LP Series – Analog
DATA SHEET
LP Series - Analog
is a surface mountable pressure sensor package with a
compensated analog output suitable for
ultra-low pressure sensing applications.
COMPANY:
Merit Sensor is a leader in piezoresistive
pressure sensing and partners with clients to create high
performing solutions for a variety of applications and industries.
SENTIUM:
Merit Sensor products incorporate a proprietary
Sentium
®
technology developed to provide a best-in-class operating
temperature range (-40°C to 85°C) and superior stability.
TECHNOLOGY:
Merit Sensor utilizes a piezoresistive Wheatstone
bridge in a design that anodically bonds glass to a chemically etched
silicon diaphragm. All products are RoHS compliant.
CAPABILITIES:
Merit Sensor designs, engineers, fabricates, dices,
assembles, tests, sells and services die and packaged products from
a state-of-the-art facility near Salt Lake City, Utah
