The P4055-150G-E4A is a pressure transducer designed to measure gauge pressure in a 0–150 PSI range with a back-side PRT configuration compatible with liquid and gaseous media. It features a ratiometric 0.5–4.5 VDC output signal powered by 5 VDC ± 5% supply, with power consumption of =25 mW and a response time of =10 ms to 63% of full scale. The transducer incorporates a Packard Metri-Pack 150 electrical connector, brass housing, 1/4-18 NPT pressure port, and fluorosilicone internal seal material, with an operating temperature range of -40°C to +125°C and IP67 ingress protection. It delivers high vibration tolerance (10 G's peak-to-peak sinusoidal, 20–2000 Hz), shock resistance (75 G's ½ sine wave), and a total error band of ±2% of span across the operating temperature range. This compact sensor is ideal for pumps, compressors, process controls, filter restriction monitoring, oil and fuel pressure measurement, water management, and test equipment applications.
