Product Overview
The Amphenol Advanced Sensors NPH Series offers solid-state, low-pressure sensors designed for high reliability and cost-effectiveness. Housed in a standard TO-8 package for PC board mounting, these sensors are available in gauge, absolute, and differential pressure versions. They are media compatible with non-corrosive gases and dry air, featuring thermal accuracy of 0.5% FSO typical and nonlinearity of 0.05% FSO typical. The NPH Series is suitable for a wide range of applications including process control, pneumatic and HVAC systems, biomedical devices, and aerospace instrumentation.
