Chapter 2 Electrochemical Sensors

these sensors, in terms of sensitivity, selectivity, response time, and operating life. For example, a low concentration gas sensor with very high sensitivity uses a coarseporosity hydrophobic membrane and less restricted capillary to allow more gas molecules to pass through to produce enough signal for better sensitivity. However, this design also al lows more of the electrolyte’s water ...

Cross references Gas Tables Gas Detection /

Electrochemical sensors are manufactured as specific sensors for one gas, for all that there exist some cross sensitivities to other gases. Generally these cross references are not a problem in gas detection in the area of safety, but they can be a complication in the process detection they can cause false alarms. This page includes links to cross reference data of the electrochemical sensors.

Gas sensor cross sensitivity Blackline Safety

When sensors get cross sensitive readings, we recommend you allow the device to sit and stabilize. Depending on the gas it was exposed to, it can take as little as a few minutes or as long as several hours. Once the readings have stabilized, you can recalibrate the device if desired. What gas combinations produce noticeable cross sensitivity? Almost all gases cause some cross sensitivity, but ...

· But no reports are available which show SAW based CO 2 gas sensor operating at a hightemperature (>350 °C) and address the crosssensitivity towards other toxic gases. In the present work, CO 2 sensing characteristics and its crosssensitive behavior for CO and H 2 gas have been studied using calcium doped zinc oxide (Ca_ZnO) thin film coated langasite based SAW sensor.

Even with a brand new filter, a sensor is still susceptible to false readings from these other gases. The response of the sensor to the chemical reaction from these gases other than the target gas is called its crosssensitivity. Figure 2 shows the crosssensitivity of one carbon monoxide sensor to other gases both with and without a filter and after the sensor has been allowed to age.
