Rosemount 3051SAL Liquid Level Transmitter

The Rosemount™ 3051SAL Liquid Level Transmitter System electronically determines differential pressure (DP) with the help of two pressure sensors that are connected with a non-proprietary electrical wire. Designed for applications involving tall vessels and distillation columns, where extended lengths of capillary or impulse piping were historically necessary, this system offers the following benefits:

  • Quicker time response

  • Streamlined installations

  • Limited maintenance

  • More precise and consistent DP measurements


The 3051SAL ERS System has a pressure range of up to 10,000 psia (690 bar) and an ambient temperature limit of -40 to 185 °F (-40 to 85 °C). It features coplanar and in-line sensor module platforms, as well as a selection of process connections. This scalable, 2-wire 4-20mA HART® architecture comes with a 12-year limited warranty.
