Description

VEGA Pressure Sensor With Switching VEGABAR 38

Pressure sensors
VEGABAR 18, 19
VEGABAR 28, 29
VEGABAR 38, 39

The sensor element is the Mini-CERTEC® measuring cell with a 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. A temperature sensor in the electronics of the Mini-CERTEC® measuring cell measures the current process temperature. The temperature value is
output via Bluetooth or the display.

VEGABAR 19, 29, 39
The process pressure acts on the sensor element via the metallic process diaphragm. The process pressure causes a resistance change which is converted into a corresponding output signal and output as
measured value.Measuring ranges up to 100 bar: piezoresistive sensor element with internal transmission liquid is used.

Electronics – Two-wire 4 … 20 mA
Voltage supply
Power the instrument via an energy-limited circuit (power max. 100 W)
acc. to IEC 61010-1.
Specifications of the voltage supply:
• Operating voltage
–– 12 … 35 V DC • Permissible residual ripple
–– for UN 12 V DC (12 V < UB < 18 V): ≤ 0,7 Veff (16 … 400 Hz)
–– for UN 24 V DC (18 V < UB < 35 V): ≤ 1,0 Veff (16 … 400 Hz)
Keep in mind the following additional factors that influence the operating
voltage:
• Lower output voltage of the power supply unit under nominal load
(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault signal) • Influence of additional instruments in the circuit (see load values in
chapter ” Technical data” of the operating instructions of the respective
instrument)
