Pressure sensors for industrial applications
Curtiss-Wright’s range of robust pressure sensors are designed for pressure sensing applications for industrial applications such as factory automation, process control, automotive and specialty vehicles, hydraulics, pneumatics and environmental systems. 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. 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. 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.
