Rugged Rosemount® Analytical rugged Model 3900 sensor features a wide temperature operating range, versatile mounting options, and advanced diagnostics
Emerson Process Management has released the Rosemount® Analytical Model 3900 general purpose pH/ORP sensor, designed to meet the broadest range of applications in the industry. It has the widest temperature operating range of any general purpose sensor and is the first to function at sub-zero temperatures, providing accurate measurements in applications from -10 degrees C to 100 degrees C. Each sensor is equipped for both ¾ inch and 1 inch mounting, allowing it to fit in smaller pipes, giving optimum mounting versatility in insertion, submersion and flow-through applications.
The Model 3900 features the patented AccuGlass™ sensor glass formulation which has been field-proven in premium sensors designed for rugged environments. The AccuGlass formulation exceeds industry standards and resists cracking. In addition, a unique Teflon double-junction reference electrode protects the sensor from poisoning ions. The complete encapsulation of the sensor eliminates leakage or high humidity problems found in other pH/ORP sensors.
The Model 3900 gives the user access to a wider range of more advanced diagnostics. In addition to glass diagnostics, a stainless steel solution ground allows reference diagnostics, simplifying maintenance and scheduling. The solution ground also reduces noise, makes for a highly stable measurement, and makes internal temperature compensation respond more quickly than with previous generation solutions.
The Model 3900 is a combination sensor including pH, ORP (Oxidation Reduction Potential) and temperature within the sensor body. It is designed to measure aqueous solutions in pipelines, open tanks, or ponds. The sensor is compatible with all Rosemount Analytical analyzers as well as those from other manufacturers.
