Endevco model 8530C series from Meggitt Sensing Systems is offered in 15-, 50-, and 100-psi (1-, 3-, and 7-bar) ranges with corresponding high resonance frequencies of 180, 320, and 500 kHz. The series (part of Meggitt's InStock program) offers 225 mV full-scale output and a nonlinearity specification of less than 1%. Transducers are rugged to 20,000 g. Other features include a four-arm strain gage bridge diffused to a sculpted silicon diaphragm for sensitivity and frequency response as well as a compact 3.86-mm (0.15-in), 2-3 g (0.08-oz) package. Volume is both evacuated and glass-sealed to provide absolute reference. Temperature is compensated from -18 to +93°C (0° to +200°F), and the series is suitable for the testing of automotive door panel crash conditions and vehicle transmission performance.
