SEVEN Sensor Solutions is a leading manufacturer of high-quality sensors mainly designed to monitor the performance of PV Plants (Photovoltaic Plant). As a company specialized in sensor manufacturing, SEVEN has successfully expanded into other fields, including meteorological and silo-related applications.
Thanks to its wide range of sensors, SEVEN Sensor has succeeded to reach more than 85 countries worldwide, from Japan to USA, and from Sweden to South Africa.
Environmental Sensors
The main product line of SEVEN Sensor Solutions consists of the Environmental Sensors. These sensors are crucial for monitoring and evaluating key performance indicators used to calculate the Performance Ratio (PR) of a PV plant. Some of the core sensors include:
- Irradiance Sensor
- Back of Module Temperature Sensor
- Ambient Temperature Sensor
- Wind Speed Sensor
- Wind Direction Sensor
- Relative Humidity Sensor
- Soiling Sensor
All these sensors comply with the IEC 61724-1 Standard, ensuring reliable performance monitoring for PV installations.
Meteorological Sensors
For the meteorological applications, SEVEN Sensor Solutions offers Class A Thermopile Pyranometers, with optional Class B and Class C models to suit various budget and accuracy requirements. Additional meteorological sensors include:
- Rain Gauge
- Atmospheric Pressure Sensors
These are commonly used in weather monitoring systems and research applications.
Silo Application Sensors
SEVEN Sensor Solutions also designs and manufactures sensors for silo monitoring. These include:
- Capacitive Level Sensors
- Paddle Level Sensors
These sensors are mainly used for detecting the level of solid materials, such as powders or granules, in silos, tanks, and bunkers.
Flexible Output Options
SEVEN provides a variety of sensor output types to accommodate different application needs. All environmental and meteorological sensors are available with RS485 Modbus RTU Output. In addition, optional analog outputs are available for most of sensors, either 4-20mA or 0-10V.
Comprehensive Documentation & Support
SEVEN offers detailed documentation for each of its sensors, including:
- Technical Datasheets
- User Manuals
- Detailed Modbus Maps (for both input and holding registers)
All Modbus-compatible sensors from SEVEN are SunSpec compliant. Customers can access and download this documentation—including calibration certificates for purchased sensors— from the download page.
SEVEN Sensor Solutions’ environmental and specialized sensors are known for their high accuracy, reliability, and ease of installation and configuration. With a “plug-and-play” approach, SEVEN helps end users achieve efficient and seamless integration into their systems.
