Package smoke sensor or smoke thermostat is a type of safety switch related to smoke exit from the package chimney. This sensor package, which is a type of NC sensor, is also called chimney safety thermostat. The package smoke thermostat is actually a heat-sensitive switch that is normally closed. This sensor is activated if the temperature adjustment cap reaches a temperature between 66 and 84 degrees Celsius. First, it warns the package board to turn off the package. Finally, the chimney error is displayed.
Introducing Package Smoke Small Sensor Package
The package smoke sensor is a type of NC thermal switch that is installed on the adjustment cap of fanless packages. The adjustment cap heats up when the smoke is not released from the package chimney for any reason. Blockage of the chimney leads to the heating of this cap and the heat will be transferred to the thermal switch.
If the temperature of the package smoke thermostat exceeds the maximum desired temperature (75 degrees Celsius), a warning message will be issued to turn off the package. will be. The package burner will be lit again only if the smoke thermostat detects a safe condition. If the smoke flow path from the chimney is closed and toxic gases return to the package, this sensor is activated. In these cases, this smoke sensor issues the order to turn off the package.
Where is the Isatis package smoke sensor?
As we said above, the smoke sensor in the package is a type of NC thermal switch that is activated at a temperature between 60 and 80 degrees Celsius. The smoke sensor is installed on the middle blade of the adjustment cap of the package without a fan and in the smoke outlet.
Package Smoke Sensor Test
To test the package smoke sensor, the multimeter should be in the short circuit test mode. Then the multimeter wires should be connected to both ends of the thermostat terminals. If you hear a beep, the package smoke sensor is healthy and functioning properly. To test the package smoke thermostat, use an voltmeter or multimeter in beezer mode. Connect the wires of the voltmeter to the thermostat connections and wait for the beep sound. If the key is in the NC position and the temperature is low, the buzzer will sound. But if the key is in the NO position, you will not hear a sound from the buzzer. Now connect the wires and shake the plug heads slowly. If the sound of the horn goes off and on, the key is damaged and must be replaced or repaired.
Symptoms of Package Smoke Sensor
Continuous turning on and off of the package is one of the signs of smoke sensor failure. The non-emission of dangerous gases from the chimney and the activation of the temperature sensor lead to the shutdown of the package. But the failure of the sensor causes other problems in this situation.
As we said, sometimes toxic gases are returned inside the package due to the blockage of the chimney pipe of the package. Now, if the smoke sensor is broken, the package will be turned off at a lower temperature after the sensor's warning.
Usually, in these cases, the package will turn on and off continuously. Therefore, installing a smoke sensor helps to prevent the package temperature from rising above the standard. After other sensors, the package smoke thermostat is the last point that turns off the package to prevent the temperature from rising.
