Ambient Temperature Sensor measures the air temperature in the environment where the PVs are placed in degrees Celsius (°C) by using by using a PT1000 probe. This Ambient Temperature Sensor Model is compatible with all Dataloggers and PLCs with RS485 input port. It is supplied with mounting facility, and protected from direct sunlight & radiations by a plastic radiation shield with four aspirated plates that allow the air to pass freely.

This Irradiance Sensor Model’s designation is 3S-2IS. It is specially developed to calculate the Performance Ratio (PR) for the dual orientation PV plants, as it calculates the average irradiance value as per the number of panels in each direction. Installation directions of panels in PV power plants and the number of panels in these directions may be different.

This Irradiance Sensor Model’s designation is 3S-4IS. It is specially developed to calculate the Performance Ratio (PR) for the PV plants with three or four orientations, as it calculates the average irradiance value as per the number of panels in each direction. The user will be able to set the number of panels in each orientation for the correct calculations.

The SEVEN Soiling Sensor is designed to accurately measure energy losses caused by dust, dirt, and other environmental factors on photovoltaic (PV) panels. By monitoring the soiling level, operators can directly see how much production is being lost. For example, if the sensor reports a 10% soiling level, it means the PV system is experiencing a 10% energy loss (PV Soiling = Energy Loss).
The measured soiling data is transmitted to data loggers and receiver units via a 3-wire RS485 bus using the Modbus RTU protocol.
It is a two-axis static ultrasonic anemometer used for accurate measurements of Wind Speed and Direction in all environmental conditions. It is Capable of measuring wind speed up to 85 m/s without giving up.
Heating option is available, for quick defrosting. A model with anodized aluminum alloy case with anti-corrosion coating is available. This feature makes it possible to be used the instrument even in particularly aggressive environments. The anemometer meets the requirements of MIL-STD-810G Method 509.6 (salt spray corrosion test). High immunity to electromagnetic interference makes it suitable for measurements in electrically noisy environments.
The SEVEN 3S-WS Wind Speed Sensor is a professional anemometer designed for accurate measurement of horizontal wind speed in environmental and industrial applications, particularly PV power plants. The sensor converts wind speed into an electrical signal in meters per second (m/s) using a cup-star anemometer with a reed switch or optional Modbus RTU/4–20 mA outputs.
Built for durability, the sensor features seawater-resistant anodized aluminum or UV-resistant ASA housings, making it suitable for harsh outdoor conditions. Optional heated models prevent icing, ensuring reliable performance in cold climates. The sensor can easily connect to SEVEN Irradiance Sensors, Sensor Boxes, and compatible data loggers.
