The basic NE comes with either one or two electrodes, depending on whether the user has selected to use the container walls (for conductive containers only) as the reference electrode or has opted to obtain a second immersed electrode to serve as a reference, in this configuration, the user may monitor a single level set point. The Series 300 features protection against fast rising volt- age transients with the use of two surge protection components, one located in the 0.75 inch OD 316 housing of the transducer and one located at the surface, grounded via DIN-rail or ground wire.
product spotlight | Level Focus on level Level indicators determine the position of a liquid surface within a vessel, such as a tank, in order to control inventory or regulate a process. Continuous level monitoring refers to a method in which the device measures level on a constant basis, displaying or transmitting the actual liquid level as it changes. Point-level measurement measures the liquid at speciﬁc points.
