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 detectorsignals, 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 thepower 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 behoused in a suitable Ex enclosure when used in Hazardous areas
