Prime1 High Resolution Infrared Methane Ch4 Sensor - China

Prime1 Infrared Methane Sensor CH4 Sensor Description and Operation

The Prime1 sensor uses the non-dispersive infrared method to detect the presence of hydrocarbon gases.

The sensor contains an infrared radiation source, a dual element custom infrared detector, a unique optical waveguide into which gas diffuses and internal ARM7 core microprocessor based electronics to provide a voltage output which is independent of the power supply polarity.

The sensors can be configured to provide a pellistor format output, typically mid supply at zero with the voltage output increasing with respect to the detector pin by 100mV at range, or a linear voltage output, typically 0.4V - 2.0V over range with respect to the negative supply pin.

In addition, the output can be read and the internal configuration can be accessed by a serial communications link.

The communication link contacts are pads in the 3 pin version Prime1 and pins in the 5 pin version Prime1 - The internal electronics perform all the functions of driving the optical parts of the sensor, extracting the detector signals, converting the signals to a concentration, applying temperature compensation and scaling the output.

When in a pellistor configuration, the Prime1 can replace catalytic sensors in existing circuitry subject to the power supply requirements.

External components will be required to meet the power supply requirement when a Prime1 is used in constant current pellistor circuitry.

The Prime1 is not currently Ex approved so should be housed in a suitable Ex enclosure when used in Hazardous areas.
