Fast Response Temp Probes

Some temperature control applications, such as domestic showers and instant water heaters, require a very fast thermal response of 1 second or less. This is to maximise the thermal efficiency of the device and avoid potential scalding of the user.

In response to this, ATC Semitec stock a number of very fast-response temperature probes where the NTC thermistor is situated in the very tip of the sensor. This reduces the thermal path to the thermistor and thus minimises the thermal response time. Response times can be further accelerated by using our thin wall tip or exposed NTC sensor.

Our standard sensor packages include: screw threaded bosses, bayonet fittings and push-fit/clip-in designs – all of which are available with flying leads and/or industry standard connector options.

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.

  • FRP1 Fast Response Temperature Probes

    The FRP1 sensor has a 2.1mm dia tip in a 316 stainless housing with a brass mounting collar.  This fast response NTC thermistor probe is ideal for hot water temperature applications.

    • Fast response design (Tc ≤ 1s)
    • Accuracy possible to ±0.2K (over 0-70°C)
    • Temperature operating range between -50°C to +150°C
  • Semitec-FRP2-Exposed-NTC-Sensors
    FRP2 Exposed Tip Temperature Sensors

    The FRP2 sensor design uses an exposed glass bead NTC thermistor to maximise its thermal response.  The exposed sensor measures air temperature change within seconds and is suitable for use up to 250°C.

    • Fast response design (Tc ≤ 1s)
    • Accuracy ±3% or better
    • Operating temperature range: -50°C to +250°C
  • FRP3 Screw-in Immersion Temperature Sensors

    The FRP3 temperature sensor is fitted with an industry standard 1/8″BSPG thread and integral connector.  Commonly used in gas boilers, they are perfect low-cost sensors for numerous applications.

    • Accuracy ±1%, available ±0.2K (0-70°C)
    • Operating temperature range: -40°C to +125°C
    • Available in brass or nickel-plated
  • FRP4 Fast Response Threaded Stud Temperature Sensor
    FRP4 Stud Mount Temperature Sensor

    Fast response M5 stud sensor in brass or PPS with the NTC thermistor housed within the screw thread portion to optimise the thermal response.  Different thread sizes and body materials available.

    • Fast response design (Tc ≤ 3s)
    • Accuracy ±3% (or better)
    • Operating temperature range: -50°C to +180°C
  • FRP5 Thinwall Tip Temperature Sensor

    The FRP5 sensor design offers a 2.1mm diameter x 7.6mm long thin-wall sensing tip in 316 stainless steel.  This maximises the NTC position inserted in the fluid for the fastest possible speed of response.

    • Very fast thermal response (Tc ≤ 1s)
    • R25 accuracy ±3%, ±1% also possible
    • Operating range up to -50°C/+200°C
