Dual valve pressure controllers extend the service life

Dual valve pressure controllers extend the service life
Two-valve pressure controller The two pressures of the measured medium pass into the high and low pressure chambers and act on the isolation diaphragms of the delta element (ie, the sensing element), and are transmitted to the measurement through the spacer and the filling liquid in the element. Diaphragm on both sides. Measure the diaphragm and the electrodes on both sides of the insulating sheet to form a capacitor. When the pressures on both sides are inconsistent, the measuring diaphragm is displaced, and the displacement is proportional to the pressure difference. Therefore, the capacitance on both sides is not equal, and the signal is proportional to the pressure through the oscillation and demodulation steps. The dual valve pressure controller and absolute pressure transmitter work in the same way as the differential pressure transmitter, except that the low pressure chamber pressure is atmospheric or vacuum.
Want to know how to guarantee the service life of the double valve pressure controller?
Developing a good habit of regularly maintaining the pressure switch is an important prerequisite for ensuring the service life of the dual valve pressure controller. Today, the manufacturers of the dual valve pressure controller will tell you how to maintain the dual valve pressure controller.
Select the appropriate installation environment
The proper installation environment means that the environment meets the installation requirements of the switch. The first suggestion is to be in a dry and ventilated place. Otherwise, if it is working in a humid environment, it will be very unfavorable to the dual-valve pressure controller. It will not only cause leakage, but also Reduce the service life of the dual valve pressure controller; the temperature should be the appropriate temperature to avoid the temperature is too high or too low, otherwise the excessive temperature will damage the components of the dual valve pressure controller; the second point is to avoid vibration and The interference environment can easily cause measurement errors. Similarly, in the long-term interference environment, the double-valve pressure controller will also have errors.
Carefully clean the internal components
Prior to the dual-valve pressure controller cleaning, using a step-by-step approach, the pressure sensor can be disassembled and cleaned with a cleaning product, otherwise the pressure sensor's diaphragm will be easily damaged. For other internal components, use a soft cloth that will not cause abrasion to gently wipe. When wiping, not only clean the parts that are in direct contact with the measured medium, but also clean the holes to prevent the clogging of the small holes from affecting the pressure switch. The normal operation.
Periodically check components
Maintaining the dual-valve pressure controller is a long-lasting process. In addition to regular cleaning of the pressure switch, it is also necessary to regularly check the various components of the pressure switch and carry out various tests on the components to ensure that the dual-valve pressure controller components can be operated. Guaranteed zero failure.
