Description
The Dwyer Instruments A-420A Outside Static Pressure Sensor which delivers precise measurements of outdoor pressure for HVAC applications. The NEMA4X-rated enclosure protects this sensor from harsh weather conditions while shielding it against water dust and corrosion. The product operates dependably across all conditions because of its sturdy design. The sensor useds a piezoresistive pressure transducer that generates a linear output signal based on applied pressure measurements. The precise pressure level monitoring capability of this feature enables essential control needed to achieve optimal HVAC system performance.
