Technology development process variable transmitter: current process variable transmitter is the main trend of wireless applications, the application of smaller dimensions and multivariable process transmitter. Since some cement large group of local support processes have adopted wireless technology, wireless transmitters will also be concerned about China's cement industry. The wireless functionality to process variable transmitter is good value for money, taking into account the physical space occupied by some large cement original STG74L pressure, position measurement difficult to install some technology, and some craft measuring point environment is very harsh, with traditional hardwired high installation cost of the device and, if the connection between the elimination of process variable transmitter and the control circuit, use wireless communications to conserve energy imports STG74L pressure to reduce the wiring and maintenance costs STG74L pressure, it will add wireless capabilities to process variable transmitter is value for money. In the new dry process cement production lines STG74L pressure transmitter advantage, as the monitoring of the process variable transmitter eye is very important, it is the accuracy, reliability, stability, security improvement, process control and final product quality continuous improvement of quality to make a contribution.
