Pressure source for calibration purposes. Pressure comparison pumps LSP are used for generating pressure for the testing, adjusting and calibrating of mechanical and electronic pressure mesuring instruments by means of comparison measurements. These pressure tests can be carried out in laboratories, workshops or on site at the set measuring point.
When the device under test and a reference measuring instrument with an adequate accuracy are connected to the LSP 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 pumps LSP are provided with a fine adjustable spindle pump. In addition, the series LSP feature a threaded spindle which only runs within 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 series LSP needs only little force to generate also high pressures.
