VT9 is a solar radiation sensor that can be applied for most common solar radiation observations. The scientific name of this instrument is pyranometer. VT9 pyranometer complies with the ISO 9060 second class specifications and the WMO guide. VT19 is a high accuracy hand-held read-out unit / datalogger. The portable VT9 - VT19 combination is well suited for mobile measurements and short term datalogging. VT9 measures the solar radiation received by a plane surface from a 180^o field of view angle. This quantity, expressed in W/m² , is called “hemispherical” solar radiation. VT9 pyranometer can be employed outdoors under the sun, as well as indoors with lamp-based solar simulators. Its orientation depends on the application and may be horizontal, tilted (for plane of array radiation) or inverted (for reflected radiation). VT19 is used to display the measured radiation and for datalogging. Once programmed with the sensitivity of VT9, the display will read the actual value of the solar radiation in W/m². Programming VT19 is done through its PC interface. The system is delivered in a practical transport case, for easy transport and protection during field measurement campaigns. The case also includes the necessary software, AA-type batteries and a USB cable. Batteries allow for approximately 50 days of operation. VT19 may also be used with other pyranometers and heat flux sensors.

Operation:

• Operation of VT9-VT19 is easy
• As VT19 has already been programmed at the factory, read-out of VT9 can be done by switching on the VT19.
• Logging options should be set by connecting the VT19 to a PC.

Delivery:

• VT9 / VT19 / 2 spare batteries (AA) / USB cable / software / transport case

Suggested US:

• Short-term field measurement of solar radiation
• Amplification of pyranometer signals
• Education in solar energy

Product description:

We specialize in offering a wide array of Sunshine Pyrometer that is a meteorological class instrument and has built-in heater, designed for long-term outdoor exposure. We have developed it as an affordable alternative to shade-ring pyrometers, potentiometers and traditional sunshine recorders. Further, this system is easy to use and requires no routine adjustment or polar alignment and can work at any latitude. It is effectively integrated with an internal heater, which keeps the dome clear of dew, ice and snow down to -20° C (in still air conditions), thereby assuring reliable readings in the most toughest climatic conditions.

Specifications:

Global (Total) and Diffuse irradiation in W.m-2

WMO sunshine threshold: 120 W.m-2 direct beam

No moving parts, shade rings or motorized tracking

protected by patents EP 1012633 and US 6417500

No routine adjustment or polar alignment

Works at any latitude

Precision ground glass dome

Direct and Diffuse Radiation:

To accurately measure the direct and diffuse components of incident solar radiation, it uses a range of seven miniature thermopile sensors and a computer-generated shading pattern Besides, it can compute direct radiation by subtracting the diffuse from the global (total) radiation

Sunshine Duration:

The WMO threshold for bright sunshine is 120 W.m-2 in a plane perpendicular to the direct solar beam

The SPN1 uses an algorithm based on the ratio of direct to diffuse radiation It is combined with the absolute values to effectively estimate sunshine duration within a few percent of the WMO standard Requires neither adjustment or reposition to track the sun, which is a distinct advantage over devices with shadow rings No complex electro-mechanical assemblies and no burnt paper tracks to interpret

Outputs and Logging:

It provides 2 analogue voltage outputs for global and diffuse radiation A digital output for sunshine duration can be effectively connected to data loggers like Delta-T DL2e and Gp1 Accurate readings can also be obtained directly from the RS-232 port

Following are its application areas:

Air pollution studies

Cloud cover research

ET and heat flux studies

Canopy analysis

Building energy management systems

PV (photo-voltaic) efficiency monitoring
