Abstract
A digital pressure gauge includes a casing having a pressure sensitive member which responds when pressure is passed therethrough and a digital display member electrically connected to the pressure sensing member. The gauge includes an insulating rod which engages the pressure sensitive member and which contacts a weight sensing member in response to pressure flowing through an inlet so as to expand the pressure sensitive member.
Claims4
A digital pressure gauge, comprising:
- a casing having a weight sensing member provided therein and a display member electrically connected to said weight sensing member, said display member displaying a weight sensed by said sensing member in digital numbers;
- and
- an expandable air pressure sensitive mechanism provided in said casing and having an inlet in communication with the air pressure mechanism;
- an insulating rod for engaging said air pressure sensitive mechanism and which directly contacts said weight sensing member at a point on a surface of the weight sensing member closest to said pressure sensitive mechanism in response to pressure flowing through the inlet so as to expand the pressure sensitive mechanism.
