The P4055-100G-E4A is a pressure transducer designed to measure gauge pressure in a 0–100 PSI range with a back-side PRT configuration compatible with liquid and gaseous media. It features a 0.5–4.5 VDC ratiometric output signal, operates on a 5 VDC ± 5% supply, and consumes =25 mW of power. The transducer includes a Packard Metri-Pack 150 electrical connector, brass housing, and is available with 1/4-18 NPT or 1/8-27 NPT pressure ports. It delivers a response time of =10 ms to 63% of full-scale pressure, withstands 10 g peak-to-peak sinusoidal vibration (20–2000 Hz), and is rated for 1 million full-pressure cycles over its operating life. This compact, temperature-compensated sensor is ideal for pumps, compressors, process controls, filter restriction monitoring, and fuel/oil pressure measurement applications.
