Automated Smart Enclosure for EM27/SUN

Introduction

KEYTEC's Automated Smart Enclosure for EM27/SUN is a dedicated protective system developed for the outdoor observation requirements of the Bruker EM27/SUN solar spectrometer. Tested under various climatic conditions, the enclosure provides a stable and reliable field operating environment for the spectrometer, while ensuring an unobstructed optical path for direct solar observation at different latitudes.

The enclosure features dynamic response and automatic decision-making capabilities. Based on preset programs, precipitation status, and external sensor data (customizable), it can automatically control the opening and closing of the cover. This improves the efficiency and completeness of solar spectral data acquisition while effectively protecting the spectrometer from rainfall and harsh environmental conditions.

The system adopts a plug-and-play design and can operate with only a stable power supply. The enclosure is equipped with a pull-out electrical cabinet, aviation connectors, external manual control buttons, a monitoring camera, and visualization control software, enabling convenient on-site maintenance, remote monitoring, and unattended operation.

Optional Expansion

According to the user's monitoring requirements, the enclosure can be optionally equipped with a pyranometer and various meteorological sensors. Pyranometer data can be used for spectral data screening and quality assessment. In the COCCON system, atmospheric pressure is an important input parameter for the PROFFAST algorithm; further incorporating temperature and humidity data can improve the accuracy of retrieval results.

Features

• Rapid rainfall protection: the cover closes quickly and automatically once rainfall is detected, ensuring the safety of the spectrometer.

• Open measurement environment: ensures unobstructed direct solar observation for the EM27/SUN at any latitude.

• Customizable enclosure closing conditions: control strategies can be configured for different application scenarios.

• Supports real-time video display and scheduled recording, making it easy to remotely view the spectrometer's operating status.

• Combined with control software, the system enables remote diagnostics, log viewing,

  manual opening/closing control, and control mode configuration.

• Low-maintenance design, suitable for long-term unattended monitoring.

• Equipped with caster wheels and stabilizing rods for easy mobility and single-person deployment.

• Supports integration with multiple external sensors, such as pyranometers and meteorological sensors.

• Adapted to a wide range of temperature and humidity conditions, ensuring stable operation in harsh outdoor environments.

• Supports software customization and secondary development, allowing sensor data to be converted into automatic cover control logic.
