Temperature sensor
First Claim
1. A temperature sensor comprising an electrical temperature sensing element and at least two high-resistance conductors in sheet form electrically connected to said electrical temperature sensing element , a non-conductive fluorocarbon resin in sheet form being disposed between said conductors , said electrical temperature sensing element being connected to and disposed between said at least two conductors at one end of said assembly adjacent said non-conductive resin sheet , and thereby forming a laminated composite in sheet form, and wherein said laminated composite is vertically separated along its longitudinal axis remote from said temperature sensing element, thereby providing at least a 4-lead temperature sensor.

Abstract
A temperature sensor is provided comprising an electrical temperature sensing element such as a thermistor and a pair of high-resistance conductors of conductive fluorocarbon resin which are electrically connected to the electrical temperature sensing element. The conductors of conductive fluorocarbon resin are disposed on opposite surfaces of a body of fluorocarbon resin. The electrical temperature sensing element may be sandwiched between the pair of high-resistance conductors. Alternatively, the temperature sensor comprises a temperature sensing element held in place and in electrical contact between a pair of conductive fluorocarbon sheets, the sheets being fused one to each side of an electrically insulative sheet of fluorocarbon resin, thereby forming a laminated composite in sheet form, the laminate being vertically separated along its longitudinal axis remote from the temperature sensing element, thereby providing a 4-lead temperature sensor. The temperature sensor thus constructed may be used in microwave therapy as it is less subjected to rejection by human body tissues and does not reflect applied microwaves.
