ENSOR TILTING
S
RACKET
The Sensor Tilting Bracket (STB) enables you to adjust the position of the solar radiation sensor and/or the UV sensor to match the angle of the sun’s rays. Use the STB with the Energy EnviroMonitor™ to match the angle of the solar radiation sensor to the angle of your solar panels. Use the STB with the Heath EnviroMonitor™ for maximum temperature-humidity-sun-wind index and/or UV readings. Do not use the STB when mounting the solar radiation sensor for use with the GroWeather™. The GroWeather’s ET calculations assume that the solar radiation sensor is mounted horizontally.

Consult the sensor manual for instructions on attaching the sensor to the STB. However, if mounting the sensor on the tilting bracket in a location under 46˚ latitude or in a situation which requires the angle of the tilting bracket to be less than 28˚, you will need to use the standoffs supplied with the tilting bracket as shown below. (The standoffs allow enough room between the bottom of the sensor and the SMA.) The standoffs are made of aluminum; take care not to overtighten when screwing into the bracket. Consult the sensor manual for the remaining instructions on attaching the sensor to the STB.

The instructions below explain how to select the correct tilt angle for the STB and how to mount STB on the Sensor Mounting Arm or on another surface.

The Tilt Angle

The STB allows you to angle the sensors between 0˚ and 66˚, depending on which hole in the STB arms you use when mounting the bracket. The illustra­tion below shows the orientation of the holes (from 1 to 16).
