PWS100 weather phenomenon sensor

PWS100 is a sensor based on the principle of laser, which accurately measures the visibility of rainfall by accurately measuring the size and speed of raindrops in the atmosphere. It can be used in roads, airports, and maritime weather stations. Advanced measurement techniques and calculation procedures are used to calculate the properties of precipitation particles.


Features:
Can identify many precipitation parameters, including drizzle, rainfall, snow, hail, hail;
Continuous, long-term unattended wilderness;
Compatible with multiple data collectors.



Technical principle:
PWS100 is a weather phenomenon sensor based on the principle of laser to measure precipitation visibility parameters. It can be used in automatic weather stations on roads, maritime and airports. Based on advanced measurement techniques and fuzzy logic algorithms, the PWS100 can detect individual precipitation particle types including precise dimensions, velocity values ​​and received signal structures. The auxiliary measurement function of temperature and relative humidity provides good particle size classification.
PWS100 includes a digital signal processor (DSP) unit connected to the sensor arm, including a laser head and two probes. Each probe is based on a 20° axis offset of the laser unit (one on the horizontal plane and the other on the vertical plane). Equipped with a mounting bracket for connecting the DSP unit to the pole.
