GALC Series Gas Detectors

Industrial Application

The GALC line of industrial gas detectors delivers maximum flexibility and reliability in the most demanding industrial settings. It features a selection of ATEX-certified fixed point detectors (Zone 1 and Zone 0 configurations available) for combustible, toxic and refrigerant gases, as well as Oxygen level monitoring.

Choose from our list of available specifications and optimize your GALC detector for low initial investment or build an intelligent solution that reduces installation and maintenance costs.

The consistent performance of the GALC is ensured by its self-diagnostic function, which constantly monitors the condition of the sensor and signal lines. The IP66 flameproof aluminum enclosure and stainless steel sensor head make for stability and durability in harsh operating environments. The large, high-visibility OLED display allows for at-a-glance status identification and provides access to advanced onboard configuration features.

The one-person, TouchCal™ calibration procedure of GALC detectors is incredibly simple and is performed non-intrusively, via magnetic key. This eliminates the need for hot work or system downtime. Solderless sensor replacement and pre-calibrated sensor options available.

Benefits:

Maximum safety: The GALC is compliant with relevant EU standards (ATEX, EN 50270). The IP66-rated, explosion-proof aluminum enclosure along with the stainless steel, corrosion-resistant sensor housing and cable glands make it a perfect solution for the most demanding industrial environments.

Universal compatibility: Select between 4-20mA current, Modbus RTU, or relay/transistor outputs and choose from our wide range of available gasses for versatile integration of the GALC into existing systems or upcoming projects. Whatever the requirements, the GALC is the one-stop solution for industrial gas detection.

Modular customization: maximize the value of your system. Configure the GALC for low initial investment or build an intelligent solution to minimize downtime and streamline maintenance for substantial savings. Benefit from our best-in-class TouchCal™ non-intrusive calibration feature (stock for all GALC units) and explore our low-maintenance sensor configurations, solderless sensor replacement feature and pre-calibrated sensor options.
