Wifi Pressure Transmitter

The Rosemount 3051SAL Wireless Level Transmitter is engineered to deliver best-in-class level measurement reliability, eliminating the maintenance headaches associated with wet legs and capillary systems. Designed for the most demanding process environments, this device combines industry-leading pressure sensing technology with the flexibility of WirelessHART® networks. It serves as an ideal upgrade for facilities seeking a robust wifi pressure transmitter solution, offering superior data security, network stability, and ease of installation compared to standard consumer-grade wireless devices. By removing the need for complex wiring, the 3051SAL significantly reduces installation costs while providing real-time process insight.

Key Features & Benefits

Tuned-System™ Assemblies: Utilizing an asymmetrical system with direct mount and remote seal combinations, this technology reduces temperature effects by 10-20% and improves response time by over 80% compared to traditional capillary installations.
WirelessHART® Reliability: Built on the IEC 62591 standard, the self-organizing mesh network ensures >99% data reliability, making it more secure and dependable than a generic wifi pressure transmitter in industrial settings.
Versatile Process Connections: Available with a wide range of flanged, threaded, and hygienic process connections (3-A® and EHEDG certified) to suit various vessel types.
SuperModule™ Platform: Features an all-welded, hermetic design that resists corrosion and vibration, ensuring a 15-year limited warranty and long-term stability.
Advanced Diagnostics: Includes Statistical Process Monitoring (SPM) and Power Module life monitoring to enable predictive maintenance and reduce downtime.

Industry Applications & Technical Specifications

The Rosemount 3051SAL is optimized for critical applications such as tank gauging, distillation columns, and separator vessels where density changes and temperature extremes pose challenges. Its Electronic Remote Sensor (ERS™) capabilities (available in specific configurations) and direct-mount seal systems make it perfect for measuring differential pressure (DP) level on tall vessels without the drift caused by long impulse lines.

Ideal for industries including Oil & Gas, Chemical, and Life Sciences, the transmitter handles process temperatures ranging from -157°F to 770°F (-105°C to 410°C). Whether monitoring reaction vessels in a refinery or hygienic storage tanks in a pharmaceutical plant, the 3051SAL ensures precise control and safety compliance (SIL 2/3 certified), redefining the standard for wireless level instrumentation.
