LR-Cal LPP 140-P
Pressure comparison test pump
Pneumatic, -0.95...+140 bar
Description
LR-Cal LPP 140-P description
This pneumatic pressure comparison test pump is used to generate test pressure for checking, adjusting and calibrating all types of mechanical and electronic pressure measuring devices by means of comparative measurements. The LR-Cal LPP 140-P pressure comparison test pump requires a solid base (e.g. a workbench).
If the pressure measuring device to be tested and a suffciently accurate reference pressure measuring device are connected to the pressure comparison test pump, the same pressure acts on both measuring devices when the pump is actuated. By comparing the two measured values at any pressure value, the accuracy or adjustment of the unit under test can be checked.
The LR-Cal LPP 140-P pressure comparison test pump is equipped with a fne adjustment valve for precise approach of the measuring points. The test pump uses ambient air as the test medium. It is characterized by its simple and effective handling and works independently, so no external pressure source is required.
Note:
The performance of the pressure comparison test pump LR-Cal LPP 140-P depends on the total volume of the calibration circuit. The lower the volume, the higher the performance. The larger the volume, the more sensitively the test pressure can be adjusted.
