High Pressure Controllers

Dead Weight Type

The Controllers are designed to maintain confining pressure at the set value with the help of dead weights irrespective of any deformation that takes place during testing of the specimen. A series of relays are provided for automatic actuation of the main pumping unit depending upon the volume change in the specimen. A small fractional horse-power geared motor eliminates any static friction, by rotating the measuring ram.

All the electrical controls are easily accessible and are mounted on the front panel.

The unit operates on 440 volts, 3 phase, 50 hz supply.

HR72.65 – 0.1 – 7 Mpa in steps of 0.1 Mpa
HR72.70 – 0.2 – 15 Mpa in steps of 0.2 Mpa
HR72.75 – 0.5 – 35 Mpa in steps of 0.5 Mpa
HR72.80 – 0.5 – 50 Mpa in steps of 0.5 Mpa
HR72.85 – 0.5 – 70 Mpa in steps of 0.5 Mpa

Note : Higher Pressure Controller on request.

Digital High Pressure Controller

The Controllers are designed to maintain confining pressure at the set value with the help of servo closed loop feedback principle. Sensing back is from a sensitive pressure transducer. Pressure is maintained within the range of +/-2 % irrespective of any deformation that takes place during testing of the specimen. A series of relays are provided for automatic actuation of the main pumping unit depending upon the volume change in the specimen. This unit can be operated by Touch panel based front display to set the pressure/ computer.
