Impress Sensors & Systems has recently launched 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 sanitised for medical applications. The sensors are completely de-greased before despatch to the customer.
The sensors are ATEX certified (intrinsically safe) for hazardous gas and dust environments (Zone 0 and Zone 20). Nominal pressures are available from 0… 6 bar up to 0… 600 bar. Permissible temperatures are from-40°C to 125°C. Output signal is either 2-wire – 4 to 20mA, or 3-wire – 0 to 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°.
