VEGA

During the initial development of plics® instruments, a special emphasis is placed on reducing a sensors running costs. VEGA’s goal is to meet the requirements of a simple operation, stable life cycle management and comprehensive instrument integration.

VEGA provide a cross-industry combination of trend-setting products and services through commitment, knowledge and experience.

Reliable operation

Extensive quality tests such as EMC, high voltage and vibration tests ensure that the sensors meet the stringent requirements and reliability demands of the many industries it is used in.

The sensor as service provider

VEGA sensors are well equipped for today's increasing demands on diagnosis, service and maintenance. All asset management information for preventative maintenance meets the requirements of Namur NE 107 or VDI/VDE 2650. Error messages in clear, readable text allow detailed, targeted diagnosis.

With level and pressure sensors, measurement can be strongly influenced by the process conditions. VEGA sensors have several memories reserved for diagnostic purposes, where the data are retained even in the event of a power interruption:

Event memory

The event memories in VEGA instruments allow continuous tracking of changes in the sensor and in the process. If servicing is required, these data can be read out and analyzed with a PC (with DTM).
Up to 500 events with time stamp are automatically stored non-deletably in the sensor. Each entry contains the date/time, event type, event description and value.
Event types are, for example:

  • Change of a parameter
  • On/off switching times
  • Status messages
  • Error messages

Measurement data memory

A memory area reserved solely for diagnostic purposes keeps track of up to 100,000 readings with date and time.
All instruments have a real-time clock that allows data storage with time stamp and an input of time information during the final adjustment of the sensors.
With these data, a comparison between the sensor recording and the action in the ongoing process is possible.

Echo curve memory

By means of the function "Echo curve memory",  the echo curve of instruments using a transit time method (radar, TDR) can be stored as a reference at the time of setup. This is generally recommended, and is absolutely required for using the asset management functions. Up to 10 echo curves can also be recorded during normal operation.

With the adjustment software PACTware and a PC, the high-resolution echo curve can be displayed and recorded in order to detect signal changes throughout the operating period.
To make a comparison, the echo curve recorded at the time of setup can be displayed superimposed on the current echo curve.
