1.1 Function and configuration

Output signal

The pressure transmitter D85 is an efficient instrument for hydrostatic level measurement. A dry metallic-capacitive measuring cell is used as pressure sensor element.

Pressure transmitter D85

Measuring cell: dry, metallic-capacitive Diaphragm: flush, stainless steel (Duratherm 600)

Series: flanged version

Standard application: All kind of level measurements, best suited for food processing and pharmaceutical industries and for product temperatures up to 200°C

The hydrostatic pressure of the medium effects a capacitance change in the measuring cell. This capacitance change is detected by an ASIC (Application Specific Integrated Circuit) and converted into a pressure-proportional signal by the integrated electronic module with microcontroller. Precise, high-resolution digital processing of measurement data ensures excellent technical data.

To improve reliability, the functionality of important electronic components is continuously checked, and internal parameters such as sensor value, temperature and operating voltage are closely monitored.

The output signal is transferred as a digital or analogue signal from the pressure transmitter to the signal conditioning instrument:

•analogue output signal

-unstandardised (in conjunction with VEGA signal conditioning instrument)

-4 … 20 mA standardised

•digital output signal (VBUS) for connection to a digital VEGA signal conditioning instrument (VEGAMET 514V, 515V or VEGALOG 571)
