VEGA LEVEL SENSOR – VEGAFLEX 81 FEATURES

FunctioN

High frequency microwave pulses are coupled onto a cable or rod and guided along the probe. The pulse is reflected by the product surface. The time from emission to reception of the signals is proportional to the level in the vessel.

Materials

The wetted parts of the instrument are made of stainless steel and the instrument seal is made of one of the following FKM, FFKM or EPDM.

Housings

The level sensor housings are available as double chamber version in plastic, stainless steel or aluminium with protection ratings up to IP66/IP67.

ELECTRONICS

VEGA sensors are available in different electronics versions. Apart from the two-wire electronics with 4 … 20 mA/HART, there are two pure digital versions with Profibus PA and Foundation Fieldbus possible as well as one version for connection to a signal conditioning instrument.

VEGA LEVEL SENSORS – veGAFLEX

VEGAFLEX level sensors provide level measurement for bulk solids, liquids and separation layers (interfaces). In guided wave radar level measurement, microwave pulses are conducted along a cable or rod probe and reflected by the product surface. The measuring probe of the TDR sensor ensures that the signal reaches the medium without disruption. VEGA is a global manufacturer of process and hazardous area instrumentation.

Thorne & Derrick provide Process Measurement and Instrumentation systems for level measurement, flow measurement, temperature measurement and pressure measurement.

Thorne & Derrick can provide expert technical advice, specification guidance and competitive quotations for VEGA sensors from stock. Contact us for support on industrial and hazardous area flow measurement.
