Product Brief:

1151DP3E12 is classic analog differential pressure transmitter of Emerson Rosemount 1151 series. It adopts capacitive sensing principle, realizes differential pressure conversion to standard 4‑20mA current signal, widely applied for measuring tank liquid level, orifice plate flow and process differential pressure of liquid, gas and steam media. Aluminum alloy housing provides reliable environmental adaptability for field installation. This model is EOL discontinued product, mainly used for replacement and maintenance of old‑site instruments. Please confirm measuring range, static pressure requirement and process connection before purchase. Strictly follow instrument specification during installation and calibration.
