Szczegółowe wprowadzenie do umiejętności zjonizowania podczerwieni termometr
The infrared thermometer has an ionization chamber. The artificial radioactive element used in the ion chamber - americium 241 (Am241), has an intensity of about microcuries. Under normal circumstances, it is in a balanced state of the electric field. When smoke enters the ionization chamber, the ionization occurs at the right time. , negative ions, disrupt the normal movement of charged particles, and move toward the positive and negative electrodes under the action of the electric field, destroying the balance between the internal and external ionization chambers, and the current and voltage will change. The ion infrared thermometer is a micro-current changing device that senses smoke particles through voltage changes caused by an ionization chamber equivalent to a smoke-sensitive resistor. Then the microscopic manifestation is that the equivalent resistance of the ionization chamber increases, causing the voltage at both ends of the ionization chamber to increase, thereby determining the smoke situation in the air.
The MTi-15 ionizing infrared thermometer uses a trace amount of artificial radioactive material americium 241 inside. Since the thermometer body is covered by a metal shell, radiation will never leak and users can use it with confidence. In addition, its radioactive energy only uses 55% of NIS-09C, so countries that have restrictions on the use of radioactive energy can use it with confidence. Moreover, the foot configuration and output characteristics of this thermometer are interchangeable with other companies' products. The MTi-15 source chip uses low radiation energy, and after appropriately expanding the ionization chamber, the equilibrium voltage becomes more stable in the cleaning moisture, greatly reducing the false alarm rate. The MTi-15 ion infrared thermometer is a thermometer with advanced technology and stable and reliable operation. It is widely used in various fire alarm systems, and its performance is far superior to gas-sensitive resistance fire alarms.
