Description

LR-Cal PC4 Description

The LR-Cal PC4 is an appliance for verification and calibration of pressure sensors, pressure gauges, as well as pressure switches for low pressures. The combination pressure measuring unit and pressure generator allows a variety of applications in the laboratory as well as in the field.

The electronic pressure calibrator LR-Cal PC4 can be used with supplied 9V battery or from the supplied mains power supply. The robust inductive measuring cell covers a wide pressure measuring range by means of a 1 : 5 pressure range selector. The calibrator can be delivered for 3 standard measuring ranges. Response time of the measuring signal can be selected for 3 steps. The pressure is displayed on a high contrast LC display with 12.5 mm characters. An analogue output is available on request. For greater volumes an integrated handpump is used to generate a pressure and metal bellows is used for precise adjustments. Two integrated valves are used to vent the measuring equipment.
