An electromagnetic diaphragm is a form of capacitive sensor used on an electronic stethoscope. The diaphragm is coated with a conductive material. A conductive plate is positioned behind and parallel to the diaphragm, so that the two conductive elements form a capacitor. Capacitance is a function of plate area, dielectric properties of the space between the conductors, and the distance between the conductors. It is this latter parameter which is modulated by vibration such that the capacitance varies with the distance between the electromagnetic diaphragm and the plate, forming an acoustic sensor.
A special mounting bracket for electromagnetic diaphragm metering pumps

This utility model discloses a special mounting bracket for an electromagnetic diaphragm metering pump, including a vertical column angle steel, a supporting angle steel, a first frame, and a second frame. The vertical column angle steel is vertically arranged, and the first and second frames are respectively fixedly connected to the vertical column angle steel. The first frame is located above the second frame. The supporting angle steel is parallel to the vertical column angle steel, and the first and second frames are respectively fixedly connected to the supporting angle steel. The first and second frames are respectively provided with a first mounting angle steel and a second mounting angle steel. The first and second mounting angle steels are respectively provided with a first aluminum alloy mounting plate and a second aluminum alloy mounting plate. The projection of the first aluminum alloy mounting plate on the horizontal projection plane is staggered from the projection of the second aluminum alloy mounting plate on the horizontal projection plane. This utility model achieves the advantage of convenient and rapid movement of the electromagnetic diaphragm metering pump.
