Pressure transducer model 1620
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.
The pressure sensor consists of a pressure sensing element mounted on a ceramic substrate. Thickfilm resistors on the ceramic substrate are laser trimmed for compensation and calibration.
A plastic cap is attached to the ceramic substrate to provide 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.
The Model 1620 pressure sensors are batch manufactured in a 10x12 element array on a ceramic substrate (120 units per substrate). The products are shipped in anti-static shipping containers. They can also be shipped on a tape and reel.
Performance characteristics and packaging can be easily tailored on a special order basis to meet the requirements of specific customers.
