IntraSense Calibrated

IntraSense Calibrated sensors are designed for in-vivo sensing. The absolute pressure sensor fits into a 1-French hypo tube or can be mounted to a housing. The attached wire simplifies the connection for the end user; for many applications, 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 +500 mmHg. The output is stable in both air and 37°C saline, with a drift of less than 1 mmHg over twelve hours in 37°C saline.

The calibrated device is delivered with a PCB on the proximal end with a 5-pin connector offering fully temperature-compensated output, with pressure and temperature ranges calibrated to customer requirements. The sensor delivers both digital and analog output signals with the output accuracy of +/- 1.5 %FS.


Length of wire is per customer requirements.


A light-shielded version is also available with the IntraSense Calibrated SMI-1B Series. The light shielded surface reduces the sensitivity to the effects of light. This option facilitates the use for medical devices with built-in light, eg. Endoscopes, or in environments, such as ocular, where ambient light could affect sensor readings.


With its miniature size and compatibility high tortuosity IntraSense Calibrated can reach difficult-to-access areas in the human anatomy and deliver accurate pressure measurements.
