Characteristic
For level measurement of liquids and corrosive media. Maximum sensor length: Cable 250 m, tube 6 m. Can be combined with any other sensor of VEGABAR Series 80 for electronic differential pressure measurement.
Application
The VEGABAR 87 is a pressure transmitter for pressure and level measurements of liquids and viscous products with higher temperatures in the chemical, food processing and pharmaceutical industry. With VEGABAR 87 it is possible to detect even smallest measuring ranges from 0.1 bar. The simple connection of VEGABAR series 80 sensors as electronic differential pressure opens new possibilities for the measurement of differential pressures.
Benefits
- Maximum reliability even with rapidly changing process temperatures
- High plant availability through vacuum-resistant version
- Very good cleanability and high chemical resistance through adapted materials
