摘要： An exhaust gas sensor includes a housing and a sensor element supported by the housing. The sensor element includes a support member having an exhaust side, a reference side, and an aperture extending through the support member between the exhaust side and the reference side. The sensor element further includes an exhaust-side electrode on the exhaust side of the support member. The exhaust-side electrode is electrically connected to a contact on the reference side of the support member via a lead extending through the aperture. The aperture is sealed around the lead such that gas cannot pass through the aperture. The support member is oriented substantially parallel to the flow of exhaust gases when the exhaust gas sensor is installed on a vehicle. The sensor further includes a contact pin in the housing that engages the contact and biases the sensor element against a portion of the housing.

摘要： An oxygen concentration detecting apparatus precisely and easily performs diagnosis of a limit current type oxygen sensor. The limit current type oxygen sensor has an oxygen concentration detecting element for outputting limit current proportional to the oxygen concentration and a heater for heating the detecting element. A CPU of a microcomputer controls energization of the heater to activate the oxygen sensor. The CPU calculates element resistance based on the voltage applied to the oxygen sensor and the current detected in the sensor. In a sensor diagnosis routine, the CPU determines whether preconditions for the diagnosis have been met. If all the preconditions have been met, the CPU executes the diagnosis. That is, the CPU determines whether the element resistance is within a predetermined range. If it is below the range, the CPU determines that the sensor has high element temperature abnormality. If the element resistance is above the range, the CPU determines that the sensor has low element temperature abnormality.

摘要： A sensor for sensing in a gas stream a vapor of a liquid. The sensor includes a micropore and a wet temperature sensor. The micropore has an evaporation end and has a lumen to conduct liquid from a supply of the liquid for evaporation at the evaporation end. The wet temperature sensor has a heat sensitive part in contact with the liquid in the micropore. The heat sensitive part circumscribes the micropore and forms part of the lumen. Heat loss due to evaporation of the liquid when the wet temperature sensor wet with the liquid is placed in the gas stream will result in the temperature sensed by the wet temperature sensor being lower than the non-evaporative temperature of the gas stream. This lowering in temperature can be measured to determine the concentration of the vapor in the gas stream. An example of such a sensor has a thermocouple junction having micropores passing through the thermocouple junction.

摘要： The apparatus includes a mixing chamber for mixing gas from a gas supply to be tested with air to form a gas-air mixture. The mixing chamber includes a gas inlet port through which the gas is received, an air intake port through which the air is received, and an outlet port through which the gas-air mixture leaves the mixing chamber. The apparatus includes a flow control valve that can be connected to the gas supply to enable a user to selectively adjust the flow rate of the gas from the gas supply to the apparatus. The apparatus also includes a mass flow sensor positioned between the flow control valve and the gas inlet port of the mixing chamber for measuring the mass flow rate of the gas flowing into the mixing chamber. A motorized fan is positioned in a conduit connected to outlet port of the mixing chamber for drawing the gas-air mixture out of the mixing chamber to a location where it can be sniffed by the user to detect odor. The apparatus also includes a tachometer for measuring the rotational speed of the motorized fan and a microprocessor controller responsive to signals from the tachometer for controlling the rotational speed of the motorized fan such that it is maintained at a substantially constant speed. The apparatus can be linked to a personal computer to enable data to be exchanged between the personal computer and the apparatus.
