Instrumentation specialist Impress Sensors Systems has launched a new oil free stainless steel welded pressure sensor for oxygen applications where silicon oils or elastomeric seals cannot be used.

The DMP335 is said to offer high overpressures (typically three times the nominal pressure rating) and is also suitable for mobile hydraulics and machine engineering, where pressure spikes or peaks are present.

“Oxygen is present in many process manufacturing environments, medical applications, as well as filling and bottling plants,” noted Sam Drury, sales and marketing director at Impress. “The oxygen needs to be transported safely through these processes without coming into contact with oil or other contaminated fluids, which could cause an explosion. The all stainless steel, oil free design of the DMP335 pressure sensor makes it ideal for these types of environments.”

The sensor is ATEX certified for hazardous gas and dust environments. Nominal pressures are available from 0 to 6bar up to 0 to 600bar. Permissible temperatures are rated between –40 to 125°C.
