The pressure comparison pump LR-Cal LSP-7000 is used to generate pressure for calibration purposes, for checking and calibration of any kind of pressure instruments in the laboratory as well as in the field, by means of comparison.
When the device under test and a reference measuring instrument with an adequate accuracy are connected to the test pump, the same pressure will act on both measuring instruments after actuating the pump. A calibration or an adjustment can be carried out by comparing the two measured values at any pressure value.
In order to enable an accurate generation of the measuring points, the pressure comparison pump LR-Cal LSP-7000 is provided with a fine adjustable spindle pump. In addition, the LR-Cal LSP-7000 feature a spindle which only runs withing the pump body. Thus there is no adverse bending moment acting on an outstanding spindle, and particularly for field use this has the advantage that the dimension of these pressure comparison pumps will not change when the spindle is turned during operation. The LR-Cal LSP-7000 needs only little force to generate also high pressures.
