FAQs
How does a strain-gage pressure transducer work?
A strain-gage pressure transducer measures pressure by using strain gauges bonded to a sensing element. As pressure is applied, the sensing element flexes slightly, causing the strain gauges to change their electrical resistance. This change is converted into an electrical output that accurately represents the applied pressure. Strain-gage pressure transducers are widely used in military, aerospace, industrial, and test equipment applications because they provide reliable and accurate pressure measurement.
What is millivolt output?
Millivolt (mV) output is a low-level electrical signal produced by a pressure transducer in response to applied pressure. The output is proportional to the pressure being measured and is typically used with signal conditioners, amplifiers, or data acquisition systems. Millivolt output pressure transducers are commonly used in military and laboratory applications where high measurement accuracy is required.
Why is a hermetically sealed connector important?
A hermetically sealed connector protects the internal electronics of a pressure transducer from moisture, dust, corrosion, and other environmental contaminants. This sealed construction helps maintain long-term reliability and accurate performance in harsh operating conditions, making it ideal for military, aerospace, and industrial applications.
What is the purpose of NSN 6670-01-067-8954?
NSN 6670-01-067-8954 is the National Stock Number assigned to the DF6139 Pressure Transducer. The NSN allows military organizations, government agencies, and defense contractors to identify, order, and replace the correct component through standardized military supply and logistics systems. Using an NSN helps simplify procurement and ensures the correct part is supplied.
Why are military pressure transducers different?
Military pressure transducers are designed to meet strict performance, durability, and reliability requirements for defense and aerospace applications. Compared to standard commercial pressure transducers, they are built to withstand harsh environments, vibration, shock, temperature extremes, and demanding operating conditions. Military pressure transducers also comply with military specifications, undergo rigorous quality testing, and are often assigned a National Stock Number (NSN) for standardized procurement.
