Specification sheet Two-wire 4 … 20 mA Pressure sensor with metallic measuring cell Technical data Measuring ranges -1 … +100 bar/-100 … +10 MPa (-14.5 … +1450 psig) Smallest measuring range 0.4 bar/40 kPa (5 psig) Deviation < 0.5 % Output signal 4 … 20 mA Process fitting Thread from G½, ½ NPT Process temperature -40 … +100 °C (-40 … +212 °F) Ambient, storage and -40 … +70 °C (-40 … +140 °F) transport temperature Operating voltage 12 … 35 V DC Materials The wetted parts of the instrument such as process fitting and measuring diaphragm are made of 316L. The process seal is made of Klingersil C-4400. You will find a complete overview of the available materials and seals in the "Configurator" at www.vega.com and "VEGA Tools". Application area The pressure transmitter VEGABAR 19 ensures reliable plant operation and improved process safety by accurately measuring the measured values of gases, vapours and liquids also under high pressures. Your benefit • Low-cost version with very small mounting dimensions Housing versions The housing is equipped with plug connectors acc. to ISO 4400 or M12 x 1. It is available with protection ratings up to IP66/IP67. Electronics versions • Universal use thanks to completely welded metallic measuring cell The instrument has a 4 … 20 mA signal output. Electrical connection The heart of the pressure transmitter is the pressure measuring cell transforming the pressure into an electrical signal. This pressuredependent signal is convereted by the integrated electronics into a standardized output signal. The metallic measuring cell is completely welded and has a piezoresistive sensor element with internal transmission fluid.
