1. What are the specific applications of oxygen probes?
o Most common:Industrial Furnace Atmosphere Control(like metal heat treatment, carburizing, annealing, sintering)Burn Control Optimization(boilers, kilns)Engine exhaust analysis, environmental monitoring(Emission Monitoring)Laboratory Gas Analysis？
2. What type of oxygen probe is required?This is usually determined by the application.
o Zirconia Oxygen SensorThis is the most commonly used type in industry, utilizing the principle of zirconia solid electrolyte, suitable for high temperatures (usually > 400°C) and industrial process monitoring. There are also many subtypes.
Heater equipped: Operates at lower temperatures.
Direct Insertion/Threaded Mounting/Facing Type: Different mounting methods.
Does the probe body include a transmitter: split or integrated signal output?
o Electrochemical Oxygen SensorPriced lower with a relatively shorter lifespan (usually 1-3 years), these are commonly used in environments such as environmental monitoring, portable instruments, medical, laboratory, and safety alarms at normal or cooler temperatures. Applications such as paramagnetic oxygen sensors and laser spectrometers (e.g., TDLAS) are suited for more specialized scenarios.
