VEGA Transmitters. Process Pressure Measurement.

VEGA Transmitters : Process Pressure Measurement

Process pressure measurement transmitters and sensors are used to measure the pressure of liquids, gases and vapours in pipes or closed vessels or containers – the pressure of the measured medium acts on a pressure measuring cell, which converts it into an electronic signal.

VEGA process pressure transmitters and sensors are specified for detecting the relative or absolute pressure in applications with condensation or rapid temperature changes – this includes potentially explosive atmospheres in classified hazardous areas.

Hazardous Area Zones

Hazardous Area Zones

What is Hazardous Area Zone 1?

        • Zone 1 Hazardous Area – a potentially explosive atmosphere in which an explosive liquid or gas atmosphere is likely to occur in normal operation. Although not officially quantified according to IECEx or ATEX but commonly accepted by hazardous area industries as being prevalent for more than 10, but less than 1000 h/yr.

What is Hazardous Area Zone 2?

          • Zone 2 Hazardous Area – a potentially explosive atmosphere in which an explosive liquid or gas atmosphere is not likely to occur in normal operation and if it occurs will exist only for a short time. “Short time” is not officially quantified according to IECEx or ATEX but commonly accepted by hazardous area industries as being prevalent for less than 10h/yr.

Should you require any technical support to select and purchase the correct hazardous area transmitter or sensor, please contact T&D.

VEGA VEGABAR process pressure gauges and transmitters measure the pressure and level of liquids, gases and vapours in non-hazardous and hazardous areas – designed for use in chemically aggressive liquids as well as in explosive atmospheres aor hygienic areas. VEGA process pressure transmitters are ideal for detecting relative or absolute pressure in applications with condensation or rapid temperature changes and can also measure the temperature of the medium.
