<p>A temperature gauge assembly for easy and convenient installation on automotive vehicles and similar powered devices. The preferred form of the temperature gauge assembly comprises a transmission temperature gauge assembly including a gauge unit and a sender unit. The gauge unit is comprised of an outer housing with an electrically responsive meter mounted therein and is provided for conveneint attachment to the dashboard or other suitable location of the vehicle. One terminal of the meter is electrically connected by means of a C-shaped clamp to a fuse terminal or other electrical member of the vehicle connected operatively to the battery of the vehicle. The other terminal of the meter is electrically connected to a sender unit comprising a second C-shaped clamp which is conveniently disposed about an electrically grounded member of the vehicle in heat exchange relationship to the fluid in which temperature is to be measured. In the case of the transmission temperature gauge, the second C-shaped clamp is connected to one of the fluid lines to the automotive vehicle transmission in order to detect temperature conditions thereof. A diode having proper temperature sensitivity and electrical characteristics is secured to the second C-shaped clamp and is, in turn, connected to the meter. In another embodiment of the invention, means are provided for eliminating variation in the voltage from the generator of the vehicle.</p> |
