ER-QPS-19 Oil and Gas Quartz Pressure Sensor
Introduction
The current diameter of the sensors is mainly Φ19, the length is different due to the pressure sensor's different models. There are two main structures, one is the sensor's line outer barrel could not withstand the pressure, it needs to be installed in the inside of the downhole instrument, the advantage is facilitating outside bus line of the sensor over the line.
Ericco’s high temperature and high pressure quartz pressure sensors for oil and gas have the characteristics of high reliability and high precision. For decades, the international petroleum industry has always used this quartz crystal pressure gauge as the industry pressure measurement standard. The pressure sensitive element is a quartz resonator, and the output frequency changes with increasing pressure.
The sensitive element maintains the inherent high repeatability and high stability of single crystal quartz. At the same time, there is a temperature probe with a quartz resonator that can directly perform digital temperature compensation on the pressure value. The sensors provide independent pressure frequency signals and temperature frequency signals, and can calculate the temperature-compensated pressure value within the pressure and temperature measurement range. There is no DC signal processing in the sensor circuit, and no DC standard power supply is needed, and the frequency signal is directly output. It can be easily used in memory recording tools and cable recording tools, and the signal output can be adapted to the requirements of any measurement circuit.
