Dwyer Instruments 1910-0 Differential Pressure Switch 0.15"-0.55" WC

The Dwyer Instruments 1910-0 Differential Pressure Switch is an essential part for measuring pressure variations in HVAC systems particularly in the range of 0.15”WC to 0.55”WC. This switch compares pressure at two different points and will be useful in controlling the airflow as well as performing practically in applications like air conditioning, ventilation among others. Through controlling air flow rate and assessing the condition of filters it optimizes the system, decreases energy consumption. This is especially useful for fan control and variable air volume systems, where it is essential to maintain the right airflow.
