ABSTRACT:
A vehicle tire gas mass sensor having a sealed cylinder containing a non-toxic and inert gas. The cylinder is sealed at one end with a diaphragm and contains a sealable plug at an opposite end for admitting the inert gas. Sealing is permanent after the introduction of gas. The diaphragm moves freely in response to pressure differential between the inside predetermined pressure of the inert gas and pressure existing in the environment in which sensor is installed. The sensor is defined by a first, second and third contacts which are responsive to diaphragm movement caused by pressure differentials in the cylinder. In turn opening and closing of the contacts actuates alarms for indicating such pressure differential. Equilibrium conditions as between the interior and environment of the sensor are reflected by the movement of diaphragm to compensate for temperature variation occurring at these locations.
