Medical technology: 10 things about in vivo sensor technology

Catheter pressure sensors measure the pressure of body fluids directly in the body. By eliminating the need for a buffering interface, the IntraSense allows fast response time and accurate measurement results, which can be crucial during surgical intervention.

For the handling of this extremely small sensor and the evaluation of its measurement results, you will find 10 tips for applications in medical technology hereafter.

FAQ about IntraSense

Low pressure sensor SM9235 for differential and relative pressure

These differential pressure sensors for extremely low pressures of up to 3 mbar are used in medical technology and filter control.

OEM pressure sensor SM9235 comes in a SOIC 16 housing and has a digital I2C output signal and an optional 3.3-V or 5-V supply. The AMSYS sensor is calibrated and compensated for and its accuracy can be increased by offset calibration.

MS 5849 – Chlorine resistant absolute pressure sensor

The MS5849 is a small, digital OEM sensor with a wide pressure range of 0.3 – 30 bar and high 24-bit resolution. It precisely measures absolute pressure and outputs the measured values as digital output signals via an I²C or SPI interface.

In addition, it measures temperature in a range of -40 to +110 °C and is media-protected with a chlorine-resistant gel coating.

Pressure/Flow: LME – 25 pascal digital analog sensor

The differential pressure sensors of the LME series are based on micro-flow technology and can detect low pressures in the range of 25 Pa for flow measurement of air and gases.

The sensors have a flow channel integrated into the silicon, have a high long-term stability and are also suitable for manifold mounting with an O-ring.
