Description
From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications.
Supplementary description
WS3000-UMB Smart Weather Sensor for measuring 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. Measurement output can be accessed by the following protocolls: UMB-Binary, UMB-ASCII, SDI-12, MODBUS, NMEA.
Special features
- Aspirated temperature/humidity measurement
- Open communication protocol:
- UMB-ASCII
- UMB-Binary
- SDI-12
- MODBUS
- NMEA
