-The pressures to be compared act on flexible stainless steel diaphragms on either side of the sensing capsule. The two diaphragms are mechanically linked by a rigid connecting rod. To compensate for high static pressures, the cavity between the two diaphragms is filled with hydraulic fluid.
When pressures are equal on both diaphragms, they are at zero position. When there is a difference in pressures acting on the two diaphragms, they are deflected away from the high pressure side, towards the lower pressure side, causing a displacement of the connecting rod.
A precision mechanism translates the linear displacement of the diaphragm connecting rod to angular movement of the gauge’s dial pointer.The connecting rod has intermediate flanges on either side, which protects the diaphragms against excess differential pressure.
When differential pressure exceeds the specified limit, the flange towards the lower pressure side is pressed against the sealing O-ring on the inside of the sensing capsule.
