Solar MEMS - Model ISS-TX - Digital Sensor for Solar Trackers
From Solar Tracking - Sun Sensors and Control Systems
ISS-TX sun sensor measures the incident angle of a sun ray in both orthogonal axes and the solar radiation. The high sensitivity reached is based on the geometrical dimensions of the design. Its characteristics make it a suitable tool for high accurate sun-tracking, with low power consumption and high reliability. ISS-TX sun sensor has been designed with a unique and novel own technology based on MEMS fabrication processes to achieve high integrated sensing structures at low cost.
Characteristics:
- Two accuracy axes.
- Field of view from 10º to 120º (depending on the model).
- Accuracy from 0.005º to 0.06º (depending on the model).
- It measures direct normal radiation (DNI).
- Communication interface MODBUS RTU over RS-485.
- Dimensions about 80x80x27 mm.
- Useful in renewable energy, specifically on solar trackers.
