High Accuracy pressure transmitter for Process Control
Pressure transmitter solutions for demanding industrial applications. The DR3422 series Low Differential Pressure Sensor delivers reliable performance.
The 20% Pressure Drop That Wasn’t Real
A plant manager called me at 2 AM: the HVAC system was showing erratic pressure readings and spiking energy consumption. Every time the VFD ramped up, the pressure reading dropped by 20%. The process was steady, but the signal was lying.
Low differential pressures in air systems are easily lost to sensor noise and drift. Traditional analog transmitters often have a noise floor that exceeds the signal we need to capture, leading to unreliable readings and wasted energy. In this case, the existing sensor’s 10% thermal drift overwhelmed the small pressure changes.
We switched to the DR3422 low differential pressure sensor. This digital gauge is designed for HVAC DP measurement and captures spikes up to 2500 bar with high accuracy at low differentials. Its digital architecture minimizes noise interference, ensuring consistent performance even under fluctuating conditions.
Key Specifications:
- Differential pressure transducer
- Low pressure drop measurement
- Compact size for tight spaces
- High accuracy at low differentials
- Ideal for air and non-corrosive gases
After installation, the 20% drop vanished, and energy consumption dropped by 15%. The sensor’s low noise floor allowed accurate measurement of the air pressure drop across filters, enabling timely filter changes.
