Oil-free pressure sensor for O2 and mobile hydraulics systemsImpress Sensors & Systems Ltd is launching a new oil-free stainless steel welded pressure sensor for oxygen applications, where silicon oils or elastomeric seals cannot be used. The sensors offer high overpressures (typically three times the nominal pressure rating) and so are also suitable for mobile hydraulics and machine engineering, where pressure spikes or peaks are present.

The new DMP335 has no O-ring seals, which means the sensor is easier to keep clean and sanitise for medical applications. The sensors are completely de-greased before despatch to the customer.

Sam Drury, Sales & Marketing Director at Impress Sensors & Systems, comments: “Oxygen is present in many process manufacturing environments, medical applications, as well as filling and bottling plants. 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.”

DMP335 sensors are ATEX-certified (intrinsically safe) for hazardous gas and dust environments (Zone 0 and Zone 20). Nominal pressures are available from 0… 6bar up to 0… 600bar. Permissible temperatures are from -40degC to +125degC. Output signal is either 2-wire: 4–20mA, or 3-wire: 0–10V.

A version of the sensor is also available with 4-digit LED display and one, two or four PNP contacts. The digital display is configurable and can be rotated through 180 degrees.
