Pressure range and output signal
The MPX2202DP is a differential pressure sensor with a 29.01 PSI (200 kPa) operating range and a maximum overpressure rating of 58.02 PSI (400 kPa) — the overpressure ceiling is double the nominal span, giving margin for transient spikes in pneumatic lines without permanent offset shift. Its Wheatstone bridge output delivers 0 mV to 40 mV at a 10 V excitation — a millivolt-level signal that requires an external amplifier or ADC with sufficient gain before the microcontroller's input range. The 10 V to 16 V supply range means the sensor can run from a regulated 12 V rail common in industrial control panels.
Package and integration details
Housed in a 4-SIP through-hole module with dual barbed ports (male 0.19" / 4.93 mm tube) — the barbed style accepts flexible polyurethane or silicone tubing without a separate ferrule, and the dual-port configuration allows differential pressure measurement across a filter, orifice, or flow element. Termination is via PC pins that solder directly into plated through-holes on the PCB — no connector required, which saves board height and keeps the sensor close to the measurement point.
Temperature compensation and accuracy
This simplifies the BOM for applications that see wide thermal swings, such as HVAC duct pressure or pneumatic actuator feedback.
