Model LR-Cal LPC 300
The electronic pressure calibrator LR-Cal LPC 300 is used for high precision calibration of pressure instruments, e.g. pressure gauges, pressure transmitter, digital manometer, pressure switches, overpressure protection valves, etc.
The LR-Cal LPC 300 is a very user-friendly, accurate and compact solution for pressure comparison calibrations. The built-in reference sensor LR-Cal LPC-S is changeable; several pressure ranges can be covered with one LR-Cal LPC 300 unit (up to 10).
All standard pressure ranges between 0...250 mbar (0...4 psi) and 0...1000 bar (0...14500 psi) are available as well as vacuum and absolute pressure ranges in accuracy 0.025% FS. Furthermore, ranges up to 8000 bar (116000 psi) are available with accuracy 0.1% FS.
The electronic pressure calibrator LR-Cal LPC 300 measures pressure, volts and milliamps and supplies 24 VDC as source for transmitter. Calibration procedures can be pre-defined and used for calibrations on site. The LR-Cal LPC 300 is featured with USB- and RS232-interfaces and is powered by a chargeable Lithium-Ion battery pack (no "memory effect").

The reference pressure sensors LR-Cal LPC-S are equipped with a welded stainless steel membrane, they are suitable for aggressive media, which do not destroy stainless steel 1.4571.
The electronic pressure calibrator (documenting process calibrator) LR-Cal LPC 300 can be operated in three different modes:
Measuring Mode:
First, the operator defines the unit under test (analogue or digital, pressure range, accuracy class, pressure unit, gauge or absolute pressure, gaseous or fluid calibration medium, power supply 24 VDC on or off).
Then, the comparison calibration can be made: The display shows the pressure range of the LR-Cal LPC-S reference sensor, the true pressure measured by the LR-Cal LPC 300, the pressure range of the unit under test, the output signal of unit under test (measured if it is a transmitter, to be entered manually if it is an analogue pressure gauge), deviation in selected pressure unit of unit under test, deviation in percentage of full scale value of unit under test.
With one view the operator sees wether the unit under test is within it's specification (accuracy class) or not - at every test point.
15 different pressure units are available for selection, plus an user-definable pressure unit. The resolution adjustment (decimal point setting) can be made very comfortable.
Calibration Mode:
In this mode, calibration procedures can be pre-defined, incl. management of units under test. One procedure has following data: Same like "Measuring Mode", plut Calibration Number (program no.), Serial number of unit unter test, location number of unit under test, test pressure points (up to 32 for each unit under test), dwell time (seconds) between test pressure points.
Up to 16 units under test with each 32 test points can be managed by the LR-Cal LPC 300 at a time.
Later on, it can be worked on the pre-defined calibration procedures, e.g. on site. The values are saved in the internal memory of the LR-Cal LPC 300 and can be transmitted to a PC via the USB- or the RS232-interface.
Also, in this "Calibration Mode", the operator can see on one view wether the unit under test is within it's specification or not.
With the optional PC software LPC-Cal the calibration data can be downloaded to a Windows-PC and printed out (via MS-Excel).
Pressure Switch Test Mode:
After specification of the unit under test (pressure range, power supply 24 VDC On/Off), the electronic pressure calibrator LR-Cal LPC 300 shows the actual status of the pressure switch.
Settable basic parameters:
Several basic parameters can be entered into the LR-Cal LPC 300, e.g. ambient temperature, fluid level difference between reference and unit under test, Language (English/French/Italian/Spanish/German), Setting of the realtime clock, Setting of the display, Setting of the powersafe function, Indicating battery level, Tara value (offset), Indicating Min/Max values, Setting/indicating alarm values, Digital software filter, USB- and RS232 settings.
