Abstract:  In order to overcome the disadvantages of traditional oil and water well parameter acquisition methods,
such as complex operation and low precision and so on, a new type of measuring instrument based on wireless
radio frequency technology was designed. The design principle and method of the gauge were explained. The
wireless radio frequency sensor which was packaged including the sensor module (pressure, current) took charge
of data collection of oil and water wells and the RFID read-write module, by which the oil and water wells data
was written into the RFID card. For the testing instrument, the system structure is simple, stable and reliable.
The accuracy of data acquisition meets the requirement and has changed the traditional mode of data acquisition.
By utilizing this Instrument, the workload of the staff is greatly reduced and the work efficiency is improved.
Therefore, the designed wireless radio frequency sensor detection instrument is effective.

Key words:  radio frequency identification (RFID), testing instrum, pressure sensor
