Problems solved by technology

Therefore, miniaturization of radiation thermometers is increasingly difficult
[0012] In addition, since the output signal of the thermopile is very small, the output signal of the thermopile has to be amplified with a high amplification factor
In this way, when the output signal of the thermopile is affected by noise, the measurement accuracy is significantly reduced

Abstract

The invention discloses a radiation thermometer. The thermopile is basically arranged in the center of the head of the radiation thermometer. A preamplifier substrate is disposed close to the thermopile. A heat spreading member made of a high thermal conductivity material is disposed around the thermopile and preamplifier substrate. The main substrate and the laser diode are disposed between the upper surface of the head case and the upper surface of the thermal diffusion member. The power supply substrate and the laser diode are disposed between the lower surface of the head case and the lower surface of the thermal diffusion member. The thermopile, the preamplifier substrate, the main substrate, the power substrate and the laser diode are all arranged not to be in contact with the thermal diffusion member.

Description

technical field [0001] The present invention relates to a radiation thermometer that measures the temperature of an object to be measured by detecting infrared energy radiated from the object. Background technique [0002] Heretofore, there has been a radiation thermometer (for example, refer to Japanese Patent Laid-Open Publication No. 7-324981) that detects infrared energy radiated from an object to be measured and corrects the measured infrared energy with the emissivity of the object. The above-mentioned infrared energy can be used to measure the actual temperature of the object to be measured. [0003] Generally, a radiation thermometer detects infrared energy through a heat sensitive element such as a thermopile or the like. The thermopile includes an infrared receiving portion (hot junction) having a plurality of thermocouples connected in series. In this thermopile, when infrared rays are incident on the infrared receiving portion, a temperature difference is gener...
