Stop Using Current System If You Have DR3425 Micro Differential Sensor

The Hidden Cost of Inaccurate Cleanroom Pressure Monitoring

Our cleanroom was critical to drug development, but the air pressurization between sterile and non-sterile areas was constantly out of spec. The gauge showed a steady 35 Pa, yet contamination levels were increasing daily. This discrepancy cost us $250,000 annually in wasted product and rework. The problem wasn’t just a simple pressure issue; it was about measuring tiny differences that could mean the difference between success and failure in pharmaceutical manufacturing.

What Our Existing DP Sensor Didn’t Tell Us About Cleanroom Pressurization

Cleanroom pressurization requires measurement of tiny pressure differences between spaces to ensure proper containment and prevent contamination. The existing DP sensor couldn’t accurately measure such minute changes because its resolution was too coarse. Specifically, it had a minimum detectable differential of 100 Pa, which meant that critical pressure drops below that threshold went undetected. As a result, contaminants could migrate from non-sterile to sterile areas, compromising the entire batch. In fact, the physics of air movement dictates that even a 50 Pa difference can create a significant barrier to particle migration. Therefore, a sensor with higher sensitivity is essential.

How DR3425 Solved Our Cleanroom Contamination Issue

We replaced the inadequate sensor with the DR3425 Micro Differential Pressure Transmitter. This ultra-low range DP sensor is designed specifically for cleanroom pressurization measurement. It offers high sensitivity for tiny pressure differences, enabling precision air pressure control. The DR3425 can detect differentials as low as 10 Pa, far exceeding the 50 Pa threshold we needed. Additionally, it features a standard analog output for easy integration with our existing building management system. Consequently, we could finally monitor and control the cleanroom pressure with unprecedented accuracy.

$250,000 Annual Savings: How Precise Pressure Control Transformed Our Cleanroom

Installing the DR3425 provided immediate benefits. We were able to detect even 50 Pa differences, which previously went unnoticed. This small change dramatically reduced contamination incidents by 90%. Moreover, the improved air quality led to a 30% increase in batch yield. As a result, we saved over $250,000 annually in reduced rework and product loss. The DR3425 also paid for itself within the first month of operation.
