あり得る。(Prior art) A fire sensor is attached to the exhaust duct or related equipment, and when this fire sensor detects a temperature higher than a set value, it issues an alarm and takes measures such as turning off the power source of the high temperature source. It is common to do this. For this reason, fire sensors are installed in various places inside buildings, but since abnormally high temperatures such as fires do not normally occur for a long time, in an emergency, fire sensors (and those connected to them) are installed. alarm circuit) may not operate.

定まではできない問題があつた。 Therefore, the fire sensor must be tested regularly to confirm that it is working properly and to be prepared in the event of an abnormality. By the way, fire sensors are generally installed in high places, and those installed in exhaust ducts or related equipment as mentioned above are often installed in narrow spaces sandwiched between equipment. Since the number of particles is not small, there was a problem that testing work was difficult or impossible with the relatively large testing equipment used in the past. Furthermore, although testing was possible, there was a problem in that it was not possible to measure the operating temperature of the fire sensor.

いる。 A sensor test chamber 13 is formed between the flame prevention plate 3 and the tip (left end) of the cylindrical body 1, and the tip is formed in an insertion opening for a fire sensor 14 to be tested.
A large number of slits 15 are provided in this portion of the cylindrical body 1 to allow air circulation. And the flame prevention plate 3 inside the sensor test chamber 13
A temperature sensor 17 attached to the grip 16 is attached near the handle. The grip 16 is used together with the grip 12 of the burner 8 to hold the entire device. A thermocouple is used here as the temperature sensor 17, and the temperature sensor 17 is connected to a thermocouple thermometer 19 via a cord 18.

サ１７は平均的な温度を検出することができる。 This test device configured as described above is used as follows. First, open the flame adjustment pot 10, ignite the burner 8, and while measuring the temperature of the temperature sensor 17 with the thermocouple thermometer 19, adjust the flame amount so that the temperature reaches the working setting temperature of the fire sensor 14 under test. . At this time, the flame prevention plate 3 prevents the flame from directly hitting the temperature sensor 17, so the temperature sensor 17 can detect the average temperature.

する。 When the temperature in the sensor test chamber 13 becomes constant at the set temperature of the fire sensor 14 to be tested, the cylindrical body 1
is moved to the vicinity of the fire sensor under test 14, and the fire sensor under test 14 is inserted into the tip thereof. This confirms the operation of the fire sensor 14 under test. Then, read the temperature when activated with a thermocouple thermometer.
In this case, the slit 15 functions to prevent hot air from being trapped in the sensor test chamber 13 and the temperature from rising when the fire sensor 14 under test is inserted.

In this case, it can be seen that the pore area ratio is optimal when it is 20% or more. Figure 4 shows combustion chamber 4
The relationship between the porosity and the temperature inside the sensor test chamber 13 is
Again, it is expressed using a set temperature of 100°C. From this figure, it can be seen that if the open area ratio is less than 10%, the burner 8 will be extinguished, and that 25% or more is optimal.

The test can also be performed easily and easily. Further, by providing a large number of air holes on the outer periphery of the cylindrical body from the base end to the middle part, the burner inside the combustion chamber burns in the same way as usual. Further, by providing a large number of slits on the outer periphery of the tip of the cylindrical body, it is possible to prevent hot air from being trapped around the temperature sensor and causing a rise in temperature. With these features, it is now possible to accurately measure the operating temperature, which has been impossible to measure up to now.
