Electronic Pressure Calibrator LPC 300 (documenting)

LPC 300 multi functional Pressure Calibrator Accuracy ±0.025% f.s. Data Sheet Operating Manual LPC-Cal install manual

The electronic pressure calibrator 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 LPC 300 is a very user-friendly, accurate and compact solution for pressure comparison calibrations. The built-in reference sensor is changeable, several pressure ranges with one unit can be operated.

All standard pressure ranges between 0...4 psi (0...250 mbar) and 0...14500 psi (0...1000 bar) are available (other ranges, gauge and absolute, on request), also vacuum and compound ranges with certified accuracy ±0.025% f.s.. Furthermore high pressure ranges up to 8000 bar (116'000 psi) are available with certified accuracy ±0.1% f.s.

The electronic pressure calibrator LPC 300 measures pressure, voltage and current and supplies 24 VDC as source for transmitter. Calibration procedures can be pre-defined and used for calibrations on site. The LPC 300 is supplied with USB- and RS232-interfaces and is powered by a Lithium-Ion battery (rechargeable, without memory-effect).

Accuracy 0.025% FS In measuring mode, the LPC 300 shows in it's display simultaneous: reference pressure output of unit under test (if unit under test is an analogue pressure gauge, the reading pressure can be entered with the numeric keypad) deviation in selected pressure unit deviation in % of full scale value of unit under test

This results in easy checking if unit under test is within it's specification - with one view - withoud the need of manual calculations.

The LPC 300 reference sensor can be used mounted at the LPC 300 unit, or with an optional extension cable external. Examples:
