The 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 PC4 can be used with battery (9V E-Block) or (optional) from the mains (plug-in power supply).

The robust inductive measuring cell covers a wide pressure measuring range by means of a 1 : 5 pressure range selector. The PC4 can be delivered for 3 standard measuring ranges. Responsetime 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 hand pump is used to generate a pressure and metal bellows is used for precide adjustment.

Two integrated valves are used to vent the measuring equipment.

Application Areas:

Heating, ventilation, air conditioning, Cleanroom technology, medical technology, Filter technology, Level measurements (bubble-through measurements), Flow-velocity measurements (Pitot tube, orifice blade)
