(actual water content as fraction of the water content in saturated oil) = 0 corresponds to water-free oil, while a = 1 indicates saturated oil. aw measurement with the EE381 sensor is based on the outstanding long term stability and resistance to pollution of the E+E HMC capacitive sensing elements series. -
Page 8: Installation
User Manual EE381 Installation Installation Location Select a location that offers optimum measuring conditions. The oil must be able to circulate freely around the sensing element. Mount the sensor directly into the circulating system and not into a reservoir. Installing the Probe directly into the Process When installing a probe directly into the process, there should be a stop valve on both sides of the point of installation. -
