NIVELCO NIPRESS DRD-8 Series User Manual

Thank you for choosing NIVELCO instrument
1. APPLICATION
NIPRESS D–800 series pressure transmitters with stainless steel flush sensor measure pressure and convert it
into voltage and current output can be used in either 2- and 3-wire systems. D-800 consists of robust screw-in
pressure transmitters with excellent performance. Its modular construction provides high flexibility to the user.
Transmitters can be delivered with plug-in display UNICONT PLK–501 enabling on-site reading. Ex or SIL
versions are also available.
