ACE – Automatic Computerized Oedometer

The Automatic Computerized Oedometer (ACE) requires a maximum air pressure supply of 10 bar for optimal operation. This level of air pressure is necessary to effectively power the pneumatic components of the device, such as the servo-valves and cylinders, which are critical for applying accurate loads during soil testing.

In cases where a laboratory does not have an existing air pressure line suitable for this requirement, an alternative solution is provided. The recommended alternative is the Air compress model NG-D2015, which has a capacity of 50 liters. This air compressor model is designed to complement the ACE, ensuring that it receives the necessary air pressure for its functions.

The availability of this alternative air compressor model ensures that the ACE can be used in a wide range of laboratory settings, even those that do not have pre-existing pneumatic infrastructure. This flexibility enhances the usability and accessibility of the ACE, making it a practical choice for various soil testing applications in different environments. The provision of a dedicated air compressor model also guarantees that the ACE will operate efficiently and reliably, providing consistent results in soil mechanics testing.
