MODEL 41003

MULTI-PLATE RADIATION SHIELD

INSTRUCTION SHEET 41003-90

REV C012114

INTRODUCTION

The Multi-Plate Radiation Shield protects temperature and
relative humidity sensors from error-producing solar radiation
and precipitation. This shield relies on a combination of plate
geometry, material and natural ventilation to provide effective
shielding.

INSTALLATION

The Multi-Plate Radiation Shield is designed to be mounted on
a relatively at open area. For best performance, the shield
should be placed in a location with the following characteristics:

- Good air circulation around shield.

- Away from large masses (asphalt, masts, solar panels)
especially metal items.

- Away from building exhaust vents, electrical machinery
and motors.

- Away from standing water, water fountains and
sprinklers.

MAINTENANCE

The Multi-Plate Radiation Shield requires no regular maintenance
in normal use. Dirt or dust accumulation on the plates and bracket
can be cleaned with soap and water. Do not use solvents.
