Merit Sensor AP301 Series

Merit Sensor AP301 Series

The AP301 series medium pressure MEMS sensing elements from Merit SensorTM is ideal for OEM applications, offering available pressure ranges of between 100psi and 1000psi. The sensors utilise a piezoresistive Wheatstone bridge in a design that anodically bonds glass to a chemically etched silicon diaphragm. This pressure sensor series offers an operating temperature of −40°C to +150°C and a full scale output range of either 150mV or 175mv (depending on the pressure range). The AP301 series from Merit SensorTM products incorporate a proprietary Sentium® technology, developed to provide a best-in-class operating temperature range and superior stability.
