Next, the editor from Jiangsu Evergrande Instrument Company will introduce to you the points to note regarding the use of pressure transmitters in vortex flowmeters: First, when measuring steam or other high-temperature media, their temperature should not exceed the maximum allowable temperature for the transmitter; if it is higher than that limit, a cooling device must be used ； Secondly, the medium being measured must not freeze; otherwise, it will damage the diaphragm of the sensor elements, leading to damage to the transmitter. Temperature protection for the transmitter is necessary to prevent freezing ； Third, during the pressure transmission process, the following points should be noted: First of all, ensure there is no air leakage at the connection point between the pressure transmitter and the heat dissipation tube ； Then, before starting to use it, if the valve is closed, it should be opened very carefully and slowly during use, in order to prevent the medium being measured from directly impacting the sensor diaphragm and thus damaging it ； It is also important to ensure that the pipelines remain unobstructed, as deposits in the pipes can be ejected and damage the sensor diaphragm. Fourth, and most fundamentally, never apply a voltage higher than 36V to the transmitter, as this can cause it to be damaged. Never touch the diaphragm with hard objects, as this may cause damage to the isolation diaphragm. Fifthly, when measuring steam or other high-temperature media, a heat dissipation tube should be used to connect the pressure transmitter to the pipeline, and the pressure in the pipeline should be transmitted to the transformer. When the medium being measured is water vapor, an appropriate amount of water must be poured into the heat dissipation tube to prevent overheated vapor from coming into direct contact with the transmitter and damaging the sensor ； For more information, please visit the company’s official website at http://www.yb1518.com/.
