Temperature sensor for use in an environment subject to electromagnetic radiation, comprises capacitor which is connected in parallel with the measurement unit in order to by-pass parasitic currents

摘要

The temperature sensor (1) has a body (11) which encloses a temperature sensitive element (3) and interface (71). The element is typically a resistor with a negative temperature characteristic and is connected to the interface by wires (13) and tongues (7). A capacitor (5) is connected between the tongues or the wires to shunt the sensitive element and prevent parasitic currents disturbing the measurements
