The LR-Cal LSP 4000 serves as pressure generator for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. The device can be used in the laboratory or workshop, or on site at the measuring point.

By connecting the test item and a sufficiently accurate reference pressure measuring instrument to the test pump, 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 under test can be carried out.

The integrated dual-area spindle pump with switching valve enables rapid filling of the test system and smooth pressure generation.

At the same time, the precisely adjustable spindle pump also serves for fine pressure adjustment. A control schematic for pressure generation on the instrument base facilitates quick and easy operation.

The two test connections are equipped with 1/2" BSP female loose union connections with double ended metal cone. Two threaded adapters mounted on M16x1.5 male thread are included in the scope of standard delivery. Further thread adapters are available for the calibration of instruments with different connection threads.
