Rosemount 3051ST Pressure Transmitters

Rosemount 3051S In-line Pressure Transmitters have compact design, which enables direct connection between a process and the transmitter. This helps speed-up the installation process, and thus making it easier and cost-effective. These transmitters are the industry leaders for Absolute and Gage pressure measurements.
