How To Use MQ-135 Gas Sensor - Codrey Electronics

2020-07-05· If you want to do anything serious with MQ-135 gas sensor, then you should learn to analyze this plot pretty well. However that needs some skill and patience as the scale is log-log in a linear scale, the behavior of the gas concentration with respect to the resistance ratio is exponential (not linear). For determining Rs/Ro, you can use the fact that the Rs/Ro ratio is a constant in ...

Thermowell - Wikipedia

The temperature sensor such as a thermometer, thermocouple, or resistance temperature detector is inserted in the open end of the thermowell and typically spring-loaded to ensure that the outside tip of the temperature sensor is in metal to metal contact with the inside tip of the thermowell. The use of welded sections for long designs is discouraged due to corrosion and fatigue risks.
