The 8810 for setting pressures with ranges from 0 to 350 bar
Liquid and gas separator 2255
The gas pressure module model 2255 is connected to a high pressure gas cylinder and on the other side to the oil gas separator model 8335 which can be connected to, for example, a hydraulic deadweight tester. The instrument under test is connected to the 2255 pressure module. The 8335 buffer contains a sight glass. Here the oil level can be controlled by means of the spindle pump on the deadweight tester. The gas pressure for each test or calibration is controlled by ne control valves on the 2255 control unit. This keeps the instrument under test from coming into contact with the oil from the deadweight tester. In this way, you can easily and safely use a hydraulic deadweight tester.
