The following items are included with the PGS-100 Sun Photometer:
The radiometer
The control unit
Connection cables
CD-ROM
Mounting rings
2.1.1 The radiometer
The radiometer contains the optical input system, solid state spectrometer with a CCD detector array, associated electronics and
temperature stabilisation components. It has a white heat shield to reduce heating by direct solar radiation, an alignment aid
for pointing the radiometer at the sun, and sockets for factory maintenance and the cable connection to the control unit. A
drying cartridge is fitted to absorb internal moisture and to prevent internal condensation that would damage the spectrometer
and optical system.
The radiometer is powered by low voltage supplied from the control unit.

2.1.2 The control unit
The control unit is contained in a weatherproof enclosure. It contains power supplies, control circuits for the radiometer
temperature stabilization, interfaces to the radiometer and communication circuitry for a computer to operate the instrument.
2.1.3 Connection cables
Three cables are supplied with the PGS-100.
One is for connection between the radiometer and the control unit.
The second is for the supply of mains AC power to the control unit.
The third is for communication between the control unit and the operating computer.
.
2.1.4 CD-ROM
The CD-ROM disk contains the operating software for the PGS-100 and necessary setup files.
2.1.5 Mounting rings
The radiometer is normally supplied with two mounting rings that are used for fitting it to a Prede sun tracker. These are not
required for fitting to a Kipp & Zonen sun tracker, with the PGS-100 Mounting Kit, and can be discarded.
Note A computer is not part of the PGS-100 delivery.
2.2 Tools required
The tools required to fit the PGS-100 radiometer to a Kipp & Zonen sun tracker are supplied with the PGS-100 Mounting Kit.
2.3 Location and support base
The location requirements are the same as for any instrument designed to be mounted on an automatic sun tracker for the
measurement of direct solar radiation. The radiometer should have an unobstructed view of the sun throughout the complete
solar arc at all times of the year.
The base support for the sun tracker must be rigid and stable and the alignment must be unaffected by weather and environmental
effects. If this is not possible, the sun tracker must be fitted with an active tracking sun sensor to compensate for movements of
the base support.
The field of view and slope angle of the PGS-100 radiometer input optics require that it must be aligned on the axis of the sun
with a pointing accuracy of 0.2 ° or better.
The ambient operating temperature range of the PGS-100 is from -10 °C to +45 °C. For operation over the range from -30 °C to
+45 °C the Low Temperature Option is required. For operation over the range from -10 °C to +60 °C the High Temperature Option
is required. Please note that both options cannot be fitted at the same time.
2.4 Mounting
It is assumed that the PGS-100 radiometer is to be fitted to a Kipp & Zonen automatic sun tracker using the optional PGS-100
Mounting Kit.
2.4.1 Mounting rings
The radiometer is normally supplied with two mounting rings (shown in 2.1.5) that are used for fitting it to a Prede sun tracker.
These are not required for fitting to a Kipp & Zonen sun tracker, with the PGS-100 Mounting Kit, and can be discarded.
2.4.2 PGS-100 mounting kit
The mounting kit comprises two brackets, clamps, and fixings; to be fitted to a side mounting plate of a Kipp & Zonen sun tracker.
Depending upon the sun tracker configuration, a side mounting plate may also be required.
