Transducer temperature compensation circuit. |
摘要 |
<p>In order to compensate for the effects of temperature variations on a transducer such as a piezo-resistive bridge (1), the bridge is fed from a temperature dependent power supply circuit (6-17). The power supply circuit comprises a temperature sensitive element (11) with first and second adjustment means (16, 15) for adjusting the slope of supply voltage for the transducer against temperature on first and second sides, respectively, of a predetermined temperature. The second adjustment means (15) provides an adjustment which is independent of the first adjustment means so that repeated temperature cycling during calibration is unnecessary.</p> |
