Abstract: A thermal sensor array device (100) comprises a substrate having a cavity (291) formed therein. An infrared absorbing membrane (200) is suspended over the cavity from a first and second beams (202, 206), the first beam (202) being thermally coupled at one end thereof to the substrate (Cj1) at a first cold junction and the second beam (206) being thermally coupled at one end thereof to a second substrate cold junction (Cj2). Thermocouples are disposed over the first and second beams (202, 206) and on the membrane (200). The thermocouples are arranged on the first and second beams (202, 206) and the membrane (200) as first and second thermopiles (300, 320). The first and second thermopiles (300, 320) are arranged on the membrane (200) to measure a sum of first temperature differentials between the first substrate cold junction (Cj1) and a hot junction (Hj) on the membrane (200), and second temperature differentials between the second substrate cold junction (Cj2) and the hot junction (Hj) on the membrane. The first thermopile (300) is configured to connect selectively to the second thermopile (320) in series and anti-series.

Abstract: A circuit for determining and/or compensating for a measurement error of a sheathed sensor due to a property of a sheath of that sheathed sensor comprises a first and a second terminal for connecting to a pair of sensor signal leads of a sensor element in a sheathed sensor and a voltage measurement circuit. A switching unit controls switching an electrical connection between a first and a second state. A correction measurement circuit generates a correction signal indicative of that a measured current running from the first terminal through the switching unit. A controller receives the measurement and correction signal in both the first and second state, and calculates an error value indicative of the measurement error and/or a sensor readout value that is corrected for the measurement error by taking the measurement and correction signal into account as obtained in both the first and second state.

Abstract: A method of measuring temperature based upon a system of equations applying Stefan-Boltzmann's law and using a measurement value for an object to be measured and an ambient temperature value (Ta) comprises: pre-calculating (200, 202) a first vector (LUT1) and a second vector (LUT2). The first vector (LUT1) is a series of values proportional to received power based upon respective temperature values and in respect of a predetermined generic range of temperatures. The second vector (LUT2) is a series of sensitivity characteristic factor values based upon expected measured temperature values and in respect of a predetermined range of expected object measured temperatures. The first vector (LUT1) and the second vector (LUT2) are used (206) to generate a temporary vector (LUTT) of a series of values limited to the ambient temperature value to solve the system of equations in respect of the measurement value for the object, thereby determining (208) a temperature (To) for the object from the measurement value.
