Rosemount Inc. is a subsidiary of Emerson Electric Company.Its headquarters is located in Shakopee, Minnesota, where they manufacture measurement instrumentation such as pressure, temperature, level, DP flow, and wireless, as well as analytical and detection instrumentation for gas analysis, liquid analysis, combustion measurement and flame and gas detection.
The DP-cell will indicate the relative difference between the pressure of the vessel (container) and the atmospheric pressure. This signal is often wired to an indicator that reads out locally, or remotely in a control room, and/or as a control (or feedback) signal to a valve, pump, or other control element to maintain a set pressure, or limit ...
The rest of Rosemount became Rosemount Inc. when they were purchased by Emerson in 1976. Bass Sports was in turn purchased by Raichle in 1972, who ended production of the Rosemount boot in favor of their own designs the next year. Ironically, one of the few other side-entry boot designs was the Raichle Fibre Jet (aka Red and Red Hot), another ...
The level measurement can be either continuous or point values. Continuous level sensors measure level within a specified range and determine the exact amount of substance in a certain place, while point-level sensors only indicate whether the substance is above or below the sensing point.
In a typical implementation, the transmitter injects a constant current of 3.5 mA into the wires, with the direction of current determining the digital logic level. The current passes through a termination resistor of about 100 to 120 ohms (matched to the cable's characteristic impedance to reduce reflections) at the receiving end, and then ...
A magnetic level gauge pulled out from inside the valve housing on top of a railway tank car in the United States [1]. A magnetic level gauge is a level gauge based on a float device that can experience floatation in both high and low density fluids.
