Differential Pressure Transducers, Model 8310
Electro Mechanical Enterprises, supplier and partner for test, measurement, calibration, production, industrial process automation/control and environmental monitoring systems, offers Differential Pressure Transducers, Model 8310. Application: pressure transducers measure differences in pressure between the two connections of the measuring element. Pressure differences can be measured with respect to a reference pressure, such as atmospheric, or to the command variable of a regulation system. Equally, however, it is possible to measure pressure differences within systems that have a high static pressure. The differential pressure transducers for low pressure ranges may be used to take measurements on systems with line pressures up to 100 bar (or, with the option, up to 345 bar). The line pressure is the maximum static pressure that is permitted simultaneously on both ports of a differential pressure transducer. The result of adding the static pressure to the pressure to be measured must also not exceed the maximum line pressure. For instance, a transducer with a measuring range of 0… +/-100 mbar may be exposed to 100 bar at one pressure port and 99.9 bar at the other, or may have 0 bar at one port and 0.1 bar at the other. It should be noted that when the line pressure changes, the zero point moves. The shift in the zero point is reproducible. It is normal and is compensated for a line pressure of 100 bar. All the differential pressure transducers have mechanical protection against overload. If the measuring range is exceeded by more than 50%, the membrane presses against a stop. Because this stop places a heavy mechanical stress on the membrane, overload should be avoided entirely if at all possible. If, however, overloading does occur, the zero point will move; a change in precision or damage is prevented. Damage will only be caused by frequent or sudden overload.
