Specifics of ionic infrared thermometer skills
Infrared thermometer has an ionisation chamber, ion chamber with artificial radioactive elements - Americium 241 (Am241), the intensity of about microcurie or so, under normal circumstances in the balance of the electric field, when there is soot into the ionisation chamber, ionisation of the onset of positive and negative ions, disturbing the normal movement of the charged particles in the electric field under the effect of each to the Positive and negative electrode movement, destroying the balance between the surface of the ionisation chamber, the current, the voltage will change. Ion infrared thermometer that is equivalent to the smoke-sensitive resistor through the ionisation chamber resulting in a change in voltage to perceive the smoke particles of the micro-current changes in equipment. Then the microscopic performance of the equivalent resistance of the ionisation chamber to increase the voltage at both ends of the ionisation chamber, thus determining the smoke in the air.
The MTi-15 Ion Infrared Thermometer uses a trace amount of the artificial radioactive substance Americium 241 inside, and because the body of the thermometer is covered by a metal casing, the radiation will never escape and the user can use it with confidence. In addition, only 55% of the NIS-09C's radioactive energy is used, so countries with restrictions on the use of radioactive energy can also use it with confidence. And this thermometer foot equipment and output characteristics and other companies have interchangeability of goods. MTi - 15 source chip selection of low radiation energy, and appropriate expansion of the ionisation chamber, in the cleaning of moisture, the balance of the voltage is more stable, greatly reducing the false alarm rate. MTi - 15 ion type infrared thermometer is a kind of advanced technology, operational stability and reliability of the thermometer, is widely used in a variety of fire alarm system. In the function is far better than the gas-sensitive resistance class fire alarms.
Photoelectric smoke alarms and ion infrared thermometer comparison:
Photoelectric smoke alarm within an optical maze, the device has an infrared tube, no smoke when the infrared receiver tube can not receive infrared emitting tube announced infrared light, when the smoke into the optical maze, after refraction, reflection, receiver tube to receive infrared light, intelligent alarm circuit to determine whether the threshold is beyond the threshold, if it is beyond the announcement of the alarm. Ion smoke alarm on the small smoke particles to sense some active, a variety of smoke can be balanced response; and forward photoelectric smoke alarm on the slightly larger smoke particles sense more active, on the grey smoke, black smoke response poor. When the onset of a raging fire, the air smoke more small particles, and smothered when the air slightly larger smoke particles will be more. If a fire breaks out, there are a lot of fine particles of smoke, ionic smoke alarms will be more than photoelectric smoke alarms first alarm. These two types of smoke alarm moment distance is not large, but the extension of such fires extremely fast, such places advocate the installation of ionic smoke alarms better. Another type of smothering fire after the onset of a lot of slightly larger smoke particles, photoelectric smoke alarms will be more than the ionic smoke alarm first alarm, such places advocate the installation of photoelectric smoke alarms. If you want to combine the benefits of both, you are able to install both types of smoke alarms in places that require them.
Comparison of gas-sensitive infrared thermometers and ionic infrared thermometers:
Fire smoke is a mixture of gas, liquid, solid particles group, with volume, mass, temperature, charge and other physical characteristics. Ionic infrared thermometer is through there is smoke escaping outside the ionisation chamber. Disturbed the normal movement of charged particles, by the current, voltage changes to determine the smoke in the air. And gas-sensitive pyrometer is to explore the composition of certain combustible gases in the air, so in the fire exploration, gas-sensitive pyrometer function is not as good as the ionisation pyrometer. Gas-sensitive pyrometer in the exploration of combustible gases in the air, can effectively explore the gas, liquefied petroleum gas, gas, carbon monoxide and other combustible gases such as trace leakage, more suitable for petroleum, chemical, coal, electric power, metallurgy, electronics and other industrial enterprises, as well as gas plants, liquefied petroleum gas stations, hydrogen stations and other production and storage of combustible gases in the place.
