Introduction
Summary of Features
The UV3p sensors are sensitive to ultra-violet radiation. They are
intended for measurements of solar UV of interest to plant scientists and
people involved in environmental monitoring.
The family of sensors covers different parts of the UV region of the solar
spectrum. The B region has traditionally been associated with the most
biological damage, but there is increasing interest in the biological effects
of the lower energy A band. The AB sensor includes both A and B bands.
The sensors incorporate a photodiode detector and transimpedance
amplifier, powered by a single rail power supply. This produces a
standard millivolt output signal that is suitable for data logging.
The sensor can be supplied with an optional levelling mount.
The UV3p sensors are improved versions of the former UV2p sensors,
with the following features:
•
Millivolt output with preset, standard sensitivity
•
Data logger compatible
•
High stability, low temperature coefficient photodiodes
•
Self cleaning, stay-dry diffuser with water drainage slots
•
Good cosine response with infinity-error correction ring
•
All-aluminium body with weather resistant anodising
•
Individual sensor calibration and spectral response certificates.
Scope of This Manual
This manual contains the specifications and performance of the UV3pA, B
and AB sensors, and describes their installation with Delta-T data loggers.
You may also need to refer to the appropriate Delta-T logger User Manual
