Danfoss DGS Series Fixed Leak Detectors

The Danfoss Gas Sensor (DGS) is a state of the art fixed gas detector which can detect a wide range of different gases. The sensors can be used on a standalone basis or integrated into refrigeration control systems or building management systems (BMS).


  • Cost effective detection
  • Stand-alone or integrates into Building Management Systems
  • Quick and easy to install
  • Visual and audible alarm


  • Power Supply: 12/24 V AC/DC ± 20%
  • Power Monitoring: Green LED
  • Visual Alarm: Red LED
  • Audible: Sounder, enabled/disabled
  • Fault Monitoring: Red LED On – Green LED Off
  • Analogue Outputs: 0-5V, 1-5V, 0-10V, 2-10V, 4-20mA
  • Digital Outputs: 1 Relay, 1 Amp/24VDC/120VAC, Selectable Delay: 0,1,5,10min
  • Typical Sensor Life: 5 years
  • Calibration Requirements: Standards generally require annual test or calibration. Semiconductor sensors are non-selective but calibrated to a specific gas
