Rosemount engineers continue to set the standard for temperature measurement using Rosemount 3144P temperature transmitters with ** fieldbus. This transmitter is the best choice for temperature measurement in control / safety applications.
Rosemount 3144P's multi-variable dual sensor input capability allows it to receive input signals from two sensors simultaneously. You can use the Rosemount 3144P for temperature difference, temperature average, or redundant temperature measurements. The transmitter also has enhanced noise immunity. Transmitter and sensor matching maximizes accuracy.
