EASZ-1 ONLINE WATER IN OIL MONITORS ADD TO QUALITY CONTROL

The EASZ-1 is the fastest response sensor available and the best choice for continual ppm monitoring

The lubrication system of a paper machine typically consists of an oil tank, circulation pump and separator or purifier. The separator is only able to remove water that is in free form. In addition to the separator or purifier, there is also an air dryer in the reservoir tank to remove humidity from the air in the tanks.

In modern paper machines, there are usually two separate lubrication systems, one in the wet end and one in the dry end. It is not unusual that the client has to remove large amounts of water from the system every week.

EESIFLO’s fast reponse water in oil monitor is a unique product in its ability to measure very wide ranges of water in oil immediately . Moisture or water ranges can be configured by simply changing jumpers on its PCB card. A very common setting is 0-1000ppm or 0-10,000ppm. The unit normally requires a one time calibration which is based on high accurate laboratory methods to ASTM standards.

The risk is that water will come into contact with the machine bearings. The EASZ-1 is a continually monitoring device that gives client information on the flowing oil condition in between sampling periods which can sometimes be quite long. The calibration procedure can be traced to ASTM methods of testing. It also has a built in temperature sensor and built in compensation software for applications where oil temperature might change. Deliveries of the standard EASZ-1 water in oil monitor are normally available ex-stock or 1 week from order to any location in the world.
