Uncalibrated Intrasense

The IntraSense series absolute pressure sensors are designed to fit into a 1-French hypo tube. The sensor comes pre-attached to cabling, simplifying the connection for the end user. The fully encapsulated electronics allow the device to be used without additional gel or encapsulant. This sensor compares pressure in vivo to an onboard vacuum cavity for reference to an absolute standard. It delivers accurate and stable pressure for acute procedures in the clinically useful range of -300mmHg to +500mmHg (460mmHg to 1260mmHg absolute) and from 10°C to 60°C. The output is stable in 37°C saline, with typical drifts of <2mmHg absolute maximum per 24 hours. The device is available either as a sensor plus cable, or with an optional 4-pin PCB board attached to the proximal end.
