SIGMA 200-08 Automatic tracking solar radiation measurement system
Solar tracking is a technology for orienting a solar collector, reflector, or photovoltaic panel towards the sun. As the sun moves across the sky, a tracking device makes sure that the solar collector automatically follows and maintains the optimum angle to receive the most of the solar radiation. Some solar concentrators hugely benefit from tracking while some others do not. So, the tracking systems can be added with additional cost and certain trade-offs in system design only when it pays off.
The required accuracy of tracking varies with application. For example, concentrators, especially in solar cell applications, require a high degree of accuracy to ensure that the concentrated sunlight is directed precisely to the solar conversion element. Tracking the sun from east in the morning to west in the evening can increase the efficiency of a solar panel up to 45%, according to some manufacturers.
Sigma 200-08 series automatic tracking solar radiation measurement system is an unattended solar
radiation monitoring system, which can accurately observe direct, scattered and total solar radiation at the same time.
It uses the Angle sensor and the four quadrant balance light sensor technology, automatically tracking the sun, the sun rays remaining vertical to the radiation sensor within the cone of light.Track motion trajectory tracking system according to the sun and light way, the combination of 2D automatic control, realize a full automatic real-time tracking of the sun. Products from the base, bench, screw, gear box, motor, microcomputer controller, direct radiation sensor,scattered and total solar radiation, power and other parts.

Sigma300-10 Visibility sensor
The forward scatter measurement principle and unique design ensure the output is both accurate and reliable
in all weather conditions and will not be influenced by local lights sources, even those that flash. With a standard measurement range of 10m to 10km the sensor is suitable for use in road and aviation constructed from robust aluminium and finished with a high quality powder coat, the sensor will provide years of reliable service. Heating of the optical windows and sensor hoods is provided as standard allowing use in the harshest of conditions. Both optical windows are monitored for contamination and the visibility output is automatically compensated to reduce maintenance requirement.
Forward Scatter Visibility Principle of Operation:
A forward scatter visibility sensor measures atmospheric visibility by analyzing the forward scattering of light by particles in the air.
The sensor emits a light beam and then measures how much the beam is scattered as it interacts with suspended particles in the atmosphere.
FEATURES
* The Forward scatter sensors are optimized for accurate and reliable visibility measurements in various weather conditions. Their unique design ensures that the output remains unaffected by local light sources, including flashing lights
* These sensors are robust and can withstand challenging environmental conditions, making them suitable for outdoor applications

Autonomous Rainfall station with alarm
Features
• Robust and lightweight rain gauge
• Programming via keyboard
• Storage in EEPROM
• Compatible with 0.2mm rain gauges
• High brightness visible in low light
• 220Vac or 12-24ac or VDC power supply
• Recessed mounting (dimensions 48x96x105)
Description
The instrument displays the amount of rain expressed in mm, with a resolution of 0.2 and it is highly visible even in conditions of poor visibility. Programming is done via the buttons on the front. The programming settings are:
- Amount of rainfall for the relay to be activated
- Time that can be set for relay activation from the beginning of the rainy event (default 96h) or to reach the set value.
- Time that can be set to reset the system from the end of the event, useful if the expected amount of rain has not been reached.
In addition to displaying the amount of rainfall, this device allows you to set two alarm thresholds and activate the associated relays when exceeding the set threshold. It has a memory so that even in the event of a power outage
the value remains stored and the counting continues.
Various optional accessories are available, i.e. for sending alarm SMS when exceeding the thresholds set at the indoor and outdoor watertight Box and also USB data logger to record data. Custom technical changes can be made.
The Rainfall Station is compatible with all types of rain gauges, with the resolution set to 0.2mm but
it can also be set for other steps, for example also 0.1mm per pulse.
