Product Description
Amphenol Advanced Sensors NPI-19J-050A2 is a high-performance Pressure Sensor engineered for absolute pressure readings from 0 to 50 psi with digital output. Designed to deliver precision, sensitivity, and exceptional linearity, the NPI-19 Series utilizes silicon sensor technology and incorporates SenStable® processing for excellent output stability.
The sensor is well-suited for use in harsh and demanding industrial, HVAC, laboratory, and manufacturing environments, thanks to its rugged stainless steel housing and extended temperature range from -40°C up to 125°C. It offers a digital I2C output protocol, allowing seamless integration into advanced control and monitoring systems. The 14-bit output provides high resolution and accurate data capture, making it ideal for applications demanding precision.
With an accuracy of ±0.25% FSO (BFSL) and a total error band of ±1% FSO, the device assures reliable and repeatable measurements. Supported media includes both liquid and gas, enabling versatile use across various fluids. The sensor's low current consumption (3 mA typical) and flexible supply voltage (2.5V - 5.5V) make it suitable for cost-effective and energy-efficient installations.
Measurement range covers 0 to 50 psi absolute. Digital I2C interface with 14-bit resolution. ±0.25% full-scale output accuracy ensures reliable performance. Stainless steel construction resists environmental and chemical degradation.
Compatible with both liquid and gas media. Wide operating temperature range (-40°C to 125°C). Overpressure and burst pressure ratings provide safety margins. SenStable® processing improves long-term output stability. Low power operation suitable for embedded and remote systems.
This sensor is ideal for industrial process monitoring, HVAC controls, laboratory instrumentation, and commercial applications requiring robust, compact, and accurate digital pressure sensing. Whether monitoring pipelines, tanks, environmental chambers, or automated manufacturing equipment, the NPI-19J-050A2 provides reliable and precise measurements.
