EC79/2009, EC406/2010 and Automotive E1 type approvals: New pressure sensors from Variohm EuroSensor have type-approval for hydrogen generation, storage and transport


With the launch of its new EPT31H2 and SMO31H2 series pressure sensors, Variohm EuroSensor has attained the European type-approval standards required for safe measurement and monitoring on high-pressure hydrogen generation, storage and transportation systems up to 700 bar - as well as fulfil automotive industry approval for the lower pressure ranges required for hydrogen fuel-cell powered vehicles. Both new H2 model lines meet the EC79/2009 and EC406/2010 type-approvals for hydrogen processing and storage systems whilst the SMO31H2 also has European E1 automotive type-approval making it suitable for mobile pressure monitoring applications on cars, buses and trucks etc.

The EPT31H2 and SMO31H2 pressure sensors are based upon well-proven measurement technology with a piezo-resistive sensing element and ASIC circuitry encased in a fully sealed all-stainless steel housing. They feature IP67 protection class or optional IP69K for maximum durability in a silicon-free design with no internal O-rings. With additional EMI/RFI protection, low static and thermal errors and high resistance to shock and vibration across an operational temperature range up to up to 125°C , the H2 models deliver high accuracy, linearity and repeatability through several pressure range options from 1.0 bar to 1000 bar for gauge or optionally vacuum measurement (EC79 approval is limited to 700 bar for both model lines).

Output options available are 4…20 mA or 0.5…4.5 V from a 5 V DC supply. A choice of pressure port configurations match various pressure range options. Electrical interfacing is a 600 mm cable with free ends, Metri-Pack connector or M12x1 round connector.

Both new H2 model lines are covered new datasheets EPT31H2, SMO31H2 - available from Variohm EuroSensor’s website at www.variohm.com.
