Offered with a 0 to 15 psia range and with 200 mV full-scale output (with 5 Vdc sensor excitation), the highly compact Endevco® model 40931 measures just 1.65 mm long by 1.2 mm wide by 0.4 mm tall. A uniquely sculptured silicon diaphragm design provides high sensitivity, high overpressure capability and a combined 0.5% non-linearity, non-repeatability and hysteresis specification, making it one of the most accurate pressure transducers of its size and type on the market today. Four connection pads allow for the sensor to be “flip chip” mounted to a circuit or substrate using conductive epoxy. The MEMS pressure sensing element, located on the top of the sensor package, enables surface mounting and serves as the active sensing element for absolute pressure measurements.
All sensing elements for the Endevco® model 40931 are machined in-house at Meggitt’s own ISO9001 certified MEMS facility in Sunnyvale, California, USA, where vertically integrated manufacturing processes allow for full control of product quality, from component through to finished product.
