Description
The Dwyer Instruments 1823-5 Low Differential Pressure Switch is a precision part used to measure low-pressure differentials in HVAC systems, targeting a 1.5” to 5” water column pressure range. This switch works through the differential pressure measurement of two points, which allows the system to control the airflow and keep the system in its better condition. Some of the most common areas of its use include air handling units, filter monitoring, and HVAC systems. The advantages of this pressure switch include the fact that it is capable of improving energy efficiency by varying the fan speed depending on the current pressure in the system.
