Flat Surfaced Alcohol Sensor
MP-3 model with advanced planar construction is comprised of heater and metal oxide semiconductor material of subminiature Al2O3 ceramic plate, fetch out electrode down-lead, encapsulation in metal base and cap. When the target gas(Alcohol) exist , The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
Features:
Full solid state semiconductor alcohol sensor
Lower voltage and consumption
Small size
Fast response and resume
Highest sensitivity
Excellent stability and long life
Easy circuit and big signal output
Excellent selectivity
Application
It is used for detecting whether the driver and other people who drink alcohol, or detecting whether ethanol steamy exist in other places.Symbol | Parameter name | Technical condition | Remarks |
