The NPA-500B-02WD is a surface-mount pressure sensor designed for differential pressure applications with amplified analog output and 5V excitation. This compensated sensor features dual barbed ports for easy integration into fluid systems and operates over a pressure range of 10" H2O to 30 PSI with a total error band of ±1.5% FSO. The sensor provides an offset voltage of 0.44 to 0.56 Volts and a span of 4 Volts, with a proof pressure rating of 60 psi for the 5 to 30 psi range. Operating across a temperature range of -40°C to 125°C with an on-chip temperature sensor capability, this sensor is ideal for HVAC systems, medical devices, and industrial process control applications requiring reliable differential pressure monitoring.
