DESCRIPTION
The Model 1620 is a fully piezoresistive silicon pressure sensor
for use in invasive blood pressure monitoring. The sensor is
designed to be used with automated assembly equipment and
can be dropped directly into a customer’s disposable blood
pressure housing. The sensor is designed to meet the
requirements as described in the Association for the
Advancement of Medical Instrumentation (AAMI) specification
for Blood Pressure Transducers.
mounted on a ceramic substrate. Thick-film resistors on the
ceramic substrate are laser-trimmed for compensation and
calibration.
an easy method of attachment to the customers assembly and
protection for the sensing element. A dielectric gel is placed
over the sensor to provide electrical and fluid isolation.
in a 10x12 element array on a ceramic substrate (120 units per
substrate). The products are shipped in anti-static shipping
containers. Performance characteristics and packaging can be
easily tailored on a special order basis to meet the requirements
of specific customers.
