Product Data Sheet PS-001316, Rev. B April 2013 Micro Motion® Model 7950 and Model 7951 Signal Converters Micro Motion® Model 7950 and Model 7951 signal converters are the perfect complement to Micro Motion gas and liquid density and viscosity meters. These devices convert the meter output signals into accurate process measurements. Because they are easy to use, you can quickly set up and configure the signal converters to meet your individual process needs. Receives inputs from Micro Motion gas density, specific gravity, liquid density, and liquid viscosity meters Provides high accuracy readings of density, specific gravity, viscosity, and process variables Outputs readings in multiple formats such as kg/m3, g/cm3, °API, °Brix, and % concentration Easy-to-use, four-line, backlit configurable display Wide-ranging I/O capabilities, with the option to increase the quantity of inputs/outputs available Supports wide application range, including interface detection, fuel density, and quality control Wall-mount signal converter Panel-mount signal converter

Micro Motion® Model 7950 and Model 7951 Signal Converters The Micro Motion® Model 7950 and Model 7951 signal converters has been specifically designed to operate with the Micro Motion gas density, specific gravity, liquid density, and viscosity meters. These signal converters are powerful tools that convert live input values from density and viscosity meters into usable process variables. Installation flexibility. The 7950/7951 signal converter accepts inputs from Micro Motion gas density, liquid density, and viscosity meters. Additionally, it can accept inputs from other meters and...
