    摘要: A gas exhaust by-product measurement system is provided. A gas chamber is configured to receive exhaust from the exhaust output. A light source, light detector, and at least one optical element are positioned so that a light beam from the light source is directed to the at least one optical element a plurality of times before reaching the light detector. At least one heater provides heat to the at least one optical element. A plurality of purge gas nozzles are in fluid connection with the optical cavity. A high flow line is in fluid connection between a purge gas source and the plurality of purge gas nozzles. A low flow line is in fluid connection between the purge gas source and the plurality of purge gas nozzles. At least one flow controller manages a plurality of flow rates including a high flow and a low flow.

    摘要: A method for monitoring an oil level in a machine includes transmitting a light beam into an optical system to be reflected or refracted to a receiver to generate a reception signal. The light beam is emitted at a set transmission power, and an oil deficiency is recognized when the reception signal exceeds a predefined level value. The transmission power of the light beam is settable between a minimum and a maximum transmission power, and contamination of the optical system is analyzed by: (a) the transmitter transmits a first light beam at the maximum transmission power to generate a first reception signal, and (b) analyzing the difference between the first reception signal and a second reception signal generated by a light beam at less than the maximum transmission power, the magnitude of the difference representing a measure of the degree of contamination of the optical system.

    摘要: Embodiments of the invention relate to a gas analyzer or other device and to a gas analyzer that is configured with a purger that is configured to remove certain gasses from an interior of the gas analyzer. A molecular sieve is an example of a purger or of a purging structure that may be disposed within the housing of the gas analyzer. The purger may be positioned within or inside of the housing such that the unwanted gasses are absorbed or adsorbed through diffusion. The purger is replaceable.
