The wide range of models and configurations offer an extensive choice of cost-effective solutions from low-cost, high-volume OEM production to high-performance research and development.
Featuring thin-film and diffused-silicon sensing elements, the piezo-resistive sensing technology is inherently accurate, small and robust with stainless-steel body construction.
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 up to 0 to 4000 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 from 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), gauge (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. Special intrinsically-safe ATEX / EX approved versions are also available for use in Zone 0 and 1 hazardous areas.
This extensive pressure sensor range complements the existing range of Curtiss-Wright position sensors from the Penny & Giles brand family, and offers existing and new customers a wider choice of sensing solutions from one supplier.
