Automated confining pressure and temperature controller Instruments

The Automated confining pressure and temperature controller Instruments generates and maintains the desired confining pressure and temperature during porous media studies. It is particularly useful for NMR, CT scan and linear X-ray experimental setups with composite core holders, when air baths cannot be utilized. The device consists of a high pressure-high temperature syringe pump, a recirculation pump, a pneumatic dual valve, a fluid reservoir and two pressure transducers for pore and confining pressure monitoring.

The syringe pump generates and maintains constant pressure and temperature up to 10,000 psi and 150°C, respectively. Meanwhile, the recirculation pump assures continuous flow in the confining circuit. Consequently, the core sample mounted in the core holder is maintained under the same conditions of temperature and pressure. The system can also be used to maintain a constant differential pressure between the pore pressure and confining pressure. By means of an Ethernet connection and dedicated software, the ACP-700-150 series can easily be programmed to perform elaborate pressure and temperature maintenance schedules.
