Matsuo Precision Thermostats

These sensors are designed for temperature control and monitoring of liquid/coolants where a very fast thermal response is essential. This, combined with a high thermal accuracy, ensures accurate temperature control of the liquid/ coolants to help maximise efficiency.

ATC Semitec stock a number of immersion, inline and clip-on temperature sensors where the NTC thermistor is situated in the very tip of the sensor. This design reduces the thermal path to the thermistor and minimises the response time, allowing for faster temperature control. Screw threaded boss designs, surface sensor fixings for pipes and simple push-fit/clip-in versions are all available with industry standard connector options or flying leads if preferred.

As we age and demands on our personal health increase from day-to-day, the need for new medical device solutions increases accordingly too.  Our range of NTC Thermistor sensors helps to meets those needs and also those of future medical device designs.

Semitec ET series Thermistors are small, fast-responding bead NTCs and have long been associated with clinical thermometer applications.

More recently, the Semitec F micro miniature sensor is fast becoming an industry standard used in ablation and various other catheter types.  The F micro sensor uses our unique thin-film FT thermistor as its sensing element and smaller and smaller iterations of the FT now means that a 0.28mm diameter temperature sensor is possible – the thermal time constant for this size of sensor is as fast as 20 milliseconds!

The FT Thermistor is an 0402 (or smaller 0201) size thin-film NTC sensor on a 150micron ceramic substrate that helps to produce an exceptionally fast thermal response.  As well as being used in various fast-response temperature sensors, it is also now used as the main temperature sensing element in diabetic patch monitors.  Future FT designs will be even smaller allowing for other minimally invasive applications as well as potentially internal organ monitoring.

Our range of high precision NTC thermistors enable engineers to accurately control operating temperatures which is critical in many product applications within the automotive, home automation and medical device industries.

Precision thermistors are highly accurate with 0.5% resistance tolerances (or better) offering long term stability and control; their RT curve interchangeability eliminates the need for individual circuit calibration.  Available with ±0.2°C (0-70°C) accuracy or better, they can operate up to 150°C and so are also suitable for use in automotive applications.
