EASZ-1
The EASZ-1 is a hazardous area approved online monitor that measures the amount of water in any oil or
hydrocarbon under pressure. It is a 2-wire loop powered system that can be calibrated using RS-232 or RS-485.
Operating Principle:
Oil and water are completely different chemically and are characterized by a fundamental difference in their
dielectric constants. The EASZ-1 can easily measure a small or large change in water content due to this
difference. A standard range EASZ-1 can measure water content accurately in a range of 0-25%. The high range
version from 0-50% (80%) or from 80-100% depending on the oil type.
The following graph shows the relationship between water content in oil and the change in capacitance for
different oils in a range of 0-25% water.
