When you need to keep a tank or vessel at the right level, inaccurate readings can cause overflow, product loss, or unsafe conditions. This problem hurts your bottom line and can create safety risks. The Emerson Rosemount 5408 Level Transmitter - Non-Contacting Radar gives you precise, reliable level data without touching the material, so you can avoid spills and keep operations running smoothly.
Emerson Rosemount 5408 Level Transmitter - Non-Contacting Radar with Emerson
You need a sensor that works in harsh environments and still delivers exact level measurements. This radar transmitter uses microwave technology to measure the distance to the surface of liquids or solids without any contact. It is built for industries that handle chemicals, water, oil, or bulk solids. If you have struggled with fouling, pressure changes, or temperature swings, this device solves those issues and lets you trust every reading.
Key Features
- With Smart Echo Supervision™ technology, Rosemount Non-Contacting Radars automatically track all echoes, including those from obstructions in the vessel, and distinguish them from the real product surface echo. This ensures the true product level is reliably and accurately reported.
- Low 12V dc lift-off voltage
- Immune to intermittent power loss
- Unique PTFE seal design eliminates the need for o-rings
- Model tailored to SIS requirements, certified to IEC 61508 SIL 2
- Solid measurement with unique solids algorithm
- Signal Quality Metrics: Proactively alerts the operator ahead of potential issues such as antenna coating / build-up, enabled preventative maintenance to be scheduled
- Smart Meter Verification: Built-in automatic diagnostic tool ensures transmitter health and integrity without interrupting the process. Provides a simple pass/fail report helping identify and resolve potential issues. May be run on a user-configurable schedule or on demand.
- Smart Proof Test Package: Quick and easy periodic proof-testing with built-in wizards, offering step-by-step guidance, dynamic visualizations, and ability to save or print detailed reports
- Process seal antenna for applications with heavy condensation and aggressive medias. Also available with Tri Clamp connection.
- 3-A certified for hygienic applications
