Merit Sensor J Series

The J series low pressure MEMS pressure sensing elements from Merit Sensor^TM is ideal for OEM applications, offering available pressure ranges of between 1psi and 300psi. 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 120mV (depending on the pressure range). The J series from Merit Sensor^TM products incorporate a proprietary Sentium® technology, developed to provide a best-in-class operating temperature range and superior stability.
