Введение продукции

The filter differential pressure sensor receives one pressure line from each side of a HEPA filter, prefilter or air-handling coil. Its low-pressure element converts the difference into a continuous signal that rises as resistance builds at a given airflow. Monitoring systems can trend the value and generate a maintenance alarm before the filter causes excessive fan demand or airflow loss. Clearly separated high and low ports, colored tubing and serviceable zero adjustment reduce common installation errors.

Основные характеристики

Dual pressure taps isolate filter resistance from the surrounding duct static level.

Continuous output shows the rate of loading instead of only a single switch point.

Adjustable alarm and hysteresis support planned maintenance before severe restriction.

Colored pressure lines and labeled ports reduce upstream-downstream connection errors.

Обеспокоенность клиентов продуктами

Filter pressure drop depends on airflow as well as loading, so reliable interpretation requires correct pressure connections and trend context.

Maintenance changes filters on a fixed schedule without knowing actual loading.Continuous differential trends reveal how resistance develops under real operation.

Reversed pressure tubes produce a negative or misleading reading.Red-blue tubing and marked high-low ports preserve upstream-downstream orientation.

A brief fan-speed change triggers a false dirty-filter alarm.Delay and hysteresis prevent a short airflow transition from being treated as sustained loading.

A damaged or missing filter creates an unexpectedly low pressure drop.Low-differential alarms can identify probable bypass or absent media as well as high loading.
