Overview
The WS400-UMB is a compact all-in-one weather sensor with measurement of temperature, relative humidity, air pressure, precipitation intensity, type and quantity. It is part of the WS product family of professional intelligent measuring sensors with a digital interface and an integrated design with ventilated radiation protection for various environmental applications. An external temperature sensor can be connected.
Benefits
- All-in-one housing concept & easy installation
All-in-one housing concept of a compact weather sensor combining several measurement parameters in one housing with only a single cable connection. - Maintenance-free operation
Maintenance free operation as there are no moving parts that can wear out. - Flexible interfaces and telegrams
SDI-12 and RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, and XDR. - Aspirated radiation shield
