length or compensation? For example, we have three cables for the Type K heating measuring device. KX, KCA and WX Type Cable. The WX task is clear, because of the lower purity percentage, the maximum thermocouple temperature should be 800 degrees Celsius. Also, cutting cables for 1x2x0.50 mm size is better than 15 meters and even less.
Ceramic thermocouple
The ceramic thermocouple sensor falls into the category of high temperature sensors. The C610 and C799 ceramic protective sheath is made in accordance with the German DIN standard. In fact, it can be said that the ceramic sheath is a gold -groove of the temperature measuring temperature -based, metal -based metal and noble metal. ) Type K we want to put the temperature in international standards up to 1260 degrees Celsius in the ceramic protective sheath. We can also use the Ker 610 ceramic sheath to build a S -type thermal pair that we intend to measure high temperatures to 1400 ° C. This ceramic sheath has a fragile structure and should be prevented from contacting the fluid and collision of objects.
Where is the thermocouple used?
Thermocouples are used almost wherever temperature is needed to be measured. But these equipments are mostly used in industrial and scientific purposes. Why is a thermocouple sensor commonly used to measure temperature for various purposes? In the following, we mention 4 main reasons:
- چون قیمت آن ها بسیار مناسب بوده و در سِری های مختلفی ارائه می گردد.
- اندازه گیری دما با آن ها با توجه به اصل کارکردشان، آسان است.
- طیف گسترده ای از رنج دمایی را در محیط های مختلف بدون کوچکترین مشکلی اندازه گیری می کنند.
- سرعت پاسخدهی فوق العاده به تغییرات دما. (اندازه گیری با سیم در معرض یا با یک غلاف محاف)
