AdSem’s High Quality Catheter NTC Thermistors

AdSem tiny Ge thermistorsPalo Alto CA, USA — AdSem, Inc., the pioneers and developers of unique Silicon (Si) and Germanium (Ge) Negative Temperature Coefficient (NTC) thermistor technology has announced the start of industrial production of unique medical thermistors.

The very small size of the sensitive elements, as small as 0.25 mm x 0.25 mm (0.10″ X 0.10″) in crossection) with 2 meter long leads makes them attractive for catheter uses or applications where the sensor needs to travel a long distance through a narrow openings to the test site in high humidity/water environment, like the human body.

Both the Si and Ge catheter thermistors developed by AdSem are chemically stable in water (as opposed to standard ceramic thermistors) and have significantly higher thermo-sensitivity (-5.0 %/degree for Ge and -7.3%/degree for Si at room temperature) than ceramic thermistors or any other temperature measuring devices.

Their extremely small size and low heat capacity means they respond quickly due to their tiny net thermal mass.

AdSem’s NTC thermistors are intended for highly reliable and accurate temperature measurements inside a human body with the fastest response for a small temperature change.

Si and Ge catheter thermistors are produced both for wide temperature range applications in range from -70??C to +80??C and also for narrow temperature range (a few degrees or even a few tenth of degree).

The catheter thermistors are available immediately for temperature sensor users.
