Description
The L series silicon MEMS piezoresistive pressure sensor from Merit SensorTM is ideal for ultra-low pressure applications, offering pressure ranges from 0.15 to 1psi (1 to 6.89 kPa 10 to 68.95 mbar). The sensors utilise a piezoresistive Wheatstone bridge in a design that anodically bonds glass to a chemically etched silicon diaphragm. Merit Sensor products incorporate a proprietary Sentium® technology, developed to provide an exceptional operating temperature range of -40°C to +150°C while still achieving superior stability. The L Series offers full-scale output ranges from 30mV to 60mv (at 5V excitation, depending on the pressure range) with additional outputs being available upon request.
