Rosemount 4100AM4NRNR Differential Pressure Transmitter

The Rosemount 4100AM4NRNR Differential Pressure Transmitter is an industrial instrument from Emerson’s Rosemount family that converts the pressure difference between two process ports into a usable electrical signal for control and monitoring systems. Built for demanding process environments, it supports integration with Rosemount primary elements and diaphragm-seal configurations commonly used in flow, level, and DP measurement applications. In typical installations, differential pressure is generated across a primary element such as an orifice plate, Venturi, or Annubar, and transmitted to the sensor for accurate downstream processing. As part of the 4100 series, this transmitter is designed to withstand industrial conditions and to work with standard Rosemount accessories and field devices, enabling reliable DP measurement across a range of plant applications. Exact signal output, electrical options, connection types, and material ratings depend on the specific configuration ordered, so it’s essential to reference the model’s official ordering data to confirm compatibility with your control system and environment.
