Electronic Water Sensor

 

AFGUARD®

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

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.

Features

  • Constant monitoring of aviation fuel quality

  • Cost-effective (cost savings on CWD)

  • High-precision measurement

  • Maximum accuracy through reliable sensor technology and traceable certified calibrations

  • Energy consumption: Max. 750 mW
  • Maximum operating pressure: 16 bar

AFGUARD-ready®

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.
