Product Overview
The Amphenol Advanced Sensors NPH Series Low Pressure Sensors are solid-state, high-reliability devices designed for PC board mounting in a standard TO-8 package. Offering a low cost and small size, these sensors are available in gauge, absolute, and differential pressure versions. They are media compatible with non-corrosive gases and dry air, featuring a typical thermal accuracy of 0.5% FSO and overpressure capability up to five times the maximum rated pressure. The NPH Series utilizes SenStable processing technology for excellent output stability and a laser-trimmed, thick-film resistor network for temperature compensation. Key applications include process control, pneumatic and HVAC systems, and biomedical and aerospace instrumentation.
