Explosion Proof PT100 Thermocouple Temperature Sensor



Ⅰ.PT100 thermal resistance integrated temperature transmitter (0-100 °C) with variable transmission 4-20MA output overview:

Flameproof temperature transmitter with display thermal resistance, thermocouple is a new type of temperature measuring instrument, on-site LCD or LED digital display, temperature transmitter second line 4 ~ 20mA. DC signal output, temperature sensing components can be used.The compression spring type anti-vibration structure is adopted, and the temperature sensing element and the upper protection tube adopt a cylindrical explosion-proof structure, and have the characteristics of being able to draw core.

Huaheng Instrument produces and supplies thermal resistance and thermocouple. Our thermocouples are widely used in China and around the world.  Applicable to petroleum, chemical, light industry, electric power and other industries. Air, steam, mist and other media contain explosive mixtures such as hydrocarbons and corrosive places. The measuring range is -200~1000°C. The on-site display is especially suitable for use. Bimetal thermometers and other high temperature media.


PT100 temperature transmitter , its resistance is proportional to the change in temperature. The relationship between the resistance of PT100 and temperature is: when the temperature of PT100 is 0 °C, its resistance is 100 ohms, and its resistance is about 138.5 ohms at 100 °C. Its industrial principle: When the PT100 is at 0 degrees Celsius, its resistance is 100 ohms, and its resistance will increase at a constant rate as the temperature rises. The principle of the action of the thermal resistance is based on the fact that the temperature of the material changes with the change of the temperature when the temperature changes. When there is a temperature gradient in the measured medium, the measured temperature is the range of the temperature sensing element. The average temperature in the internal medium. Ordinary package PT100 thermal resistance / platinum resistance temperature sensor, is a stainless steel tube, the platinum resistance element is packaged inside, lead wire to achieve the purpose of protecting platinum resistance components, for wet, harsh and other environments in need.


Ⅱ .Only fully immersed elements are used to determine product temperature. One of the temperature sensor elements may be installed inside the water level probe.
