D-TEK Select冷媒检漏仪
D-TEK Select冷媒捡漏仪的核心是红外吸收filtometer。它包含其一端为红外源（或发射源）,另一端为红外能量检测器，两者之间是滤光器的取样单元。与我们见到的可见光相同，红外能量是电磁能谱的一部分。大多数材料吸收的特定波长的红外能量。从吸收谱图可知道材料吸收的特定波长能量。在7.5-14纳米范围所有冷媒有相似的吸收谱图。
红外源（发射源）产生一个包含所有红外谱波长的高强读能量的束流。这个束流通过滤光器。它阻挡除冷媒吸收波长外的所有波长。过滤的红外能量撞击检测器使它发热。当冷媒由内部泵的作用通过取样单元时，某些红外能量被冷媒吸收。这导致达到检测器红外能量。的减小和检测器温度的降低，从而触发D-TEK Select报警。整个过程在几分只一秒内完成。
由于采用了精确特性的滤光器。INFICON的D-TEK Select对所有冷媒敏感，并消除了虚假讯号。此外，由于没有以便加热传感检测器的化学物衰竭问题。仪器的感测器不会受到高冷媒剂量的损伤，也不会随着时间而降低灵敏度。一旦冷媒从单元中消除，检测器的恢复时间是瞬间的。

D-TEK Select refrigerant leak detector
The core D-TEK Select refrigerant leakage detectinginstrument is the infrared absorption filtometer. It containsthe end as the infrared source (or sources), the other end is infrared energy detector, is between the twosampling unit filter. The light we see the same andvisible, infrared energy is a part of the electromagneticspectrum. Infrared energy absorption of specific wavelengths of most materials. From the absorptionspectrum can know the specific wavelength absorption ofenergy materials. In the range of 7.5-14 nm all refrigeranthave similar absorption spectra.
Infrared source (emitter) produce a contains all theinfrared spectrum wavelength high read energy beam.The beam through the filter. It blocks all wavelengthsexcept the refrigerant absorption wavelength of. Filterinfrared energy impact detector make it hot. When actionby internal pump refrigerant through sampling unit, some infrared energy is refrigerant absorption. This leads toreach the detector infrared energy. The decreasing and detector temperature, thereby triggering D-TEK Select alarm. The whole process is completed in a few secondsonly a.
Due to the adoption of the filter precision characteristics.INFICON D-TEK Select is sensitive to all the refrigerant,and eliminate the false signal. In addition, because not to heat sensing detector chemical failure problem. The instrument of the sensor is not affected by the high cold medium dose damage, nor with the time and reducing the sensitivity. If you remove the refrigerant from the unit,recovery time of the detector is instantaneous.
Characteristic.
