Hydrostatic Pressure Test After undergoing hydrostatic pressure tests at 3MPa/1h, 0MPa/0.25h, 3MPa/1h, and 0MPa/0.25h, the insulation resistance between the transducer core wires and between the core wires and the outer casing was greater than 100MΩ.
Measurement Results: The transducer meets the technical specifications.
