Miniature Medical Temperature Sensors

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

Thermistors, from our innovative suppliers, are already used in brand leading thermometers, catheters and wearable technology, and many emerging healthcare products.

One of our latest innovations is the F-micro miniature thermistor sensor which was developed for use in medical applications e.g. catheters. Utilising smaller and smaller FT thermistors, the F-micro can now be supplied in tubes as small as 0.28mm with a time constant as fast as 20ms. With 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 increasing being used within medical devices, due to its exceptionally fast response times and flexible film technology.

For non-contact applications, the NC temperature sensor utilises the latest FT thermistor technology to sense infrared energy with a high signal strength. In infrared sensing applications where a very fast response to temperature change is required, we manufacture thermopile sensors which have a thermal response of around 15 milliseconds.

Call us today on 01606 871680 to discuss your application’s thermal sensor requirements.  Using our extensive technical knowledge and innovative supplier base, we will work with you to provide the optimum solution for your product.

  • Semitec F-Micro Miniature Temperature Sensors
    Semitec F-micro Miniature Temperature Sensors

    Using further advances in Semitec’s thin-film thermistor technology, the Fμ temperature sensor has been specifically designed with medical purposes in mind. They feature extremely fast response time (<51ms), and high accuracy (±0.14K at 37°C).

    We have 2 stock items available and now in packages as small as 0.3mm (D) x 1.8mm (L) with a Tc≤20ms.

    The Fμ temperature sensor can be used in catheters, body temperature monitoring devices or where an extremely small sensor needs to be incorporated with other clinical instruments.

     

     

     

  • Flexible, thin film, NTC thermistors
    Semitec JT Ultra-Thin Flexible Film NTC Thermistor

    Semitec’s JT series of thermistors are ultra-thin flexible film NTCs that give a very fast response to temperature change. Laminated within 2 polymer layers it is one of thinnest available worldwide at less than 0.5mm thick.

    Whilst increasingly used within medical device applications, it is a versatile thermistor which is used within battery packs, e-vehicles, mobile devices and surface/air  temperature sensors.

     

  • Epoxy coated NTC thermistor
    Semitec ET-3H Small Bead Epoxy NTCs

    The ET-3H thermistor was originally developed for clinical thermometer applications.
    With bead sizes of 1.4mm (or less),and flexible wire. Its fast response and high accuracy make it a universal choice for low-cost, clinical thermometers.
    R37 tolerances of ±1% or smaller and matched resistance groups help to minimise unit cost whilst maximising sensor accuracy.

  • ATC Semitec SP Interchangeable Thermistors
    ATC Semitec SP Interchangeable NTC Thermistors

    SP series NTC thermistors offer accuracy as small as ±0.1°C for clinical sensor applications. These interchangeable or R-T curve-matched thermistors guarantee a very high accuracy over a wide temperature range, e.g. 0~70°C and are also available in micro miniature packages such as our ATC Semitec SPMM series.

    R25 values vary from 1kohms to 100kohms and can be used from -50°C to +150°C.

  • ATC Semitec SPMM Interchangeable Miniature Thermistor
    ATC Semitec SPMM Miniature Interchangeable NTC Thermistor

    The SPMM series is a range of extremely small temperature sensors in which we can offer NTC thermistors with precision interchangeability. The sensing portion (as small as 0.60mm dia. x 6mm long) allows it to be easily incorporated with other sensors in medical instruments and other multi-sensing applications. Utilising our series of miniature interchangeable NTC’s, a wide range of resistance values, RT curves and accuracies can be offered.

  • Thermopile Non Contact Sensor
    Thermopiles - Non-Contact Infrared Sensors

    Our Semitec 10TP series thermopile is a very fast-acting infrared sensing device suitable for non-contact applications such as clinical ear-drum thermometers.
    The  Semitec 10TP583T thermopile is the result of silicon micro-machining technology where a series of miniature thermocouple junctions are combined to provide an output EMF based on the received infrared energy.

    • Operating temperature range is from -10°C to 100°C
