Array Electro-magnetic Thickness Instrument

DCH series Array Electro-magnetic Thickness Instrument is used to measure the thickness of downhole metal pipe, which can reflect the corrosion degree of casing. The sensor array of the instrument is composed of 16 (12) independent sensors. Every sensor can get a curve of casing thickness. Technical parameter Max OD： 43/70mm Length： 2400/2600mm Number of sensors： 12，16 Working temperature： 175℃ Max pressure： 100 Mpa Measurement range of ID： 3.5〞～ 7〞 ( 43mm ) 4〞～9 5/8〞( 70mm ) Wall thickness measuring accuracy: 15% of pipe wall thickness (undamaged pipe) Working voltage： 90V Working current： 30mA-70mA
