Overview

The WS310-UMB is a compact all-in-one weather sensor with measurement of temperature, relative humidity, air pressure and radiation (spectral flat Class A, K&Z CMP10). 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. One external temperature or rain sensor is connectable.

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.

Spectrally flat Class A Pyranometer

Aspirated radiation shield
