Mechanical Pressure Gauges - Copper Alloy And Alloyed Steel, Liquid-filled For Enhanced Protection Against Dynamic Loads And Vibrations, 270-degree Dial Display

Indicating pressure gauges with elastic measuring element are used very extensively to measure pressures in technical applications because they are robust and easy to handle. There gauges incorporate measuring elements which deform elastically under the influence of pressure. Mechanical pressure gauges are produced with bourdon tube, diaphragm and spring elements and are accordingly different. The measuring elements are made of copper alloys, alloyed steels or produced in special materials for specific measuring applications. Pressures are only measurable in conjunction with a reference pressure. The atmospheric pressure alone serves as reference pressure and the pressure gauge shows how much the measured pressure is higher or lower in relation to the given atmospheric pressure (i.e. an overpressure measuring instrument). The pressure is shown in standard measuring ranges over 270 angle degrees on the dial. Liquid-filled pressure gauges offer optimal protection against destruction by high dynamic pressure loads or vibrations as a result of their cushioning. Switching operations can be carried out when combined alarm contacts and output signals (for example 4 ... 20 mA) can be used for industrial process automation in combination with transmitters.
