AHHOI IR

IR - Water in-line
The AHHOI System determines the absolute oil humidity by infrared transmitted light technology in lube oils. A determination of water content beneath the specific saturation limit, of free water and of emulsions is possible. It is a low maintenance device and installed in a bypass system. This has no influence to the pipe geometry. For an individually calibration, one fresh oil - and one used oil sample of the installation is necessary. A calibration afterwards is not needed.

Technical Features:

• Measuring range: 0 - 10000 ppm / 0 - 1.0 vol.% water
• Operating voltage: 100 - 240 V AC / 50 - 60 Hz, 24 VDC is available on request
• Pressure – Oil system: 1 - 10 bar,
  pressure – measuring device: 0,8 - 1,5 bar
• Measuring temperature: 0 - 59 °C

Benefit:

• Continuously monitoring of oil sensitive installations (e.g. engines, hydraulic systems)
• Low maintenance cost
• Suitable for new buildings and retrofit
• Reliable through an installed oil filter and pressure valve to detect the measurement chamber

For a failure-free operation a pressure difference of min. 1 bar abs is necessary which could guarantee by a pressure free recirculation. The measurement chamber could clean frequently with the included flush connections.
