The CEMS dedicated infrared humidity alarm with built-in pre-filter uses an imported infrared sensor, offering high reliability and high sensitivity. It effectively prevents water ingress into the gas analyzer, providing protection and significantly reducing maintenance costs.
Model
XZ-CGQ-HWH20
When dry (no water present), the infrared light emitted by the infrared LED is reflected by the diamond-shaped mirror to the receiver transistor. At this time, the CE junction of the receiver transistor is fully conducting, outputting a high level. When water is present, the infrared light is refracted by the water, no light reaches the receiver transistor, the CE junction presents high impedance, and the emitter has no output.
