Description:

Nivopress NFK / NPK / NBK / NCK level probes are 2-wire 4~20mA submersible transmitters used for the hydrostatic measurement of levels in liquids.
The pressure is converted into an electrical signal.
Applications include: level measurement in wells, boreholes, wastewater plant, vessels, and standing or running water.

Common Accessories for Level Transmitters:
NAA-101 Terminal Box with filter.
Protection: IP65.
Size: 93 x 93mm.
NAA-102 Terminal Box with filter and integral OVP.
As above, with Overvoltage protection:
Voltage clipping: slow - 90 Vpp, fast - 33 Vpp.
Line resistance: 13 ohm.
Max rating: 600 W / 1ms.
NAA-209 Hanging Cable Clamp.
LPN-OVP (Rev 1) DIN Rail mount OVP unit.
For best possible protection in Lightning prone areas, we strongly recommend using OVP protection at both ends of the installation. Our LPN-OVP overvoltage protection device is ideal for this purpose.
