The IntraSense series pressure sensors are designed to fit into a 1-French hypo tube or to be mounted to a housing. The pre-attached, encapsulated wire simplifies the connection for the end user. Additional gel or encapsulation is not required after the sensor is mounted.


This absolute die delivers accurate and stable pressure for acute procedures in the clinically useful range of -300 mmHg to +300mmHg. Wider pressure ranges are available for specialized applications. This device delivers high stability in both air and 37°C saline.


A light-shielded version is also available with the IntraSenseTM SMI-1B Series. The light shielded surface reduces the sensitivity to the effects of light. This features enables accurate pressure sensing in medical devices with built-in light eg. endoscopes.


The proximal end of the trifilar is terminated in 2cm stripped bare copper wires. Length of wire is per customer requirements.


SMI can support custom-calibrated devices to fit into specific pieces of equipment.
