Electronic sensor for the detection of free water in aviation fuels. The AFGUARD® sensor is qualified for use as an alternative to Chemical Water Detectors (CWD). The AFGUARD® is considered fail-safe and hazardous area (ATEX and IECEx) approved. The sensor system complies with the ISO 13849 standard.
- Qualified to specification EI 1598 2nd Edition
- Accepted by Joint Inspection Group (JIG)
- Recommended by IATA Fuel Quality Pool (IFQP)
- Required in conjunction with EI 1599 Dirt Defence filter elements
- Recommended for use downstream of all filtration technologies to verify filter performance (PerformanceBasedFilterLife™)
Eliminate uncertainties by installing AFGUARD® and be free to choose from the alternative filtration technologies as they become qualified and endorsed by JIG following field trial.

Reduce redundancy and complexity. Increase operational efficiency.
The AFGUARD-ready® symbol indicates the ability of systems to provide a signal transfer between the EI 1598 AFGUARD® sensor and a logic controller. The requirements to receive input from a sensor qualified to EI 1598 are derived from JIG Technical Bulletin No. 110 with regard to alert, alarm and data storage function.
Many international manufacturers already offer AFGUARD-ready®-compatible logic controllers.
