Surface Temperature Sensors

ATC Semitec stock a wide range of temperature sensors which are used across a diverse range of industries from:

Semitec JT Ultra Thin Flexible NTC ThermistorEssential features include speed of response and minimal heat-loss which are critical to obtain accurate temperature control.

Ideally the thermal mass of the surface temperature sensor should be as small as possible, combined with suitable thermal insulation where required.

Our range sensors include:

  • NTC ring surface temperature sensors in plastic, metal and plastic/metal fittings to suit your application.
  • Thin-film JT NTC thermistor sensors offer very fast-acting response for electronics, air-sensing
    and medical applications; similar leaf-style high temperature sensors offer control accuracy up to 250°C in office automation products.
  • Pipe-clip surface temperature sensors can monitor internal fluid temperatures from the outside of the metal pipes on which they are located. Pipe diameters from 12mm to 28mm can be measured with accuracies as close as ±1K and thermal response times of less than 1 second.

    • Operating range -50°C/+125°C
  • ATC Semitec STS1 Pipe Clip Temperature Sensor
    STS1 Clip-on Pipe Temperature Sensors

    The STS1 pipe-clip temperature sensor is IP67 rated and using our FT thin-film thermistor, it offers a very fast thermal response.  Suitable for Legionnaires monitoring and hot water boiler systems.

    • Typical Time Constant (Tc) = ≤1s
    • Temperature Accuracy at 85°C is ±1°C
    • IP67 rated housing
  • Semitec STS3 Thin Flexible Film Temperature Sensor

    This versatile temperature sensor is ideal for air-sensing, particularly for use in fire alarms and heat detectors, component and battery monitoring, rechargeable batteries and medical sensors.

    • Fast response design (Tc ≤ 1s)
    • High accuracy ±1%
    • Operating temperature range: -40°C  to +125°C
  • Semitec STS4 Flexible Surface Sensor for High Temperatures

    High temperature flexible film NTC thermistor sensors for monitoring surface temperatures up to 230°C.  Laser-printers, photocopiers and catering applications all benefit from using these “soft touch” sensors.

    • Fast response design (Tc ≤ 1s)
    • High temperature point calibrations e.g. at 180°C
    • Operating range up to 230°C
