In an oxygen analyzer for an industrial process, an automotive type oxygen sensor has a sensor element assembly with an outer thin walled shield containing insulation and surrounding the sensor element of the automotive type oxygen sensor.

Method of modifying an automotive type oxygen sensor for use in an

A beam splitter for transmitting and deflecting light comprises a foil having a top surface and at least one hole therethrough. A highly reflective finish is provided on the top surface of the foil. Light is transmitted through the holes in the foil while other light is reflected from the reflective finish on the top surface.

An industrial process oxygen analyzer, and method of using same, incorporates an automotive oxygen sensor to minimize the criticalness of controlling heater temperature during operation. Higher sensor heater temperature, required to accommodate the automotive oxygen sensor, is achieved by application of higher supply voltage to the sensor heater. Current limiting of the heater supply circuit reduces stress on the sensor heater, even at the higher operating temperature.

Automotive oxygen sensor for use in an industrial process analyzer

A pneumatic servo comprises a motor having a shaft for rotation in response to an electrical signal. A cam is connected to the shaft for rotation therewith. The cam has an outer profiled periphery and opposite sides. A pneumatic nozzle having an opening for directing a flow of gas toward one side of the cam near the periphery, obscures the flow by different amounts as the cam rotates to create a back pressure in the nozzle comprising a pneumatic signal. A curved projection engages an opposite side of the cam, the projection being aligned with the nozzle opening and reducing oscillation excursions of the servo at gas pressures in the nozzle of above 12 psi.

Method of performance improvement for an I/P servo

An arrangement for providing radio frequency and electromagnetic interference protection to at least part of circuitry mounted on a circuit board comprises alternating slots and bridges which form a boundary between a protected area of the circuit board and an unprotected area of the circuit board. The circuit portions which require protection are mounted in the protected area and are covered by a top cover having fingers which extend through the slots. Connecting lines between the protected and unprotected portions of the circuit portions extend along the bridges between the slots. A bottom cover engages under the protected area and mates to the top cover for providing electromagnetic interference protection for the circuit portions within the protected area.

Method for RFI/EMI protection of electronic circuitry

Method of applying an automotive type oxygen sensor for use in an

A combustion control system includes a sensor assembly and a process controller, the sensor assembly including sensors for providing output signals indicative of process variables, the process controller responding to the output signals to maintain a desired operation of the process. The process controller continuously monitors parameters of the sensors and provides alarms whenever any of these parameters deviate from setpoint values, the process controller automatically prioritizing these alarms to provide a display of only the most relevant alarms. A housing enclosing the process controller provides EMI/RFI shielding of the process controller including the attenuation and absorption of the EMI/RFI energy.
