This article is reproduced from: http://www.shqyyb.com/news/8921.html Keywords of this article: eja http://www.shqyyb.com/ Inspection content of eja intelligent differential pressure transmitter: The operator should be proficient in installing the differential pressure transmitter, correctly install the circuit and gas line of the differential pressure transmitter, accurately operate the three-valve group, and use a handheld communicator to set and configure the relevant parameters of the differential pressure transmitter. The calibration process of eja intelligent differential pressure transmitter is as follows: 1. Check the equipment and inventory the tools needed. 2. Install the transmitter and connect the circuit and gas circuit. 3. Correctly connect the handheld communicator and complete parameter setting and configuration. 4. Operate the three-valve group correctly. 5. Record the adjustment data, complete corresponding processing and calculations, and complete accuracy verification. 6. Set the reset flag. When adjusting the eja energy differential pressure transmitter, the staff must use a handheld communicator to set and configure the relevant parameters for the adjustment of the differential pressure transmitter, such as: Data such as bit number, unit and range. Different models of differential pressure transmitters use different protocols for calibration. Workers should reasonably select the corresponding handheld device based on the protocol used. For example, when selecting a differential pressure transmitter, you need to select an appropriate handheld communicator according to the transmitter calibration communication protocol. If you choose to use the Hart communication protocol during use, its frequency should be 1.2KHz ； If it is the Brain communication protocol, its frequency should be 2.4KHz. There is no compatibility between these two protocols.
