temperature sensor<\/strong> is a device designed to measure and control temperature in various systems and processes. In the context of heating systems, temperature sensors play a key role in maintaining optimal temperature conditions and equipment operating efficiency.<\/p>\n

Installation locations:<\/h3>\n
    \n
  1. Indoors<\/strong> - to control air temperature and regulate heating.<\/li>\n
  2. On pipelines<\/strong> \u2014 for measuring the temperature of the coolant (water, antifreeze) in the heating system.<\/li>\n
  3. In boilers and boilers<\/strong> \u2014 for monitoring and controlling the heating temperature.<\/li>\n
  4. On the street<\/strong> \u2014 in weather-compensated automation systems for measuring outside temperature.<\/li>\n<\/ol>\n

    Types of temperature sensors:<\/h3>\n
      \n
    1. Thermistors (RTD)<\/strong> - change resistance depending on temperature. The most common types: Pt100, Pt1000.<\/li>\n
    2. Thermocouple<\/strong> - create electrical voltage depending on temperature. Popular types: K, J, T.<\/li>\n
    3. Semiconductor sensors<\/strong> \u2014 use the properties of semiconductor materials to measure temperature.<\/li>\n
    4. Infrared sensors (pyrometers)<\/strong> \u2014 measure temperature at a distance by registering infrared radiation from an object.<\/li>\n
    5. Bimetallic sensors<\/strong> - they use two metals with different coefficients of thermal expansion, which causes the plate to bend when the temperature changes.<\/li>\n<\/ol>\n

      Execution options:<\/h3>\n
        \n
      1. Immersion sensors<\/strong> \u2014 installed inside pipelines or tanks for direct contact with the coolant.<\/li>\n
      2. Surface sensors<\/strong> \u2014 attached to the surface of pipes or equipment to measure temperature without contact with the liquid.<\/li>\n
      3. Outdoor sensors<\/strong> \u2014 placed outside buildings to measure outside temperature in weather-dependent automation systems.<\/li>\n
      4. Cable sensors<\/strong> - flexible and thin, can be used for wrapping around pipes or other objects.<\/li>\n
      5. Wireless sensors<\/strong> \u2014 transmit data over a radio channel, convenient for use in hard-to-reach places or for integration into smart home systems.<\/li>\n<\/ol>\n
