NIPRESS DD-300 Differential Pressure Transmitter

Brand: Nivelco Process Control Co.

NIPRESS DD-300 series differential pressure transmitters with stainless steel sensor and two pressure ports can be used in either 2- and 3-wire systems. 

DD-300 series can be pressurized on both sides with fluids or gases. The differential pressure transmitter measures the difference between the positive and negative side and converts it into a proportional voltage and current output. 

Due to its compact size, it can be installed also in tight spaces. The DD-300 family has various measuring ranges between 0 – 16 bar (0 – 232 psig). 

Transmitters can be delivered with plug-in display UNICONT PLK-501 enabling on-site reading. Ex version is also available
