Miniature Medical Temp Sensors

Fast, accurate and reliable.  These are just some of the key features that, as engineers, you will look for when sourcing temperature sensors for your medical devices. ATC Semitec offer a wide range of thermal components ideal for sensing temperature – whether non-contact, surface or intravenously.

Whilst not at the front-line of ventilator manufacturing, ATC Semitec are proud to be supporting our customers in their manufacture of equipment which is being supplied to the NHS, at this difficult time.

Thermistors from our innovative suppliers, are already used in brand leading thermometers, catheters and emerging healthcare products such as surface patch glucose monitorsOne of our latest innovations is the F-micro miniature thermistor sensor which was developed for use in catheter applications e.g. ablation catheters.

Utilising smaller and smaller FT thin-film thermistor, the F-micro can now be supplied in tubes as small as 0.28mm with a time constant as fast as 20ms.  With even further innovation, ever smaller sensors will be available for future applications allowing very accurate temperature measurement where it wasn’t previously possible.

Semitec’s JT ultra-thin thermistor is increasingly being used within medical devices, due to its exceptionally fast response times and flexible film technology. Products such as minimally-invasive glucose monitors and other wearable applications benefit from the JT’s neat flexible format.

These 3 products provide an insight into how our products are supporting the NHS in many different ways:

ATC Semitec SP High Accuracy Bead NTC

A small, fast, cost effective and interchangeable NTC, used in clinical instruments, and medical sensors.

Semitec 103AT-2

Almost an industry standard the 103AT-2 is widely used across many industries. We have accelerated deliveries to customers for the production of portable battery backups for use within the NHS.

Asahi Disc Thermostats

Whilst not strictly critical medical devices, our disc thermostats are used within catering equipment, both within the NHS, and new pop up hospitals.
