Patent number: 12140309Abstract: A regulation device for regulating a mixing ratio (x) of a gas mixture comprises a first conduit (1) for carrying a flow of a first gas (e.g., air) and a second conduit (2) for carrying a flow of a second gas (e.g., a fuel gas). The first and second conduits (1, 2) open out into a common conduit (3) in a mixing region (M) to form the gas mixture. A first sensor (S1) is configured to determine at least one thermal parameter of the gas mixture downstream from the mixing region. A control device (10) is configured to receive, from the first sensor, sensor signals indicative of the at least one thermal parameter of the gas mixture and to derive control signals for adjusting device (V1) acting to adjust the mixing ratio, based on the at least one thermal parameter.Type: GrantFiled: October 5, 2018Date of Patent: November 12, 2024Assignee: Sensirion AGInventors: Mark Hornung, Andreas Rüegg, Eric Monnin, David Kiliani, Samuel Wehrli, Daniel Traeutlein

Patent number: 11946888Abstract: A thermal sensor device is configured to determine a fluid parameter of a fluid based on the heat transfer behavior of the fluid. The sensor device comprises one or more heaters and means for determining a response of the sensor device to heater power being supplied to the heaters. For detecting sensor faults, the sensor device is operated in two different modes of operation. First and second values (cstatic, cdynamic) of the same fluid parameter are determined in the two modes. A fault indicator value (F) is derived by comparing the first and second values. The first mode of operation may be a steady-state mode, the first value (cstatic) being based on a steady-state response of the sensor device to heater power being supplied to the heaters, and the second mode of operation may be a dynamic mode, the second value (cstatic) being based on a transient response.Type: GrantFiled: December 2, 2021Date of Patent: April 2, 2024Assignee: Sensirion AGInventors: Eric Monnin, David Kiliani, Andreas Rüegg, Mark Hornung

Publication number: 20230324270Abstract: In a method of determining a flow rate of a flow of a fluid of interest in a fluidic system, a raw flow rate signal (Qsensor) is determined using a flow rate sensor. The raw flow rate signal is corrected using a flow rate correction function (?) to obtain a corrected flow rate signal (Qsensor,corr). The flow rate correction compensates for a flow rate signal error that is caused by integration of the flow rate sensor into the fluidic system. It is based on a reference correction function (?) that is indicative of a flow rate signal error for a flow of a reference fluid due to the integration of the flow rate sensor into the fluidic system.Type: ApplicationFiled: April 7, 2023Publication date: October 12, 2023Inventors: Andreas RÜEGG, Nicolas MOELLER

Publication number: 20230194450Abstract: A thermal sensor device serves for determining a concentration of a target gas in a gas sample that further comprises a disturbance gas. The thermal sensor device comprises first and second measurement structures (1, 2) comprising first and second temperature sensors (TS1, TS2) and a heater element (31) operable to cause heat transfer to the measurement structures through the gas sample. Processing circuitry provides heating power (P3) to the heater element and derives an output signal (S) based on a response of the temperature sensors to the heating power, the output signal being indicative of a concentration of the target gas in the gas sample. The first and second measurement structures have different heat dissipation capabilities, and the processing circuitry derives the output signal from a weighted difference of temperature signals from the first and second temperature sensors.Type: ApplicationFiled: December 15, 2022Publication date: June 22, 2023Applicant: Sensirion AGInventors: Andreas RÜEGG, David KILIANI, Matthias STUDER, Nicolas MOELLER, Mark HORNUNG, Lukas BÜRGI

Patent number: 11674833Abstract: A thermal sensor comprises an active element (41), e.g., a heater or cooler, at least one temperature sensor (31), and processing circuitry (50). The processing circuitry causes a change of power supplied to the active element (41). It then determines, at a plurality of times, a thermal parameter based on an output signal of the temperature sensors and analyzes the transient behavior of the thermal parameter. Based on this analysis, the processing circuitry determines a contamination signal that is indicative of a contamination on a sensing surface of the thermal sensor. If the thermal sensor comprises a plurality of temperature sensors arranged in different sectors of the sensing surface, a multi-sector thermal signal can be derived from the outputs of the sensors, and determination of the contamination signal can be based on the multi-sector thermal signal.Type: GrantFiled: December 10, 2019Date of Patent: June 13, 2023Assignee: Sensirion AGInventors: Mark Hornung, Andreas Rüegg, Harry Figi, Lucas Huber
