Detailed introduction of ionization infrared thermometer skills
The infrared thermometer has an ionization chamber, and the artificial radioactive element used in the ionization chamber, Am 241 (Am241), has an intensity of about microcuries. Under normal circumstances, it is in equilibrium with an electric field. When smoke enters the ionization chamber, the positive and negative ions generated by ionization disturb the normal movement of charged particles. Under the effect of the electric field, they move towards the positive and negative electrodes respectively, disrupting the balance between the ionization chambers inside and outside, and causing changes in current and voltage. Ionic infrared thermometer is a device that senses the microcurrent changes of smoke particles through voltage changes caused by ionization chambers equivalent to smoke sensitive resistors. Then the microscopic manifestation is that the addition of equivalent resistance to the ionization chamber leads to an increase in voltage at both ends of the chamber, which is used to determine the smoke situation in the air.
The MTi-15 ion infrared thermometer uses trace amounts of artificial radioactive substance americium-241 internally. Because the thermometer body is covered by a metal shell, radiation will never leak and users can use it with confidence. In addition, its radiation energy only uses 55% of NIS-09C, so countries that have restrictions on the use of radiation energy can also use it with confidence. Moreover, the foot equipment and output characteristics of this thermometer are interchangeable with products from other companies. The MTi-15 source chip uses low radiation energy and appropriately expands the ionization chamber, resulting in a more stable balanced voltage during moisture cleaning, greatly reducing false alarm rates. The MTi-15 ion infrared thermometer is an advanced and reliable thermometer, widely used in various fire alarm systems, with functions far superior to gas sensitive resistance fire alarms.
