Pressure Sensors and Transducers are essential components in a variety of industrial applications. The NPA-700B-030G is a highly versatile, reliable, and performance-oriented pressure transducer, suitable for a range of applications in industries such as aviation, aerospace, pharmaceuticals, automotive, and energy. Let’s take a closer look at the technical specifications and capabilities of this transducer, as well as its most suitable applications and working principles.

Technical Specifications

The NPA-700B-030G is available in a variety of configurations. Its model numbers start with an “NPA” prefix and are followed by a “700B” suffix. The last three digits indicate the pressure range in PSI. For example, the 030G model measures pressure from 0 to 30 PSI. It is made of lightweight and durable aluminum alloy and can withstand extreme operating conditions, such as temperatures ranging from -55°C to 105°C and a maximum operating pressure of 300 PSI. The NPA-700B-030G also features a built-in temperature sensor, making it suitable for monitoring processes subject to rapid changes in temperature. In addition, this transducer has a wide frequency response from 0 to 10 kHz and a low zero-point stability of 0.1%.

Application Field

Due to its versatility, the NPA-700B-030G is suitable for a wide range of applications. As mentioned before, it is widely used in the aerospace, automotive, and energy industries. It is often part of the monitoring system of pilot’s oxygen supply on aircrafts, monitoring pressure levels of fluids in automotive engines, measuring process pressure levels in energy plants, as well as in pharmaceutical production processes. Recently, the wide frequency response makes this pressure transducer suitable for use in high frequency ultrasonic systems, such as medical imaging systems and robotic cutting tools.

Working Principles

Pressure transducers, such as the NPA-700B-030G, are typically piezoelectric devices. They contain a sensing element, which is a diaphragm or filament that responds to changes in pressure. This diaphragm, created from a piezoelectric ceramic, is charged with an electric current when pressure is applied to it. This electric current is then converted to a voltage, which is proportional to the applied pressure. This voltage is transmitted to a signal conditioning module, where it is converted to a standard output signal, such as 4-20 mA or 0-10 V, which can be read by the monitoring system.

Conclusion

The NPA-700B-030G is a highly effective and reliable pressure transducer from Aerotech Specialty Instruments. With its wide frequency response and low zero-point stability, it is suitable for use in a variety of industries, including aerospace, automotive, and energy. Its technical specifications make it an excellent choice for monitoring processes subject to rapid changes in temperature. The working principle of this transducer makes it easy to integrate into existing monitoring systems and provides highly sensitive and accurate measurement results.
