Digital Data Loggers

Model: DDL-3
The measurement system is equipped with 3 sensors, a recorder, and an optional computer, which can simultaneously record up to 3 sets of pressure values. It is also possible to record only one or two sets of data according to measurement needs.

Meet the API 16TR testing requirements, and record the real-time opening oil pressure, closing (Shear) oil pressure, and well pressure for the shear test of the blowout preventer.

Using a high-frequency recorder, record the maximum pressure value at the moment of shearing.
