  3. About electrochemical gas sensor

We will answer many questions about electrochemical gas sensors.

Q.1What happens if I am exposed to a high concentration of gas that exceeds the limit concentration?

A.The zero point may become unstable depending on the concentration.

Q.2What happens if a voltage different from the specifications is applied?

A.It will put a load on the sensor and cause damage.

Q.3Is it possible to use it in an oxygen-free atmosphere?

A.Oxygen is required due to the detection principle, so it cannot be used.

Q.4Is there a specification for the storage environment after purchase?

A.The recommended storage temperature is 0 ° C to 20 ° C.Please contact us if it is difficult to store within this range.

Q.5How long does it take from turning on the sensor to detecting gas?

A.Depending on the detection concentration, gas can be detected in about XNUMX hour.

Q.6Is it possible to solder?

A.It is possible if it is a consumer sensor.For industrial products, use a dedicated socket.

Q.7Is it possible to detect gas even with a single power supply circuit?

A.Both power circuits are recommended, but gas can be detected.There is a recommended circuit for a single power supply circuit, so please contact us for details.

Q.8What is the recommended calibration frequency for the sensor?

A.There is no need to calibrate the sensor itself.Match the calibration frequency of the device equipped with the sensor.

Q.9Is there any fluctuation in the sensor output due to the flow rate?

A.It will change slightly.

Q.10How much sensitivity is there other than the target gas?

A.It depends on each sensor.Please refer to the catalog for details.

Q.11Please tell me the lower limit of detection concentration.

A.It depends on each sensor.The recommended sensor varies depending on the application, so please contact us for details.

Q.12How long does the sensor last?

A.It takes 7 years for consumer sensors and 1 to 3 years for industrial sensors.Please refer to the catalog for details.

Q.13What happens if the operating temperature range is exceeded?

A.High temperatures significantly reduce the life of the sensor.If the temperature exceeds 80 ° C, the resin used for the sensor will be deformed and cause damage.On the contrary, if the temperature becomes low, the electrolyte may freeze.

Q.14How should I dispose of the sensor?

A.Please dispose of it as industrial waste according to each municipality.

Q.15Please tell me the detection principle

A.Please refer to here.
