3. Thank you for choosing a NIVELCO instrument We are sure that you will be satisfied throughout its use NIVOPRESS HYDROSTATIC LEVEL TRANSMITTER 1 APPLICATION The NIVOPRESS N submersible hydrostatic level transmitters are applicable for the continuous level measurement of clean or chemically faintly contaminated liquids in bored wells open reservoirs or tanks The NC type is recommended for level detection of polluted water The NIVOPRESS is easy to install in already existing tanks and in deep bored wells and is especially recommneded for controlling of submersible pumps The use of the supplemental accessories is recommnended Using the NAW 104 sewage adapter direct contact between the sewage and the diaphragm of the built in pressure sensor can be avoided Versions with built in 4 wire Pt100 temperature sensor are also available The NOK 300 0 Ex types can be used in explosion hazardous environment 2 TECHNICAL DATA PROBE USER S MANUAL Two wire Three wire NPK NEK NZK NMK NPH NZH 0 200 m water head 0 20 m water head Coe WAIST f Ranges head See ordercode 20x h lt 3 mwh 3x 10x gt 3 mwh 0 10 V 0 V lt 80 mV a measured to the power supply NCK NSK NCH Overload allowed versus range 3x Outputl Built in temperature sensor NE NM NS types Pt100 B class 9 30 VDC NPK Ex 12 30 V DC TAi OVDE Max load U U U power supply Rmn m
