DATA SHEETBP Series

Merit Sensor is based in Salt Lake City, Utah

The Merit Sensor Blood Pressure sensor is ideal for low cost, high-volume,
disposable medical applications including blood pressure monitoring. The BP
Series sensor is passively compensated (which reduces temperature effects),
is protected by a dielectric gel, and can easily be installed into a customer’spressure device housing.
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.
Design, engineering and manufacturing of Merit Sensor products
takes place in state-of-the-art wafer fabrication facility in Utah, US.

TECHNOLOGY: Merit Sensor utilizes a piezoresistive
Wheatstone bridge with a chemically etched silicondiaphragm. All products are RoHS compliant.

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

4. Normalized offset/bridge voltage – 8 hours after 20 second warm-up.
5. Previously qualified, not tested in production.
6. Combined effect of sensitivity, repeatability, nonlinearity and hysteresis errors.
7. Sterilization performed by customer.
8. A voltage of 1,500 Vrms was applied across the dielectric gel while the gel was being monitored for dielectric breakdown. No transducers demonstrated
dielectric breakdown, indicating that the transducers will continue to protect the patient from electric current up to the designated voltage.
9. The transducer shall meet the requirements for all parameters in the specification when operated at atmospheric pressure: 425 to 850 torr (8.22 to 16.44 psi).
