摘要： An interface circuit for use in a portable apparatus for measuring the electrochemical characteristics of a sample is disclosed. A disposable cartridge (16), including a plurality of interconnected flow chambers, houses a printed circuit board substrate (44) upon which reference and indicating electrodes (40) are formed. The electrodes are employed in the presence of chemical reagents to aid in the electrochemical determination of a sample undergoing analysis. Such a system provides a high source impedance signal. Interface circuitry is provided between the electrodes (40) and measuring electronics which causes a controllable current loop to be formed through the physical contact points (56) between the electrodes and the measuring electronics so that low ohmic contact is established. The control circuitry for the current loop is isolated from the measuring circuitry so that measurements taken are not influenced by the current loop formation.

摘要： An oxygen sensor (24) having an electrolyte member (72) with a thimble that is held in a metal shell (30) by an insulating member (56). The thimble has an external surface (80) and internal surface (82) that are coated with a conductive material. A sleeve (96) is attached to the metal shell (30) by spot welds (108) and a seal is established therbetween. A terminal member (120) located in sleeve (96) includes a first contact ring (142) that is connected by a spring (148) and cylinder (152) to the external surface (80) and a second contact ring (144) that is connected by a coil spring (146) to the internal surface (82). Terminals (164 and 164') carried by terminal member (120) hold a tubular housing (90) of a heater member (92). Tubular housing (90) has an end (94) that is located in the thimble of electrolyte member (72). When electrical current is supplied to heater member (92) the temperature of the thimble is maintained above a minimum operating temperature of the electrolyte member (72). The external surface (80) of member (72) is subjected to exhaust gases while a reference gas is transmitted to internal surface (82). Changes in ion flow are carried by leads (106 and 106') to a controller (20) to provide an indication of the oxygen in the exhaust gases.

摘要： The new probe for measuring the partial pressure P02 in gases is provided with a measurement loop comprising a metal tube on the bottom of which is a pellet composed of a solid electrolyte oxide of which the anions have, at the ambient temperature, a transport member having the unit value. Inside the capsule there is provided a reference gas, outside the capsule is the gas object of the measurement. The electromotive force, resulting from the difference between partial pressures of oxygen, is measured on both sides of the solid electrolyte by means of two electrodes.

摘要： Described is a process for controlling the air/fuel ratio in a spark ignition engine with at least one cylinder, in particular an automobile engine, which enables a catalytic converter (18), with a probe located in the hot exhaust-gas stream (20) containing carbon monoxide, oxides of nitrogen and carbohydrates, to operate at maximum efficiency. The probe measurement signals are converted by an electronic circuit into mixture-regulation and ignition-control signals. The oxygen content of the exhaust-gas stream (20) is measured in the cylinder combustion chamber, downstream of the outlet valve to the cylinder head, or in the individual exhaust pipes, in the protected zone provided by a smooth, aerodynamically shaped deflection device (40), by a resistive ceramic oxigen probe (24) capable of withstanding temperatures up to about 1300 DEG C, with a response time in the millisecond range and without a reference atmosphere. The oxygen probe (24) has a conductivity depending on the partial oxygen pressure. It is arranged as a thin diffusion layer, which constitutes the sensing layer (32), made of a semiconductor titanate on a small ceramic substrate (30).

摘要： The internal resistance of a lambda probe is determined by applying a timed inverse d.c. voltage to the probe via a series resistor, measuring the output voltages with the inverse voltage on and off and calculating the internal resistance from the measured values and known internal resistances. Besides the components of a prior art device, this process requires only a series resistor and a switch. Measurement may be completed within short times without reaching excessively high d.c. loads which could affect the useful life. The measured internal resistance is compared with a reference resistor and the scanning ratio for a fixed-frequency probe heater may be determined with the aid of the deviation thus obtained.

摘要： An oxygen sensor (10) having an electrolyte sensor (40) located in a metal shell (14) and an insulating terminal (102) located in a metal sleeve (72). The metal sleeve (72) is secured to the metal shell (14) to define a reference chamber (68) adjacent the interior of the electrolyte sensor (46). A closed end (74) on the sleeve (72) has a plurality of openings (76, 76'...76n) surrounding a central opening (78). A porous filter (90) has a base (92) that is continually urged against end (74) by the action of spring (118) on terminal (102). A grommet (124) located in the central opening (78) has a cylindrical body with a flange (136) that radially engages filter (90) and a series of lands (132, 132' or 132n) that form a plurality of sealing surfaces on lead (12) that connects the electrolyte sensor (46) with a controller. Changes in temperature which cause the components of sensor (10) to expand and contract at different rates are compensated by the grommet (124) and filter (90) to assure that water does not enter the reference chamber (68) through the openings in the closed end (74).
