Description

Rosemount™ 1408H Level Transmitter – Non-Contacting Radar

Hygienic Radar Precision For Food Industry Control

The Rosemount™ 1408H Non‑Contacting Radar Level Transmitter defines a new standard for hygienic level measurement across the food and beverage industry. Utilizing Smart Echo Supervision™ technology, it continuously and intelligently differentiates product surface echoes from vessel reflections, guaranteeing stable and highly accurate data even in compact tanks or intricate geometries. Constructed with 316L polished stainless‑steel housing, fully resistant to corrosion and contamination, the device ensures long‑term reliability within sanitary environments. Its detection system offers accuracy of ± 0.08 in (± 2 mm) and a measurement range up to 32.8 ft (10 m), perfectly suited to liquids, slurries, or foams. The streamlined body simplifies installation under space constraints while maintaining consistent, repeatable readings unaffected by density, viscosity, or temperature. Designed for ultimate process confidence, the 1408H safeguards product quality from preparation through packaging.

Globally Certified Compliance For Hygienic Applications

The Rosemount 1408H carries an extensive list of hygienic and safety certifications, including 3‑A®, FDA, EC 1935/2004, and EHEDG, which together assure compliance with every major global regulatory framework. These approvals make it fully deployable in dairy, beverage, pharmaceutical, and food mixing environments without additional validation. The IP69K‑rated enclosure guarantees full resistance to high‑pressure washdowns and external cleaning routines. Supporting CIP (Clean‑in‑Place) and SIP (Sterilize‑in‑Place) procedures, the transmitter’s seamless surfaces eliminate niches where bacteria can accumulate. Its smooth, drip‑off seal design prevents moisture retention and condensation artifacts that could distort measurements. Combined, these features ensure continuous compliance with hygienic norms while maintaining durability in aggressive sterilization and sanitation cycles required by international food processing standards.

Advanced Connectivity Enabling Smart Factory Integration

This radar transmitter merges precision sensing with advanced communication flexibility for streamlined integration into both legacy and digital processing networks. It supports 2‑wire 4‑20 mA HART®, 3‑wire 4‑20 mA, and IO‑Link interfaces, enabling direct connectivity with modern controllers running EtherNet/IP, Profinet, Modbus TCP/IP, and OPC UA protocols. Engineers can configure the transmitter remotely or via local M12 connectors for plug‑and‑play installation. Its configurable switch output conveniently indicates abnormal level conditions or cleaning cycle initiation, simplifying alarm management in automated plants. This level of interoperability means that the Rosemount 1408H integrates effortlessly into new digital infrastructures or conventional analog systems, eliminating adaptation complexity. It equips factories pursuing Industry 4.0 readiness with the foundation for predictive analytics, process traceability, and intelligent reporting functionality.

Precision Applications In Food And Beverage Plants

The Rosemount 1408H delivers exceptional accuracy and repeatability across numerous food and beverage applications. In dairy and yogurt production, it ensures hygienic level monitoring in pasteurization vessels and fermentation tanks, unaffected by foam or agitation. Within soft‑drink bottling facilities, the transmitter tracks syrup blending and carbonation lines where high‑speed filling demands instantaneous level response. Breweries benefit from reliable hop‑extract management and fermentation oversight, maintaining product uniformity batch after batch. In pharmaceutical and nutraceutical manufacturing, its sanitary certification allows precise measurement of buffer solutions, purified water, and liquid ingredients. Sauce and condiment producers employ the 1408H during heating and mixing stages, where viscosity changes often compromise legacy sensors. These targeted applications demonstrate the transmitter’s versatility across sanitary, complex, and space‑limited plant scenarios.

Smart Echo Supervision™ Guaranteeing Authentic Surface Detection

Central to the Rosemount 1408H’s success is the embedded Smart Echo Supervision™ algorithm, developed by Emerson for real‑time discrimination of genuine product level signals. The radar continuously monitors all reflective patterns in the vessel, filtering out false echoes caused by agitators, probe rods, or lid irregularities. As a result, the transmitter consistently traces the actual fluid interface even during turbulence or foaming. In parallel, Fast Sweep Technology maintains continuous surface tracking, achieving seamless measurement in rapid filling or draining processes. This integrated intelligence eliminates manual calibration cycles and improves safety by preventing overflow or dry‑run conditions. Process engineers benefit from confidence that every reading represents true product data, making the 1408H indispensable for validated operations requiring unbroken accuracy and traceable performance assurance.

Compact Stainless Design With CIP/SIP Endurance

The transmitter’s compact stainless‑steel form factor and fully polished wetted components promote easy installation in confined hygienic tanks or piping systems. Compatible Tri‑Clamp, DIN 11851, and Varivent® connections ensure universal fit with standard sanitary sealing accessories. The transmitter’s structural integrity withstands continuous exposure to cleaning chemicals, high‑temperature sterilization up to 302 °F (150 °C), and pressure conditions of 116 psi (8 bar). A unique CIP algorithm automatically detects cleaning sequences, temporarily pauses level measurement, and resumes original calibration once rinsing concludes—minimizing sensor wear while maintaining consistent output. The robust construction supports maintenance‑free operation, unaffected by process conditions such as density variation, condensation, or pH shifts. This synergy of smart design and material quality transforms the 1408H into an enduring, maintenance‑free radar measurement solution for sanitary environments.
