Application area
The VEGABAR 28 is a universally applicable pressure sensor withswitching function and ceramic measuring cell. It is used for measuringgases, vapours and liquids. Even with high requirements for robustness and hygiene, the device records the measured values with highaccuracy.The optional universal connection for hygienic adapters reduces theinstallation effort and stockkeeping.
Your benefit
- High plant availability through maximum overload and vacuum resist
- ance of the ceramic measuring cell
- Coloured 360° status indication
- Convenient wireless setup and diagnostics with smartphone via
- Bluetooth
- Easy integration into control systems due to a variety of connection
- technologies
Function
The heart of the pressure transmitter is the pressure measuring celltransforming the pressure into an electrical signal. This pressure-dependent signal is convereted by the integrated electronics into astandardized output signal.Sensor element with VEGABAR 28 is the ceramic CERTEC® measuringcell with excellent long-term stability and high overload resistance.
Case Studies
Municipal Wastewater Treatment · VEGA — Stock Configuration Case
Project Background
The project covers the inlet, biological and outlet stages of a municipal plant. The work centres on VEGA and the core task is covering level and pressure measurement with VEGA instruments.
Operating Challenges
The medium and duty are characterised by high solids and corrosive fractions, with large diurnal flow swings, and effluent parameters drift and probes foul with sludge and biofilm. So VEGA cannot be specified generically — it calls for choosing radar or pressure families by dust, vapour and corrosion.
Solution
The Ainstru engineering team worked through the stock channel: configuring from stock and delivered quickly. The configuration involves choosing radar or pressure families by dust, vapour and corrosion, with these requirements in view: stable compliance with Grade 1A discharge limits and online data reporting.
Results
Since start-up the system has run steadily; the practical result is friendly commissioning software that shortens start-up.
Food & Beverage · VEGA — Stock Configuration Case
Project Overview
The site is dosing, pasteurising, filling and CIP stages. The customer wanted VEGA properly configured on the existing plant, with the aim of covering level and pressure measurement with VEGA instruments.
Technical Challenges
What actually causes trouble is syrups, dairy and beverages that scale easily, under strict hygienic requirements, and frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. All of this means the VEGA configuration has to involve choosing radar or pressure families by dust, vapour and corrosion.
Configuration
Supply and installation were organised through the stock channel: configuring from stock and delivered quickly. On site this meant choosing radar or pressure families by dust, vapour and corrosion, checked line by line against: food-safety and hygienic design per 3-A / EHEDG.
Performance
After commissioning the outcome is friendly commissioning software that shortens start-up, and the readings are now used for process tuning.
Chemical & Pharmaceutical · VEGA — Stock Configuration Case
Site Conditions
This is a Chemical & Pharmaceutical customer whose plant is at reactors, metering vessels and finished-product tanks. The main task was covering level and pressure measurement with VEGA instruments.
The Problem
The difficulty lies in highly corrosive media with solvents and crystallisation, partly in explosive atmospheres; at the same time corrosion plus Ex protection shortens instrument life and makes downtime costly. Specification therefore means choosing radar or pressure families by dust, vapour and corrosion.
What We Did
We took a stock channel approach — configuring from stock and delivered quickly. Delivery was built around choosing radar or pressure families by dust, vapour and corrosion, with point-by-point checks on: Ex certification and GMP traceability of records.
Operating Outcome
In service the system performs as intended — friendly commissioning software that shortens start-up, with routine maintenance falling noticeably.
Power & Energy · VEGA — Stock Configuration Case
Application Context
boiler feedwater, turbine condensate and FGD/DeNOx systems is a typical Power & Energy duty. The project started from VEGA, focusing on covering level and pressure measurement with VEGA instruments.
Process Constraints
drift under high temperature and pressure, with very costly unplanned outages, and high temperature and pressure with both steam and saline water only amplify it. The VEGA specification must therefore cover choosing radar or pressure families by dust, vapour and corrosion.
Delivery Approach
Delivery was handled as the stock channel — configuring from stock and delivered quickly. Execution centred on choosing radar or pressure families by dust, vapour and corrosion, together with compliance with power-industry codes and unit availability targets.
Field Results
Operation shows the benefit clearly — friendly commissioning software that shortens start-up, with confidence in this measuring point improving markedly.
