Embodiment Construction

[0019] In addition to the one or more preferred embodiments disclosed below, the invention is capable of other embodiments and of being practiced or carried out in various ways. It is therefore to be understood that the invention is not limited in its application to the details of construction and construction of the components set forth in the following description or shown in the drawings. Even though only one embodiment is described herein, the claims should not be limited to that embodiment. Furthermore, its claims should not be read strictly unless there is clear and convincing evidence that certain exceptions, limitations, or disclaimers exist.

[0020] As discussed in the Background of the Invention section, temperature sensors that are subjected to extremely high temperatures and frequently experience extreme temperature differences often deteriorate, and / or consequently fail over time. The present invention provides an improved temperature sensor that is better able ...

Abstract

A temperature sensor includes a probe section for insertion into a hot zone. The probe section includes a thermistor, a first lengthy pin terminating at the thermistor, and a second lengthy pin also terminating at the thermistor. A housing section is on one end of the probe section and outside of the hot zone. The housing section includes a first spring which biases the first pin into contact with the thermistor, a second spring which biases the second pin into contact with the thermistor, a first electrical contact engaged with the first spring, and a second electrical contact engaged with the second spring.

Description

technical field [0001] The invention relates to a temperature sensor comprising a thermistor. Background technique [0002] Various types of devices have been used as temperature sensors to measure the temperature of different environments. In areas of high temperature or "hot zone", the operation of these devices is problematic. Part of the temperature sensor, such as a thermistor, must be placed within the hot zone in order to detect temperature, and even within the hot zone, there can be large and frequent temperature differences. Measurement or control circuits and wires must be placed outside the hot zone, ie in the low temperature zone, to prevent damage. However, a portion of the sensor must traverse two regions in order to maintain an electrical connection between the thermistor and associated circuitry. [0003] Those skilled in the art have attempted to provide relief from excess pressure and stress caused by the high temperature and considerable operating tempe...
