Abstract (en)
[origin: JPH03205725A] PURPOSE: To make switching amplitude larger and preheating period longer, in a temperature switch for a radiant heating means having a sensor tube enclosed by an electrically insulating outside tube by providing the outside tube with a ceramic material absorbing and reflecting the radiation from a radiation source. CONSTITUTION: In a temperature switch for a radiant heating means 11 having a sensor tube 43 enclosed by an electrically insulating outside tube 45, the outside tube 45 has a ceramic material at least substantially absorbing and/or reflecting the radiation from radiation sources 18, 20. On one end of the tube 45 of steatite, a heater and a glass ceramic plate are electrically insulated, and on the other end, reflection, absorption and radiation by a heat medium are shielded. A temporary response delay and a large switching hysteresis are imparted to a sensor 27. Thus, the thermal inertia in the outside tube is increased to increase the response delay, and this increase in thermal inertial is effective to precisely hold a set temperature.
