DATA SHEETMSS100 Series
The MSS100 Series is a fully compensated pressure transducer that
is ideal for medical, pharmaceutical, and bio-processing applications thatinvolve harsh fluids.
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.

HISTORY: For over 25 years Merit Sensor has been apressure-sensor supplier to the medical-device industry.

TECHNOLOGY: Merit Sensor utilizes a piezoresistive

with Molex cable

Wheatstone bridge in a design that anodically bonds glass to achemically etched silicon diaphragm. All products are RoHS andREACH compliant.

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