NIVOPRESS D, 2-Wire Level Transmitter
NIVOPRESS D, 2-Wire Level Transmitter
The NIVOPRESS D Series is a hydrostatic 2-wire level transmitter that is suitable for pressure and hydrostatic pressure level gauging of ordinary and hazardous gases, fumes, liquids, and masses. Devices can be used for measuring in clean technologies and also for mediums tending to obturation. Intelligent electronics and HART communication provides application possibilities for even the most difficult tasks.
The NIVOPRESS D 2-wire level transmitter from NIVELCO can convert the relative pressure (input signal) into a direct current signal (output signal). The silicone oil (cooking oil on request) transmission fluid transmits the pressure value from the stainless steel diaphragm to the piezoresistive sensor of the transmitter – smart electronics and HART communication feature local and remote programming. The transmitters are available in standard and non-sparking (Ex ia) versions.

NIVOPRESS D 2-Wire Level Transmitter
Due to their design, the NIVOPRESS D front diaphragm level transmitters are particularly suitable for level measuring tasks by measuring pressure at the bottom of the tank. The same design makes it an excellent instrument for food applications such as milk or pastes. The smooth membrane surface and the maximum permissible medium temperature of 257˚F (125˚C) ensure hygienic cleaning in technologies that require regular cleaning and eliminate the risk of clogging. The device can be used for all level measurement tasks with atmospheric pressure above the liquid column.
Level Measurement Using a HART Multidrop Loop
MultiCONT Multichannel Process Controller can handle up to 15 normal HART or up to 4 Ex-proof HART capable NIVELCO transmitters. Digital (HART) information is processed, displayed, and if necessary, transmitted via RS485 to a computer. Remote programming of the transmitters is also possible. Processes can be visualized on computers by using NIVISION.
2-Wire Level Transmitter with Easy Programming Via PC
HART output devices and a UNICOMM SAK−305 HART-USB modems can be connected to a PC via a wire, while using a UNICOMM SAT−504 HART–USB / Bluetooth modem, the transmitters can be connected via Bluetooth. All data measured by the NIVOPRESS D can be displayed on the PC, and the devices can be reprogrammed if required. For a HART modem, a maximum of 15 standard transmitters can be connected. In addition, the EView2 configuration or NIVISION process visualization software can also be used.
