EX-F71-PN

Specialized Sensors

EX-F71-PN is a specialized sensor created by Yokogawa Electric Corporation. It is a piezoelectric strain gauge transducer that measures pressure and eddy current displacement. The EX-F71-PN is used in a variety of industrial applications such as in the aerospace industry, manufacturing industry, process control industry, and automotive industry making its application field quite expansive. Here, we will discuss the working principle of the EX-F71-PN.

Working Principle

The EX-F71-PN is a piezoelectric transducer that works on the principle of piezoelectric effect. This effect is produced when a certain type of quartz crystal is stressed, the crystal is able to produce an electrical pulse proportional to the applied stress and increasing in magnitude as the pressure is increased. The output of an EX-F71-PN transducer is an electrical pulse proportional to the amount of strain on the crystal. By measuring the output of the transducer, the pressure or eddy current displacement on the crystal can be accurately measured. The EX-F71-PN sensor also has a high level of accuracy and a very low noise level, making it ideal for applications that require precise and accurate measurements.

At its core, the EX-F71-PN transducer is a quartz crystal sensor with a pressure-sensing diaphragm. The diaphragm is connected to the quartz crystal, and the pressure applied to the diaphragm causes the quartz crystal to produce an electrical pulse. The pulse is then amplified and converted into an output voltage that is proportional to the amount of pressure applied to the diaphragm. The output of the EX-F71-PN transducer can then be used for a variety of applications such as pressure and level monitoring, pressure mapping, and strain measurement.

Signal Output

The EX-F71-PN has a signal output of 4-20 mA and can be connected to a variety of systems like a PLC or a SCADA system. The signal output of the EX-F71-PN transducer is linear and temperature compensated so that the accuracy is not affected by temperature changes. The accuracy is also enhanced through the signal compensation feature of the EX-F71-PN transducer. This feature allows the user to adjust the signal output voltage of the transducer so that it can better match the system it is connected to. The EX-F71-PN has a low power consumption, making it ideal for applications where power is limited.

Conclusion

In conclusion, the Yokogawa EX-F71-PN is a specialized transducer that works on the principle of the piezoelectric effect. This effect produces an electrical pulse proportional to the amount of pressure applied to the diaphragm of the transducer. The EX-F71-PN has a signal output of 4-20 mA and is capable of accurate and precise measurements. This makes the EX-F71-PN ideal for use in a variety of industrial applications.
