    LEL, Lower Explosion Level (50 mg/l), the oil mist detector will trigger an alarm. GDMS-OMD14 is also capable of detecting water vapour. Due to water vapour, corrosion on major parts inside the engine may occur which will damage the engine.
  • Page 10 User Manual Based on a widely-used principle of light measurement, GDMS-OMD14 does not have the disadvantages of some older OMD systems. The GDMS-OMD14 is a pipe- free system, with sensors mounted directly at the engine wall, it allows quick and exact measurement of oil mist concentration in each engine compartment.
  • Page 11 GDMS-OMD14 ® User Manual Key benefits of the GDMS-OMD14 System 1. The oil mist is measured inside the engine where it develops. Therefore, the response time from the development of oil mist until the system raises an alarm is very short.
