Submersible probe with integrated 4-20 mA transmitter for hydrostatic level measurement in water and waste water. With capacitive ceramic measuring cell without oil filling and independent measurement range setting via HART interface.
This probe is developed to meet the high demands of industrial and environmental protection. The stainless steel probe body is locked by a capacitive ceramic measuring cell at the bottom and is held by the self-supporting cable on the top. The probe can be suspended e.g. on manhole walls by using a straining clamp.
The non-corrosive enclosure with ingress protection IP68 (NEMA 6X) permits universal use for reliable determination of levels in containers, basins, pump stations and tanks.
The extensive diaphragm has proven as very reliable, particularly in the sewage environment.
The probe is also available with Ex-approval and therefore can be installed in all explosive surroundings.
Via the HART protocol the measurement range of the probe can be set universally.
This is done via a laptop with the NIVUS Configuration Software and the HART interface converter. The Measurement range is adjustable until 20 m water column.
This enables a low set limit of 20% in relation to the stated measurement range (FSO) of the probe e.g. 0 to 2 m or 4 to 6 m. Utilising the widely used 2-wire technology, the installation costs are very low.
