Blood pressure monitoring pressure sensor

The Model HT162 is a fully pizoresistive 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 lasertrimmed for compensation and calibration.A plastic cap is attached to the ceramic substrate to provide an easy method of attachment to thecustomers assembly and protection for the sensing element.A dielectric gel isplaced over the sensor to provide electrical and fluid isolation.
