	3.2 Principle of operation
Application area	VEGABAR 18 is suitable for applications in virtually all industries. It is
	used for the measurement of the following pressure types.
	• Gauge pressure
Measured products	Measured products are gases, vapours and liquids.
Measured variables	The VEGABAR 18 is suitable for the measurement of the following
	process variables:
	• Process pressure

Fig. 3: Process pressure measurement VEGABAR 18

Measuring system pressure

The sensor element is the Mini-CERTEC® measuring cell with robust ceramic diaphragm.The process pressure deflects the ceramic diaphragm and causes a capacitance change in the measuring cell. This capacitance change is converted into an electrical signal and outputted as measured value via the output signal.

	2	Glass joint
	3	Base element
Pressure types	Relative pressure: the measuring cell is open to the atmosphere.
	The ambient pressure is detected in the measuring cell and compen-
	sated.It thus has no influence on the measured value.
Recessed installation	The recessed installation is particularly suitable for applications with
	gases, vapours and clear liquids. The measuring cell seal is posi-
	tioned laterally as well as in addition in front.

	3.4 Packaging, transport and storage
Packaging	Your instrument was protected by packaging during transport. Its
	capacity to handle normal loads during transport is assured by a test
	based on ISO 4180.
	The packaging consists of environment-friendly, recyclable card-
	board. For special versions, PE foam or PE foil is also used. Dispose
	of the packaging material via specialised recycling companies.
Transport	Transport must be carried out in due consideration of the notes on the
	transport packaging. Nonobservance of these instructions can cause
	damage to the device.
Transport inspection	The delivery must be checked for completeness and possible transit
	damage immediately at receipt. Ascertained transit damage or con-
	cealed defects must be appropriately dealt with.
