ABSTRACT:
A digital tire pressure gauge comprises a pressure measuring head to introduce thereinto the tire air. The pressure measuring head extends axially to form a tubular body in which a pressure bearing rod encased by a coil spring is received. The pressure bearing rod is coupled with a pressure converting unit serving to convert the displacement distance of pressure bearing rod into an electronic signal. A pressure displaying unit is connected with the output terminal of the pressure converting unit so as to exhibit thereon in digital form the electronic signal transmitted from the pressure converting unit.
