Application area
The VEGABAR 86 is a submersible pressure transmitter for level measurement in wells, basins and open vessels. Its great flexibility throughdifferent cable and tube versions allows the instrument to be used inmany different applications.The simple connection of VEGABAR series 80 sensors as electronicdifferential pressure opens up new possibilities for measuring differential pressures.
Your benefit
- High plant availability through maximum overload and vacuum resist
- ance of the ceramic measuring cell
- Self-cleaning effect thanks to front-flush design
- Low costs for maintenance thanks to wear-free ceramic measuring
- cell
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.The sensor element with VEGABAR 86 is the CERTEC® measuringcell with excellent long-term stability and high overload resistance. Themeasuring cell is also equipped with a temperature sensor. The temperature value can be displayed via the display and adjustment moduleor processed via the signal output.
Case Studies
Municipal Wastewater Treatment · Static Pressure Measurement — Application Case
Project Background
The project covers the inlet, biological and outlet stages of a municipal plant. The work centres on Static Pressure Measurement and the core task is inferring vessel level or density from hydrostatic pressure.
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 Static Pressure Measurement cannot be specified generically — it calls for choosing range by tank height, density and pressurisation.
Solution
The Ainstru engineering team worked through the pressure range: pressure solution matched to process pressure and temperature. The configuration involves choosing range by tank height, density and pressurisation, 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 submersible mounting that avoids civil works in pit and sump retrofits.
Food & Beverage · Static Pressure Measurement — Application Case
Project Overview
The site is dosing, pasteurising, filling and CIP stages. The customer wanted Static Pressure Measurement properly configured on the existing plant, with the aim of inferring vessel level or density from hydrostatic pressure.
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 Static Pressure Measurement configuration has to involve choosing range by tank height, density and pressurisation.
Configuration
Supply and installation were organised through the pressure range: pressure solution matched to process pressure and temperature. On site this meant choosing range by tank height, density and pressurisation, checked line by line against: food-safety and hygienic design per 3-A / EHEDG.
Performance
After commissioning the outcome is submersible mounting that avoids civil works in pit and sump retrofits, and the readings are now used for process tuning.
Chemical & Pharmaceutical · Static Pressure Measurement — Application Case
Site Conditions
This is a Chemical & Pharmaceutical customer whose plant is at reactors, metering vessels and finished-product tanks. The main task was inferring vessel level or density from hydrostatic pressure.
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 range by tank height, density and pressurisation.
What We Did
We took a pressure range approach — pressure solution matched to process pressure and temperature. Delivery was built around choosing range by tank height, density and pressurisation, with point-by-point checks on: Ex certification and GMP traceability of records.
Operating Outcome
In service the system performs as intended — submersible mounting that avoids civil works in pit and sump retrofits, with routine maintenance falling noticeably.
Power & Energy · Static Pressure Measurement — Application Case
Application Context
boiler feedwater, turbine condensate and FGD/DeNOx systems is a typical Power & Energy duty. The project started from Static Pressure Measurement, focusing on inferring vessel level or density from hydrostatic pressure.
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 Static Pressure Measurement specification must therefore cover choosing range by tank height, density and pressurisation.
Delivery Approach
Delivery was handled as the pressure range — pressure solution matched to process pressure and temperature. Execution centred on choosing range by tank height, density and pressurisation, together with compliance with power-industry codes and unit availability targets.
Field Results
Operation shows the benefit clearly — submersible mounting that avoids civil works in pit and sump retrofits, with confidence in this measuring point improving markedly.
