Differential Pressure Transmitter - VEGADIF 85

The VEGADIF 85 differential pressure transmitter is ideal for measuring the differential pressure between two electrolyte tanks and is also suitable for level measurement of liquid hydrogen.
An optional gold-coated diaphragm minimizes hydrogen diffusion for long-term stability.
Its robust metallic measuring cell ensures reliable pressure measurement with a maximum measuring range of up to 40 bar.
A diaphragm seal attachment enables dependable measurement even with media at extreme temperatures.
VEGA pressure sensors precisely measure the pressure of hydrogen gas in electrolysers, vessels, pipelines, and other systems.
They provide long-term stable performance and are especially easy to set up and operate.
