Product Introduction

The ML-02 sensor is made for light measurements in industrial environments. The compact dimensions of the sensor body make it easy to integrate within any application. Due to its low weight and low profile the sensor can be easily attached to any light receiving surface. The Mono-Silicon detector with UV resistant diffuser give a cosine response also at low solar elevation angles. Besides the effects of soiling or water deposition on top of the diffusor will be minimized due to the cone shape geometry. The sensor can be used on drones, UAV’s, balloon sonds, renewable industry where efficient energy supply systems will be integrated to building facades, automotive and wearables. Built a cost effective PV rooftop monitoring system in combination with the ML-02, M-box (Modbus®) and PT-100 temperature sensor. We provide different mounting options to easily integrate the sensor. The ML-02 detector with high analog output and can be combined with our industrial interfaces MC-11, MC-20, A-box and M-box. The sensor has 2 years warranty and calibration compliant to the international standards defined by ISO9847.
