New robust pressure sensors introduced by Curtiss-Wright

0

Curtiss-Wright’s industrial division has launched a new range of robust pressure sensors.

Thin-film polysilicon resistors are applied to a stainless-steel diaphragm that deflects under pressure from the measured media, providing a varying voltage that can be converted into other electrical outputs. Benefits include long-term stability exceeding 0.1% per annum and excellent compatibility with a wide range of gas and fluid media, operating at ranges of 0 to 4,000 bar.

The sensing element features a silicon diaphragm into which pressure-dependent resistors have been diffused. The technology is a cost-effective solution for high-volume manufacturing, and especially suited to large-batch production. This technology is more suited to non-aggressive gas and fluid media, operating at ranges of 0.1 to 40 bar.

Both technologies are integrated into stainless-steel housings with a choice of pressure port and electrical connection options. This enables it to be readily adapted into numerous different sensor configurations to suit specific customer needs.

Pressure modes include absolute (relative to a vacuum), gage (relative to ambient atmospheric), differential and sealed reference options, with measurement accuracies nominally 0.5% at room temperature, with an option to 0.1% in the high precision range.
