499AOZ-54-VP Rosemount Dissolved Ozone Sensor | Water Treatment

Product Overview

• Oiltech Controls presents the 499AOZ-54-VP, a premium dissolved ozone sensor for industrial water treatment.
• Engineers utilize the 499AOZ-54-VP to monitor ozone concentrations in food processing and purification plants.
• This Rosemount 499 series model features a Variopol (VP6) quick-disconnect fitting for efficient maintenance.
• The 499AOZ-54-VP provides stable measurements in various aqueous solutions across a wide temperature range.

Core Technical Specifications

• Brand: Rosemount (Emerson)
• Model: 499AOZ-54-VP
• Measurement Range: 0 to 3 ppm (mg/L) as O3 for precise ozone detection.
• Linearity: ±5% of reading or ±3 ppb at 77 °F (25 °C) reference.
• Repeatability: ±2% of reading when the process maintains a constant operating temperature.
• Response Time: Reaches 90% of the final reading within 30 to 90 seconds at 25 °C.
• Operating Temperature: 32 to 122 °F (0 to 50 °C) for standard liquid process monitoring.
• Pressure Limits: 0 to 65 psig (101 to 549 kPa abs) for pressurized pipe installations.
• Process Connection: 1-inch male national pipe thread (MNPT) ensures a secure mechanical fit.
• Wetted Materials: Polysulfone, Viton, Teflon, and silicone provide excellent chemical and corrosion resistance.
• Electrolyte Life: Operates for 3 months, though Oiltech Controls recommends monthly electrolyte replacement.
• Cable Length: Supports up to 300 feet (91 meters) for long-distance signal transmission needs.

Installation and Flow Requirements

• Analyzer Compatibility: Connects directly to Rosemount 1056, 1066-DO, 56, and 5081-A transmitter models.
• Electrical Connection: Requires a VP6 interconnecting cable for the quick-disconnect Variopol fitting system.
• Standard Flow Rate: Maintain 1 to 5 gpm (3.8 to 19 L/min) for flow-through applications.
• Open Channel Flow: Requires a minimum velocity of 1 foot per second (0.3 m/sec).
• Low Flow Cell: Operates efficiently between 2 to 5 gph (7.6 to 19 L/hr) for sampling.

Standard Packaging List

• One Rosemount 499AOZ-54-VP Dissolved Ozone Sensor with integrated VP6 connector.
• Three replacement membrane assemblies for routine field servicing and long-term sensor maintenance.
• Three high-quality O-rings to ensure a leak-proof seal during the membrane replacement process.
• One 4 oz (125 mL) bottle of specialized ozone electrolyte solution for immediate commissioning.
• Fast worldwide shipping available via Fedex, UPS, or DHL for urgent project requirements.

Selection Guide and FAQ

• What is the advantage of the VP6 fitting on the 499AOZ-54-VP?
• The VP6 connector allows technicians to replace sensors without replacing or rerunning the entire cable.
• How often should I calibrate the 499AOZ-54-VP sensor?
• Calibrate the sensor whenever you replace the electrolyte or if process readings appear to drift.
• Does the sensor require specific mounting orientations?
• Mount the sensor at least 10 degrees above horizontal to ensure electrolyte stays on the cathode.
• Selection Tip: When should I choose the 499AOZ series over standard oxygen sensors?
• Select this model specifically for ozone disinfection processes where high chemical selectivity is critical.
