This manual describes the features and characteristics of the Delta-T Devices Ltd UV3pA, B and AB UV Radiation Sensors, including installation, connection, use and maintenance.
This user manual describes the UV3p family of ultraviolet radiation sensors (UV3pA, UV3pB, UV3pAB) manufactured by Delta‑T Devices. It covers the features, installation steps, wiring diagrams, power requirements, and calibration information needed for accurate solar UV measurements.
The document also includes detailed technical specifications, maintenance procedures, warranty terms, and troubleshooting guidance, making it a complete reference for users and technicians deploying the sensors with Delta‑T data loggers.
| Output | 1 mV per W·m⁻² of radiation |
|---|---|
| UV3pA peak wavelength | 373 nm |
| UV3pB peak wavelength | 313 nm |
| UV3pAB peak wavelength | 360 nm |
| Power supply | 7‑15 V unregulated (~2 mA) |
| Power warm‑up time | 10 seconds |
| Cable length (standard) | 5 m 4‑core screened |
Each sensor provides an output of 1 mV per watt‑meter squared of radiation in its wave band.
The sensors operate from a 7‑15 V unregulated power source drawing about 2 mA.
The sensor requires a warm‑up time of about 10 seconds.
