Rosemount 1151 Differential Pressures Transmitter

Rosemount 1151 Differential Pressures Transmitter

The Rosemount 1151 Differential Pressures Transmitter is a transmitter that measures the pressure difference between the two ends of the transmitter, and outputs a standard signal (such as 4~20mA, 0~5V). Differential pressure transmitters are different from ordinary pressure transmitters in that they all have two pressure ports.

Differential pressure transmitters are generally divided into positive pressure terminals and negative pressure terminals. The pressure at the end should be greater than the pressure at the negative pressure section to be measured.
