VEGABAR 87

Submersible pressure transmitter with metallic measuring cell

Application area

Liquids

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.

Your benefit

• Maximum reliability even with rapidly changing process temperatures
• High plant availability through vacuum-resistant version

Pressure transmitter for viscous media, even at high process temperatures

The hydrostatic submersible pressure sensor VEGABAR 87 with metallic measuring cell measures the level of liquids and viscous media with high process temperatures (high temperature). 
The robust mechanical configuration of the metallic measuring cell protects the sensor in the demanding measuring tasks found in different industries, e.g. 

• chemically stable level measurement in ultrapure water 
• water level measurement with two hydrostatic pressure sensors for lock control 
• Maintenance-free level measurement in waste water shafts
