The ClimaVue™40 is a compact all-in-one weather sensor engineered for solar energy applications, including solar resource assessment and plant performance monitoring. Designed to support IEC 61724-1 compliance, it delivers accurate measurements of temperature, humidity, wind, precipitation, pressure, and lightning activity in a single, easy-to-install unit.
Specifications
| Measurements Made | Air temperature, precipitation, relative humidity, and wind direction and speed. |
| Measurement Scan Rate | 1 s |
| Input Supply Voltage | 9 to 15 Vdc |

| Ingress Protection | The ClimaVue 40 is intended for year-round, unattended outdoor use in meteorological and environmental monitoring applications. It tolerates continuous exposure to wind, heavy rain, dust, and solar radiation. When installed properly, the instrument housing provides environmental protection functionally equivalent to an IP65 rating, though no official certification is claimed. This device should not be subjected to high-pressure water streams, submersion in liquid, or corrosive gases. |
