IntraSense TM Series 1-French Wire-Connected Pressure Sensor SMI-1A-48-180-AAUU FEATURES Miniature size: 750 µm 220 µm 75 µm Fits within 1-French catheter products Typical drift <1 mmhg/hour drift in 37 C saline Encapsulated A.W.G. 48 copper trifilarconnection for ease of integration Meets AAMI specification guidelines RoHS and REACH Compliant Biocompatible materials DESCRIPTION The IntraSense TM series are absolute pressure sensors designed to fit into a 1-French hypo tube. The attached wire simplifies the connection for the end user, and for disposable procedures, additional gel or encapsulation is not required. This absolute die delivers accurate and stable pressure for acute procedures in the clinically useful range of -300 mmhg to 300mmHg. The output is stable in 37 C saline. The proximal end of the trifilar is terminated in 2cm stripped bare copper wires. Length of wire is per customer requirements. This device is intended for single use.
