Temperature Monitoring
Stationary thermometers are of course one way to monitor temperatures, but many temperatures may be monitored at the same time from a remote location with a six position temperature monitor. To do this a data logger with temperature probes may be used to gather data. A great little data logger is the ONSET U12 4 channel data logger. BUT if real time temperature readings are needed the 6 position temperature monitoring station for $75 is what you need.
The
ports for six temperature probes are located around the perimeter of the 6
position switch to facilitate the connections. The six numbers correspond to the location where the probes are
connected. The monitoring station may also be used to monitor sunlight intensity with
addition of the sky
eye. The switch positions could be set up to read like this:
Position 1 1st drum temperature
Position 2 2nd drum temperature
Position 3 3rd drum temperature
Position 4 collector temperature
Position 5 ambient temperature
Position 6 solar flux density
There is a 5mm power jack on the bottom of the
temperature monitor that's used to connect to a DC wall wart adapter. The input
voltage to the monitor may range from 9VDC to 24VDC.
LM 34 Fahrenheit probes are sold separately.
A solar flux device called the SKY EYE is also available.
The 6 position monitoring station may be attached to a wall near an AC outlet
where it's connected to a Wall Wart DC adapter.
The
Wall Wart 9 VDC power adapter is needed to power the 6 position temperature
monitor. It does not come with the purchase of the temperature monitor
alone, but it is FREE with the purchase of the 6 position temperature
monitor + six LM34 temperature probes.
The temperature probes are $10 each. They have 6" wire leads, but
they may be connected to extension cables 50' long. I use common telephone
extension cables to join the probes to the 6 position monitor.
SPECIAL OFFER: Six position temperature monitor + six LM34 Fahrenheit temperature probes + 9 VDC Adapter for .... $135
The
SKY EYE is another useful tool that may be connected to the temperature monitor for measuring sunlight intensity. It was originally
designed to measure the percentage of the maximum sunlight available, but since
this maximum is close to 1 KW/m^2 the sky eye connected to the 6 position
temperature monitor may be used to approximate insolation (solar flux) in
terms of Watts/m^2. it comes with a 0 ', 10', 25' or 50' extension.
