Pressure-measuring devices for hydrogen
Hydrogen is considered a difficult medium because its particularly small molecules can penetrate even stainless steel and also damage a material’s structure, causing embrittlement or cracks. It is therefore extremely important that measuring devices for H2 applications are made of the right materials. This company has developed several series of pressure transmitters that can be used in both standardized and application-defined H2 processes. The measuring instruments of the Pascal CV4 (photo) and Pascal Ci4 series, as well as Compact CA16, cover a measuring range between –1 and 1,050 bars, depending on the capabilities of the individual pressure transmitter, can be used in temperatures down to –40°C and are also certified with Ex- protection and some with SIL. — Labom Mess- und Regeltechnik GmbH, Hude, Germany
