Quick Response Sensors

The thermocouples used in our standard material temperature sensors tend to present a problem associated with the large gap between the indicated temperature and the actual temperature of the material. This gap can rise from the following factors:

  • The sensor’s response time is too slow to catch up with the actual temperature.
  • The sensor is equipped at the bottom of the chamber and may be affected by cooling water circulating in the jacket.

We have developed a new temperature sensor of a faster response time which is less affected by the temperature of the fitting structure (Figure 1).

temperature sensors
  • The thermocouple is smaller in diameter and has a faster response time than the conventional type (Figure 2).
  • The sensor is insulated with a plastic collar to insulate from heat conductivity, which minimizes the difference between readout temperature and actual temperature (Table 1).
  • The sensor is fitted by means of a holder to ensure interchangeability with the conventional sensors.
