ultrasonic transducer design
The wide world of the oil industry uses many types of pressure sensor control and measurement in processes, controls and hole drilling tools. With the need to find oil in more inaccessible places the equipment used in exploration, drilling and production becomes ever more complex and use of pressure transducer products is increasing.
Some uses pressure transducer sensors are:
Heads
Head Assemblies the well and the Christmas tree using a series of sensors monitor the pressure of the pressure transducer head. Due to the hazardous area the pressure transducer should be intrinsically safe or explosion-proof design. A pressure sensor used in this application must also be robust and weatherproof. The series Omni 23IS types 23EXD and pressure sensor to meet both requirements.
Downhole Tools
Different types of pressure sensors are used in downhole tools to control the hydraulic pressure and the pressure pipeline. Often a high pressure sensor is needed, with the temperature range of operation is high due to the extreme environment. The Omni series 10 and 8 pressure transducer series models offer ranges up to 1000 bar at temperatures up to 150 degrees C.
Submarine Hydraulic Manifolds
Submarine Hydraulic Packages are used to control various applications of oil production offshore. Packages submarine water may use up to 10 units of pressure transducer. The pressure transducer design should be smaller, and be able to work with high If external pressures. In this case the pressure sensor can be eliminated external enclosure with the PCB exposed naked to the environment to reduce the profile, with oil from , used to stop the penetration of sea water
Smart Pigs
Underwater pipelines are regularly tested with a smart pig. The pig can be equipped with various types of pressure sensor to monitor pressure pipe and hydraulic pressure. Also a differential pressure sensor can be used to measure the pressure difference between front and rear of the pig. As these devices are generally powered by a battery, it is important to choose a sensor pressure with low power consumption. The Omni series 10 pressure transducer is based on only about 1 mA and is ideal for these applications.
Basic Analysis
In the basic analysis of a sample of oil can be forced under high pressure in a section of Rock Center. A pressure sensor in this application must provide a measurement accuracy of up to 10,000 psi high and is being constructed or hastelloy monel to avoid corrosion of the membrane. The Omni series 23 and 25 of the pressure sensor fulfills this requirement.
The drilling mud Systems
It is often the requirement to use a pressure sensor in the mud flow lines. In these applications, requires a membrane pressure transducer with color. Moreover, a pressure sensor port standard pressure is only 3 mm in diameter, and is prone to clogging with sludge particles. The Omni series 25 pressure transducer has a G1 / 2 "G3 / 4" color and the diaphragm can send Exd are provided or format for use in hazardous areas.
