When the pressure transmitter is installed, it is necessary to perform basic settings on the transmitter. Although it seems irrelevant, it plays a role in setting the core parameters later. The basic settings can be divided into four items. As a qualified instrument operator, you need to set these gradually.
First look at the setting of the process variable: The key to setting the process variable is the determination of the unit. If there is no unit, even if the number is accurate, the measured object cannot be judged. The commonly used variable units are inH2O, bar and inH2O @ 4 ° C, psi and kPa. (One millimeter of water = 9.8 Pa). The unit setting can be found by entering the menu with the communicator, and the unit unit can be found in the basic setting tab.
Next, set the output. 3051T has linear and square root output. Activate the square root output option to make the analog output proportional to the flow.
To the scope reset, the open source nature of this step is a humane sign. The measurement range of the transmitter can be adjusted according to the pressure range on site to ensure the measurement accuracy of the transmitter.
Finally, set the damping. The concept of damping was introduced to reduce the volatility of output readings. The fast input of a Rosemount transmitter affects parameters such as corresponding time, signal stability, and loop dynamics in the system. A suitable damping value is generally set between 0 and 25.6 seconds.
The more experienced an instrument engineer, the more important it is to pay attention to the basic settings of the transmitter before installing the Rosemount 3051T. Knowing the details, we can fully control and control the operating status of the transmitter during subsequent adjustment and maintenance Evaluation.
