Product Description:

YJJ NAP-50A N50A Catalytic Combustion Gas Sensor Can Detect A Variety Of Gases

Features:

A small volume low-power gas sensor NAP-50A

NAP-50A is a small size and low power sensor.NAP-50A is mainly used for gas detection.Compared with NAP-55A, NAP-50A has less disturbance to alcohol alarm, and the gas detector made by NAP-50A is more reliable.Below are the basic parameters, but it is for civilian use. See the user manual for more information.Refer to the sensor test circuit of NAP-66A.

Parameter Categories Content Details
Detection Target Can detect methane, ethane, isobutane, hydrogen and other combustible gases
Detection Range Methane: 0.05 - 5%, Ethane: 0.05 - 3.2%, Isobutane: 0.03 - 1.8%, Hydrogen: 0.05 - 4%; Hydrocarbon gases: 1 - 100% LEL (common detection range is 1 - 50% LEL)
Power Supply Parameters Rated voltage: DC 2.5 ± 0.25V, AC 2.5 ± 0.25V (effective value, frequency 50 - 60Hz); When applying 2.0V voltage, both DC and AC currents are 150 - 170mA
Output Characteristics Air output voltage: - 35~+35mV; 3000ppm methane corresponds to output 10 - 16mV, 1400ppm isobutane corresponds to output 9 - 14mV, 1400ppm hydrogen corresponds to output 7 - 12mV, 1% ethanol environment corresponds to output lower than 10mV
Environmental Parameters Working temperature: - 10~+50℃, working humidity: ≤ 95% RH; Storage temperature: - 10~+50℃, storage humidity: ≤ 99% RH (no condensation)
Other Characteristics Long service life of up to 10 years, with good stability, recovery and reproducibility, fast response speed, and good linear output signal for urban gas concentration detection
Main Applications
Household gas leakage alarm device: This is one of its core application scenarios, which can be integrated into household natural gas or liquefied petroleum gas leakage alarm devices. Once the gas leakage concentration reaches the dangerous threshold, the sensor can quickly capture the signal and trigger an alarm to avoid explosion, poisoning and other safety accidents.
Combustible Gas Concentration Meter: With the advantage of linear output signal, it can be used to make civilian or small commercial combustible gas concentration meters, which can display the concentration values of methane, hydrogen and other gases in real time, making it convenient for people to intuitively grasp the gas concentration situation.
Small Gas Detector: Due to its ultra-small size and low power consumption, it is suitable for the core detection components of portable combustible gas detectors, meeting the rapid detection needs of combustible gas in mobile scenarios such as outdoor operations and on-site maintenance.
In addition, compared with the NAP - 55A sensor of the same series, its low alcohol sensitivity feature enables it to effectively reduce false alarms when used in scenarios where alcohol vapor may appear in kitchens, further improving the reliability of the equipment.
