Rosemount Analytical Model 410 VP applicable for wide ranging conductivity measurements in sanitary applications

IRVINE, Calif., June 25, 2008 — Emerson Process Management introduces the Rosemount Analytical Model 410VP four-electrode conductivity sensor, the latest addition to the PUR-Sense family of sensors for the life sciences and food and beverage industries. The wide dynamic range of the sensor (1 uS/cm to 1400 mS/cm), makes it ideal for clean-in-place (CIP) monitoring. 

Instead of two sensors, one to measure the high conductivity cleaning solution and the other to measure the low conductivity rinse water, a single Model 410VP is the first single four-electrode sensor that does the complete CIP conductivity measurement. The result is lower initial cost, less space taken up by sensors and analyzers, and reduced maintenance and training requirements. In addition to CIP monitoring, the sensor can be used to monitor the conductivity of eluents in chromatographic separations and to detect liquid interfaces.

All wetted plastics and elastomers in the Model 410VP sensor are compliant with FDA food contact regulations, and all wetted surfaces except the electrodes have a 16 micro-inch (0.4 micrometer) Ra finish. The sensor is designed to meet 3A and EHEDG hygienic standards, and is available in 1-1/2 inch and 2 inch Tri-Clamp, Varivent N and G-1 ¼ sanitary fittings. A quick disconnect Variopol fitting is standard, making removing the sensor from the process piping easy. The sensor is calibrated at the factory, so startup is fast and easy.

The Model 410VP sensor incorporates a Pt1000 RTD for temperature compensation. The RTD makes contact with the sample through a stainless steel interface, so response to temperature changes is rapid. The sensor is compatible with the Emerson Model 1056 Intelligent analyzer.
