Pressure sensors, transducers, and other devices are in wide use today for a variety of applications. The purpose of such devices is to measure pressure and convert it into an electrical signal. One such device is the NPC-1210-001D-3-L, a pressure transducer made by NXP Semiconductors. This particular model is a capacitive type with two parallel electrodes on its sensing diaphragm. This article will discuss the application field and working principle of the NPC-1210-001D-3-L.

Application Fields:

The NPC-1210-001D-3-L is designed for use in industrial manufacturing and process control applications. These applications are typically related to HVAC (heating, ventilation, and air conditioning) systems, water purification systems, and various other process control applications. This device is benchmarked to NXP’s own reference designs for ease of integration into existing systems, so it performs well in a wide variety of conditions. In addition, the device features a high degree of stability which makes it suitable for many long-term applications.

Working Principle

The NPC-1210-001D-3-L works on the principle of capacitance. This device uses two parallel plates on its sensing diaphragm, with one plate attached to the pressure to be measured and the other plate connected to an electrical signal. As the pressure changes on the sensing diaphragm, the capacitance between the two plates changes. This change in capacitance is converted by the device into a proportional change in voltage or current, which can then be measured and interpreted by the user.

The device has a range of 0 to 10 bar (145 psi), and operates in a temperature range of -35°C to +135°C. It is powered through an integrated amplifier, which is powered by two 0–5 V power sources. Additionally, the device has two digital IO pins which allow for either external data acquisition or the addition of other peripheral devices. All of this makes the NPC-1210-001D-3-L a highly versatile and durable pressure transducer.

Conclusion

In conclusion, the NPC-1210-001D-3-L is an excellent example of a capacitive-type pressure transducer, and suitable for a wide range of applications. It is relatively easy to integrate into existing processes, can be powered by a variety of power sources, and is capable of measuring pressures up to 10 bar. Furthermore, its high degree of stability makes it ideal for long-term applications. All of these factors make the NPC-1210-001D-3-L an excellent choice for pressure transducer applications.
