Need to Increase Batch Consistency and Uptime?

Advanced Hygienic Pressure Transmitters may be the right solution.

If yours is a pharmaceutical or food and beverage application, you know well the need for accurate pressure transmitters. Inherent in these types of batch processes, however, are several points at which traditional transmitters fail. High pressure and extreme heat can cause data errors, leading to issues running the gamut from compromised personnel safety to complete batch loss or even falling out of compliance with US Food and Drug Administration standards. You’re familiar with how often legacy instruments must be recalibrated between clean-in-place (CIP) and sterilization-in-place (SIP) cycles—and with the fact that there’s no way to determine how soon after thermocycling a traditional pressure transmitter has recovered. How many times can the CIP and SIP cycles be run before the transmitter is no longer transmitting accurate readings? Can you really trust the critical pressure data during ensuing batches?

What your operation needs is sound batch-to-batch repeatability so there’s less downtime between batches with increased batch consistency. You are looking for a pressure transmitter that requires less maintenance and fewer calibrations while adhering to industry standards. Of course, safety is a vital factor, but saving money is top of mind, too.

But what if there is a hygienic pressure transmitter that not only could withstand extreme thermocycling temperatures and pressures, but also required fewer recalibrations? Today, Emerson’s Rosemount™ 3051HT Hygienic Pressure Transmitter can offer your operation that level of efficiency and confidence.



Commissioning and routine maintenance operations are simplified with the Rosemount 3051HT Pressure Transmitter’s Local Operator Interface’s built-in configuration buttons and uncomplicated menus.



Detect electrical loop integrity problems from moisture, corrosion, or power supply failure before they force downtime with the Rosemount 3051HT Pressure Transmitter’s Loop Integrity Diagnostic feature.




The Rosemount 3051HT Hygienic Pressure Transmitter was designed and engineered with sanitary fittings that are easy to install, and it has been tested in the harshest conditions in a wide variety of industries. It meets 3-A Sanitary Standards along with American Society of Mechanical Engineers: Bioprocessing Equipment (ASME BPE) and European , Engineering and Design Group (EHEDG) industry standards. It features 32 µ-in. Ra mechanically polished and 15 µ-in. Ra electropolished wetted surfaces. Its stainless steel design is free of voids or crevices to ensure easy cleaning and wipe downs, and its advanced diagnostics work to prevent on-scale failures. With demonstrated top performance, it can tolerate washdown cycles up to 302°F (150°C) for long-term performance and durability. It recovers 20 to 30 times faster than traditional transmitters with minimal drifting. You’ll appreciate its unparalleled seven-year stability which reduces calibration frequency—because you’ve experienced devices that can drift out of specification in just a few months while consuming cash and risking regulatory non-compliance.

Need more motivation? The Rosemount 3051HT’s sensor technology provides outstanding batch repeatability up to ±0.02% Upper Range Limit for 60 batches. Rest easier with the knowledge that it’s SIL 2/3 certified to IEC 61508 (via third-party) and can be purchased with a prior-use certificate of FMEDA data for safety installations.

Why keep guessing when you can be certain? With a five-year limited warranty, these cutting-edge hygienic pressure instruments provides an excellent solution and can offer significant time, cost and safety savings.
