Abstract
Abstract A thermistor, which changes its electrical properties as the temperature it senses changes, is inside and may be sealed within a relatively thin sheath having the capacity to transmit heat to the thermistor substantially without diminution; electrical leads are supported on a supporting substrate; the thermistor is electrically connected between the leads and is mechanically supported by at least one of the leads; the leads connected to the thermistor may be held inside the sheath; the sheath over the sensing element is heat or radiation shrinkable and sealable over the sensing element and the leads; various ways of connecting the thermistor to the leads are disclosed; other sensing elements for sensing other conditions may also be employed.
