DR3413 Success Story: From Measurement Errors to Zero Failures in 30 Days

What Our SCADA Didn’t Tell Us About the Dead-Leg Problem

During a routine night shift, our hydraulic press began cycling slower than usual. The pressure gauge showed normal readings, but every part coming off the line was out of spec. Initially, we suspected a pump issue or control valve malfunction. However, after a thorough investigation, we discovered the root cause: threaded pressure taps used for monitoring had created dead-legs in the sanitary piping. These dead-legs formed pockets where product residue accumulated, baked onto the walls, and became inaccessible to Clean-in-Place (CIP) systems. Consequently, this led to measurement errors and contamination risks, costing us approximately $15,000 in scrapped product and downtime in just one month.

Contrast: Why Threaded Taps Fail Where Flush Diaphragms Succeed

The engineering principle behind the failure is straightforward: threaded pressure taps extend into the process stream, creating stagnant zones where fluid cannot circulate. In sanitary applications, these dead-legs violate hygienic design standards because they trap product and bacteria. Moreover, during CIP cycles, the cleaning solution cannot reach these pockets, leaving residue that compromises future batches. In contrast, a flush diaphragm pressure transmitter mounts directly flush with the pipe wall, eliminating any crevices. As a result, the process fluid flows smoothly, and cleaning solutions can fully contact all surfaces. This design is critical for maintaining sterility in biotech and food processing environments.

How DR3413 Solved Our Measurement Errors and Contamination Risks

We replaced the faulty threaded sensors with the DR3413 sanitary pressure transmitter. Its hygienic, flush diaphragm design completely eliminated dead-legs, ensuring a clean and accurate measurement environment. The DR3413 supports both CIP and SIP (Sterilize-in-Place) protocols, so it withstands high-temperature cleaning cycles without damage. Additionally, its stainless steel wetted parts resist corrosion and comply with 3A food-grade standards. On installation day, the difference was immediately apparent: no more concerns about product buildup or contamination. The sensor provided stable, precise readings from the start.

$15,000 in Waste Eliminated: Zero Failures in 30 Days

Within 30 days of installing the DR3413, we achieved zero failures in our critical processes. The accurate pressure measurements allowed tighter process control, reducing variability and scrap. Specifically, we eliminated the $15,000 monthly loss from contaminated parts and downtime. Furthermore, the hygienic design improved our CIP efficiency, cutting cleaning cycle times by 20%. The DR3413’s high accuracy also enhanced product quality, leading to fewer rejected batches. Notably, the sensor’s robust construction required no recalibration during the first month, saving additional maintenance costs.
