Description

VEGAWELL S 51

 Suspended pressure transmitter for continuous liquid level measurement

    §Â  Dry, ceramic-capacitive CERTEC® measuring cell

§Â  Abrasion, shock and overpressure resistant

§Â  Integrated overvoltage protection

§Â  4 20 mA two-wire system

§Â  Narrow design with only 22 mm diameter

 

Function

The dry, ceramic measuring cell CERTEC® is the heart of

VEGAWELL S 51. The hydrostatic pressure of the liquid

column causes a capacitance change in the measuring cell

via the ceramic diaphragm. This change is converted into a

standardised 4 20 mA signal. The complete measuring cell

consists of high purity ceramic and is characterised, apart

from excellent longterm stability, by its very high overload

resistance, e.g. when lowering it from a height as it can strike

the water surface hard and the shock can initiate an offset

error.

Area of application

VEGAWELL S 51 is designed for measurement of liquids in

open vented vessels, tanks, boreholes and sumps, especially

in applications when foam is on the surface. The rugged

measuring cell and special construction means that the

sensor is largely resistant to pressure shocks that can occur

during installation.

 

It can be teamed up with VEGAMET 381 which can provide

power, a calibrated output, a display, 2 relay switch points

and fault relay.
