Abstract:
1. A vertical pressure sensor comprising: a sensor housing; a pressure application unit coupled to a lower part of the sensor housing and having diaphragm disposed on an upper end thereof and a plurality of strain gauges attached to a top of the diaphragm; a socket surrounding a circumference of the diaphragm such that the socket is spaced apart from the diaphragm by a predetermined distance, the socket having a receiving passageway corresponding to an upper end of the diaphragm; a plurality of electrode terminals disposed at an upper end of the socket in a Wheatstone bridge, one end of each of the plurality of electrode terminals exposed through the receiving passageway and electrically connected to a corresponding one of the plurality of strain gauges by wire bonding, another end of each of the plurality of electrode terminals protruding from the upper end of the socket to constitute an electrode tip; a circuit board connected to the plurality of electrode terminals and outputting an electrical signal indicative of a measured pressure value; and a plurality of electrical signal transmitting electrode rods connected to a top of the circuit board.
