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.

1.1 Function and configuration

Function

VEGADIF 34 … 51 differential pressure transmitters are an efficient, modular instrument series for differential pressure, level and flow measurement.

The sensor element of VEGADIF 34 and 44 is a single-chamber ceramic measuring cell. It consists of a disk-shaped ceramic body with ceramic diaphragms on both sides. Depending on the acting pressures, the diaphragms move in or out and the measuring capacitances change. The difference of the individual capacitances is reciprocally proportional to the difference of the pressures.

The sensor element of VEGADIF 35, 45 and 51 is a silicon plate with pressure sensitive resistors. The differential pressure to be measured is received via separating diaphragms and transmitted to the sensor element via incompressible oil (silicone oil or inert oil). The silicon plate moves according to the differential pressure. The values of the resistors change (piezoresistive principle).

The capacitance or resistance values are detected by the integrated electronics, processed in the microcomputer and converted into a 4 … 20 mA output signal. This output signal is proportional to the difference of the pressures. Precise, digital processing of measured data with maximum resolution ensures excellent technical data and accuracy.

The external power supply is provided via a separate supply instrument, e.g.:

- power supply unit (e.g. VEGASTAB 690)

- processing unit with integrated direct voltage source (e.g. active PLC input)

- VEGAMET series 500 or 600 signal conditioning instrument, VEGALOG 571 processing system or VEGADIS 371 indicating instrument

Configuration

Each VEGADIF consists of only two modular components:

- the electronics housing

- the measuring cell housing.

Sensor-specific data are permanently stored in an ASIC in the sensor. Hence the measuring cell modules can be exchanged, e.g. ceramic for silicon and vice versa. The electronics can be exchanged, e.g. from 4 … 20 mA standard to 4 … 20 mA with HART® communication protocol, without dismounting the transmitter.

The electronics in the pressure transmitter requires a power supply of 11.5 … 45 V DC.
