Hydraulic (with oil or water) operated pressure comparison test pumps models
serve as pressure generator for the testing, adjustment and calibration of mechanical end electronic pressure measuring instruments through comparative measurements. The devices can be used in the laboratory or workshops.
By connecting the test item (unit under test / UUT) and a sufficiently accurate reference pressure measuring instrument to the LR-Cal pressure comparator, the same pressure will act on both measuring instruments. By comparison of the two measured values at any given pressure value, a check of the accuracy and/or adjustment of the pressure measuring instrument unter test can be carried out.
This LR-Cal pressure comparators, manufactured in our own facilities in Kirchentellinsfurt (closed to Stuttgart in the south of Germany) are 100% tested for performance, functionality and tightness, before they are shipped to our customers.
