PYS 3428 Dual-Channel Pyrodetector

作为双通道,单元素PyRodetector,Pys 3428(更换到LHI 814)包括两个单个元件,每个元件各自热补偿。每个输出光学链接到50内金属壳体内的单独光学窗口。对于每个窗口,各种窄带光学滤波器可用于满足一系列特定的感测要求。

Almost like two detectors in one housing, the PYS 3428 Pyrodetector includes two sensing elements, each positioned with it’s own optical window. Each element has its own individual output signals, thus the name Dual-Channel. Both elements are thermally compensated by an additional blinded element sitting aside.

由于Pys 3428 PyRodetector专门为气体测量应用设计,因此它配有窄带滤光器窗。bob投注体育信赖吗通常,一个窗口用作参考,我们将过滤器版本G20提供为参考窗口。
