<p>The invention provides a method of adjusting the temperature compensation of a temperature-sensitive transducer having a sensor element and a temperature-sensitive element which senses the temperature of the sensor element, and, combined therewith, a signal conditioning circuit which includes the temperature-sensitive element and is capable of effecting such temperature compensation, the method including the steps of making required adjustments to the signal conditioning circuit at one temperature and at another different temperature of the sensor element, characterised in that for making adjustments at the higher of the said one and the said different temperatures the sensor element is heated to that higher temperature by supplying a heating current to a heater element within the transducer and in good thermal connection with the sensor element. If the sensor element and the temperature-sensitive element which senses its temperature are provided on a semiconductor diaphragm of the transducer, the heater element may also be provided on the diaphragm.</p> |
