An Effective Weather Solar Radiation Shield for FREE!
An Effective Weather Sensor Radiation Shield for FREE! --
the saying, 'Garbage In, Garbage out?' It applies to ET Prediction in
a major way! Collecting weather data, in order to reliably predict changes
in your vehicle's performance, must be done accurately, with NO room
for error. You have heard me talk many times about attempting to take
your weather readings in the staging lanes, and how it simply CAN NOT
work! There are many methods being used out there to predict ET. The
ONLY method that is scientific AND precise, is our Horsepower Correction
method. And, in order to keep the computations (OUTPUT) precise, the
air readings (INPUT) must be gathered accurately. This means that temperature
and humidity gauges, or sensors, MUST be shielded from the sun's radiation.
Any exposure to direct or reflected sunlight will cause inaccurate readings.
expensive methods are being used such as powered, fan aspirated shields
to place your sensors inside of. In experimenting with our Professional
Wireless Weather Station, we found that a reliable Solar Radiation Shield
can be made for FREE, that is as effective, if not MORE effective, than
the expensive powered shields. And, without a powered shield, there
are NO wires to run. Cool, huh?
To keep your sensors away from ground humidity, heat from people, generators,
engines, etc., mount them on a length of PVC pipe available at your
home center. Most sensors come with the correct u-bolts for mounting
to plastic pipe. If you are using a wind sensor, such as our Solar Powered
unit, mount it at least 6 feet above your motor home or trailer's roof.
This way the wind sensor can directly sense the correct wind speed.
Trying to measure wind speed at ground level, around motor homes, trailers,
and trees, is impossible. We have seen all types of home made sensor
shields in the pits, varying from Styrofoam ice chests to salad bowls.
The important thing is that air must be able to get IN and OUT of the
shield freely with no restriction, while blocking the sun entirely.
If your sensors are solar powered, then you want daylight (not direct
sun) to be able to reach the solar panel.
that the perfect shield was an empty 1 gallon bleach bottle! Simply
cut off the top of the bottle and turn it upside down. The bottom of
the bottle becomes the roof for your sensor. Cutting out about 1/3 of
the side of the bottle gives the air easy entry and egress and permits
the solar panel to see daylight. Adding a half inch of Styrofoam to
the inside of the roof of the shield makes it even more efficient, as
I have done to mine. Now, most bleach bottles are white, BUT they are
translucent, and that is no good. We must block the sun's radiation
completely and this is easily done by lighting sanding the exterior
of the bottle, priming it, and then painting it white. It MUST be white
to reflect the sun's radiation and reflected heat. Mount the shield
between the sensor and it's pole using the same bolts. That's all there
is to it. In the morning face the open part of the shield away from
the sun. In the afternoon, you'll have to turn the pole about a quarter
to half a turn to keep the sun behind the shield. Our tests, with the
half inch of Styrofoam added to the roof, show that this home made radiation
shield rivals every other device we have seen, regardless of cost!
Simple, Effective, Solar Radiation Shield
-- New High Temp 'Gun-Style' Digital Infrared Thermometer --
We now offer another Digital Infrared Thermometer with Laser Sighting,
Part # IRT4. The new Gun Style unit has a temperature range of
0 to 788 degrees F, has a backlight, an 8:1 Optical Resolution, and
an Auto-Off feature. The introductory price is just $99.95! That
is about what you would pay for a unit WITHOUT laser sighting and with
a lower temperature range. Comparable prices for a unit with these specifications
is at least fifty or sixty dollars more. For specifications, click here.
