Lufft WS3000-UMB Reference Weather Sensor with redundant pressure module
Product Number: 8390.U02Overview
The WS3000-UMB Weather Sensor with redundant pressure sensor is a Climate Reference Sensors in a high quality aluminum housing fullfilling WMO and aviation standards. it is typically used by meteorology services, in AWOS applications and as reference for calibration verification of Air Temperature, Relative Humidity, and Air Pressure.
Relative humidity is measured by means of a heated capacitive sensor element; a precision PT100 measuring element is used to measure air temperature. A resonant pressure transducer is employed for precise pressure measurement.
The sensor is delivered with a DAKKS ( ISO/IEC 1702) calibration sheet. All technical parameters are given for the full operating range.
The robust and high precise Climate Reference Sensor WS3000 is designed for professional meteorological applications in all climate zones. It delivers highly reliable data, even in extreme ambient conditions.
The weather sensor is designed to replace single sensors in a meteorological weather station.
Examples of use:
Weather stations from meteorological serives
Calibration / Verification of Air Temperature, Relative Humidity, Air Pressure
Aviation weather (AWOS Systems) - redundant pressure measurement included
Climate meteorological weather station
Hydro-meteorological reference station
