DATA SHEETPMD Series
The PMD Series is a thru-hole mountablepressure monitoring device suitable forlow 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 and superior stability.

PMD Series Part Number Configurator

PMDX-XXX -X0X

TECHNOLOGY: Merit Sensor utilizes a piezoresistiveWheatstone bridge in a design that anodically bonds glass
to a chemically etched silicon diaphragm. All products
are RoHS compliant.

Constraint
A = Absolute
G = Gage

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