Calibration Test Pump LPP 30, pneumatic operated
to generate pressure up to +35 bar / +500 PSI
switchable to generate vacuum up to -0.95 bar / -28 inHg
The Calibration Test Pump LPP 30 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 LPC 300 or LPC 200, ±0.025% FS) are
connected to the LPP 30, the same pressure / vacuum is applied to the two
instruments when the pump is operated.
Despite its compact dimensions, the calibration test pump LPP 30 is easy to
operate and allows for exact generation of the required test pressures. A changeover
switch enables the generation of vacuum as well. The LPP 30 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 (or 1/4" NPT female) port.
