Safety information

Please read this manual carefully, and also take note of country-specific installation standards (e.g. the VDE regulations in Germany) as well as all prevailing safety regulations and accident prevention rules.

For safety and warranty reasons, any internal work on the instruments, apart from that involved in normal installation and electrical connection, must be carried out only by qualified VEGA personnel.

Note Ex area

Please note the attached safety instructions containing important information on installation and operation in Ex areas.

These safety instructions are part of the operating instructions and come with the Ex approved instruments.

1.1 Function and configuration

Pressure transmitters D86 and D87 are instruments for hydrostatic level measurement.

Pressure transmitter D86

Measuring cell: dry, ceramic-capacitive Diaphragm: flush, sapphire-ceramic® Series: suspension version

Standard application: Level and gauge measurements in water/sewage water, flumes, basins, deep wells, vessels and tanks

Pressure transmitter D87

Measuring cell: dry, metallic-capacitive Diaphragm: Duratherm 600

Series: suspension version

Standard application: Level and gauge measurements in water/sewage water, flumes, basins, deep wells, vessels and tanks

The pressure effects a capacitance change on 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.

Output signal

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)
