Hydrostatic Borehole Transmitter - NIVELCO - #1

NIVOPRESS N submersible hydrostatic level transmitter consists of a special breathing cable (containing capillary tube and stress resistant inlet) and a probe. There are two different designs of the stainless steel probe: with ceramic

flush diaphragm and stainless steel diaphragm behind a

plastic protection cap.

The level metering is based on the measuring of the

pressure difference between the hydrostatic pressure of the liquid head over the diaphragm and the actual atmospheric

pressure. This pressure difference is converted into

4 ... 20 mA current in the 2-wire version and 0 ... 10 V DC voltage in the 4 - wire version.

Easy installation and wiring is ensured by the use of the

complete set of accessories.

For outdoor measurements the application of over voltage

protection (OVP) is suggested.

To ease installation the use of terminal box (with or without

OVP) is recommended serving as terminal for the wires and for the breathing tube.

NIVOPRESS NPK-200 hydrostatic level transmitters are applicable to clean liquids in bore holes and is especially recommended for monitoring and controlling submersible pumps.

NIVOPRESS NCK-200 type units with ceramic flush diaphragm are for level measurement of tanks and reservoirs and also suitable for contaminated liquids.
