Pneumatic calibration pump LPP series

manualfor pressure and vacuum

The pressure test pump LR-Cal LPP 60-T is used to generate pressures and vacuum for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These pressure tests may be carried out in laboratories, workshop or on site at the measuring point. If the instrument under test and a sufficiently accurate reference measuring instrument (e.g. electronic pressure calibrator LR-Cal LPC 300 or LR-Cal LPC 200, accuracy ±0.025% FS) are connected to the LR-Cal LPP 60-T, the same pressure pressure resp. vacuum is applied to the two instruments when the pump is operated. Despite its compact dimensions, the pneumatic pressure comparator LR-Cal LPP 60-T is easy to operate and allows for exact generation of the required test pressures. A change-over switch enables the generation of vacuum as well. The LR-Cal LPP 60-T is fitted with a fine adjustment valve for the precise adjustment of pressures. The reference instrument is screwed directly on to the top of the pump and the unit under test is connected by means of a connection tube incorporating an adapter 1/4" BSP rotating female (optional 1/4" NPT female) port. Included in standard supply: Pressure comparator / pressure test pump LR-Cal LPP 60-T with pressure port for reference instrument 1/2" BSP female rotating with O-ring sealing Aluminium base plate Pressure test hose 0.5 m with pressure port 1/4" BSP female rotating for test item Operating manual Generation of pressure and vacuum -0.95...+60 bar Pneumatic (operated with ambient air) Making pressure up to +60 bar (870 psi) Making vacuum down to -0,95 bar (-28 inHg) Very easy operation, fine volume adjustment
