General Description

The PWS100 is a laser-based sensor that measures precipitation and visibility by accurately determining the size and velocity of water droplets in the air. It can be used in weather stations in road, airport, and marine applications. The PWS100 uses advanced measurement techniques and algorithms to calculate individual precipitation particle type.

The PWS100 Present Weather Sensor is a laser-based sensor capable of determining precipitation and visibility parameters for automatic weather stations including road, marine and airport stations. Due to its advanced measurement technique and fuzzy logic algorithms, the PWS100 can determine individual precipitation particle type from accurate size and velocity measurements and the structure of the received signal. Auxiliary measurements of temperature and relative humidity (RH) provide improved particle classification.

The PWS100 consists of a Digital Signal Processor (DSP) housing unit connected to a sensor arm that contains one laser head and two sensor heads. Each sensor head is 20° off axis to the laser unit axis—one in the horizontal plane and the other in the vertical plane. The PWS100 ships with a mounting bracket that attaches the DSP housing to a mast or pole.

The PWC100 is a customer field calibration validation device for the PWS100. It simulates particle and visibility data for the PWS100, allowing verification of the calibration constants held within the system. The PWC100 is available as an accessory for the PWS100.
