With integrated electric pump -0.85...+20 bar (-12...+300 psi)
The compact designed pressure calibration case LR-Cal LPK 300-PP can be used portable as well as stationary. The rugged case makes it suitable for harsh operating conditions also.
The LR-Cal LPK 300-PP, through its integrated electric pump, enables the provision of -0.85 to +20 bar (-12...+300 psi). Due to the integrated electric pump, the operator can supply the test item to be calibrated with pressure or vacuum on-site and does not need any separate pressure supply for pressure ranges up to 20 bar. The fine pressure adjustment is to be carried out via the manual sensitive volume fine adjustment valve.
The LR-Cal LPK 300-PP is a very user-friendly, accurate and compact solution for pressure comparison calibrations. The separately to be ordered reference sensor LR-Cal LPC-S is changeable. Several pressure ranges can be covered with one instrument.
All standard pressure ranges between 0...250 mbar (0...4 psi) and 0...1000 (0...14,500 psi) are available. For operations with pressure ranges over 20 bar, a pressure test pump is required in addition.
The pressure calibration case LR-Cal LPK 300-PP measures pressure, volts and milliamps and supplies 24 VDC as source for transmitters as unit under test. Calibration procedures can be pre-defined and used for calibrations on site. The LR-Cal LPK 300-PP is featured with an USB interface and is powered by a chargeable Lithium-Ion battery pack.
