Abstract
A thermocouple tilt sensing device comprises a container being substantially gas-tight, a first sensing wire having a first and a second end, and a second sensing wire, having a first and a second end. The first end of the first sensing element is electrically connected to the first end of the second sensing wire thereby forming a thermocouple junction. A heater wire is disposed adjacent the thermocouple junction and is connected to an AC or DC power source. The heater wire provides thermal energy which induces a DC output voltage in the thermocouple. The first sensing wire, second sensing wire and the heater wire are disposed within the sealed container. An angle of a device provided with a thermocouple tilt sensing device is determined by measuring the output voltage from the thermocouple junction and comparing it to a known output voltage curve associated with the thermocouple tilt sensing device.
