AT25 Electronic Logging Pressure Gauge Application Areas Model AT25 logging Electronic Pressure Gauge is mainly used in production well logging in the oilfields. It is capable of measuring down-hole flowing pressure, static pressure and pressure build-up, etc. Features This product adopts the latest strain pressure sensor imported from U.S.A. and adopts imported high-temperature resistance electronic components in circuitry. It is powered by a single power source and outputs pulse signals. It is characterized by stable signal output, high sensitivity, fine linearity, less temperature drift and high accuracy. It can be connected to any surface computerized logging system. Technical Specifications 1. Working environment: (1). Pressure: ≤ 70MPa (2). temperature: ≤170℃ 2.
