<p>An electrical sensor device, particularly a pressure sensor device, comprises at least one pressure transducer, (11 to 14), particularly a thick-film transducer, connected to a monitoring circuit (10) arranged to output an electrical signal (V) which is variable in dependence on the pressure (p), an interface circuit (15 to 17) connected to the monitoring circuit (10) and arranged, in response to the said signal (V), to present an output resistance which increases or decreases in accordance with a predetermined response curve, on increase in the pressure (p) detected by the transducers. </p> |
