For high accuracy of electronic gauge, it can reflect minor changeofpressure at down hole clearly and obtain information furthest.
电子压力计因其精度高，可以更清楚地反映井下的微小压力变化，最大限度地获取地层信息量。

ANEROID, a sealed flexible device containing air at low pressure, which expands or contracts during changeofpressure outside the device.
膜盒，内含低压空气的密封弹性装置。当它周围的压力变化时，会膨胀或收缩。
