🛡️ The Importance of Installing Wind Shields on Differential Pressure Transmitters

Pressure Transmitter /

Differential pressure transmitters with small measuring ranges are highly sensitive to environmental interference. When installed in wind-exposed areas, strong airflow can create pressure on the negative-pressure port, resulting in inaccurate readings and compromising measurement accuracy. To mitigate the influence of external airflow and environmental fluctuations, it is recommended to install a downward-facing impulse line and […]
