Micro DP Sensors for Precision Air Pressure Control

Pressure transmitter solutions for demanding industrial applications. The DR3425 series Ultra Low DP Sensor delivers reliable performance.

Cleanroom Pressure Control: Solving 20% Deviation with an Ultra Low DP Sensor

At a BioTech Manufacturing facility in Silicon Valley, we faced a critical issue: our cleanroom pressurization system showed deviations up to 20% from the 10 Pa setpoint, despite smooth VFD operation. The culprit? The DR3425 differential pressure sensor couldn’t handle the ultra-low range required.

Why Ultra-Low DP Sensors Matter in Cleanrooms

Cleanroom environments demand precise pressure differentials—a single microbar (100 Pa) fluctuation can compromise airlock effectiveness and contamination control. Standard industrial pressure gauges lack the sensitivity for such tiny differences. The physics is straightforward: accurate measurement of 50Pa differentials requires a sensor with high resolution and stability, especially when trace particles or ambient changes can skew readings.

The Fix: A Cleanroom Pressure Monitor That Works

After replacing the DR3425 with a new unit, deviations dropped to ±10 Pa within two weeks. The key was an ultra low DP sensor designed for cleanroom pressure monitor applications, capable of measuring differentials as low as 50 Pa with high sensitivity. This precision air pressure control restored stable operation.
