Cortex Metamax 3B™ uses a breath-by-breath technique. During ergospirometry, the candidate wears a breathing mask strapped to his face, breathing through a turbine-equipped volume sensor with a range of 0.05 to 20 l/sec, a sensitivity of 7 ml, and a precision of 2 percent. The oxygen analyser contains an electrochemical cell, allowing a measurement range from 0 to 35 percent. The infrared carbon dioxide sensor measures values from 0 to 13 percent (accuracy 0.1 Vol. percent). Both sensors have a measurement kinetic of 100 ms.
Laboratory Gas Pipeline Construction

The carbon dioxide sensor should incorporate a two-beam infrared sensor for the continuous monitoring of the ambient air to detect carbon dioxide concentrations. It should utilize infrared measuring with integrated temperature and drift compensation and have are calibration interval of 3 years. The sensor should have a standard analog output (0) 4–20 mA or (0) 2–10 V DC and an RS–485 interfaces.

To conduct the experiment of FC automatic wind control with unbalanced gas gushing in the stope, at the inlet side of the stope, a CO2 gas storage cylinder, pressure relief valve and mass flow controller were used to release the experimental gas into the pipe network quantitatively and discharge it from the return airline. As the gas is a flammable and explosive gas, for the safety reasons, we choose carbon dioxide instead of gas. The most important factor affecting the final rule is the difference of density. And we measured the concentration of carbon dioxide with a long distance after the release point, and in the high speed airflow in the pipe, and mix well with the airflow. A CX mass flow controller was used to quantitatively release CO2, and a GRG5H carbon dioxide sensor was used to monitor the concentration. A schematic diagram of the gas monitoring system on the experimental platform is shown in Figure 5.

To carry out plant inspection task, a sensor unit consists of a visible light camera, a thermal camera, a carbon dioxide sensor and a microphone is used, as Figure 8(a) shows. The sensor unit is fitted on a 3 DOF manipulator (hereinafter: ‘sensor unit arm’) and the joint configuration is arranged as yaw, pitch, pitch, as shown in Figure 8(b). The sensor unit arm is fitted on the third joint of the folding arm. With this configuration, the sensor unit arm shares the movement with C-hand when first, second and third joint of the folding arm rotates. The sensor unit arm can be controlled differently based on the control mode.

RR measurements are typically taken via manual counting in non-emergency settings. This is regarded as the ‘industry standard’ while the gold standard is via capnography. This method involves recording the concentration of carbon dioxide in respiratory gases through attaching a capnograph (carbon dioxide sensor) to a plastic cannula worn over the nose and mouth [34]. Understandably, these measurement techniques are not suitable for ubiquitous monitoring of RR.
