DATA SHEETSMD Series
The SMD Series is a surface-mountable pressure monitoring device
suitable for low to medium pressure applications.
COMPANY: Merit Sensor is a leader in piezoresistive
pressure sensing and partners with clients to create highperforming solutions for a variety of applications and industries.

SENTIUM: Merit Sensor products incorporate a proprietary
Sentium® technology developed to provide a best-in-classoperating temperature range (-40°C to 85°C) and superior stability.

TECHNOLOGY: Merit Sensor utilizes apiezoresistive Wheatstone bridge in a designthat anodically bonds glass to a chemicallyetched silicon diaphragm. All products
are RoHS compliant.

CAPABILITIES: Merit Sensor designs, engineers, fabricates,dices, assembles and tests all products from a state-of-the-art
facility near Salt Lake City, Utah.
