Detailed content
- Functional Characteristics:
- The channel – by – channel isolation design can effectively prevent cross – talk between signals and ensure the accuracy of data collection in complex industrial environments.
- It has a built – in high – precision signal conditioning circuit and A/D converter, which can accurately convert analog signals into digital signals.
- It supports HART protocol communication, which can read the diagnostic information and configuration parameters of the field smart transmitter while collecting analog signals.
- It has an online calibration function, which can complete the calibration of the module without stopping the system operation, reducing the impact on the production process.
- The process power monitoring function can monitor the power supply status of the field transmitter in real – time and send an alarm when the power supply is abnormal.
- Application Scenarios: It is widely used in the collection of temperature, pressure, and flow signals of reaction kettles and pipelines in the chemical industry; the monitoring of steam parameters and water quality indicators in the power industry; the data collection of various production process parameters in the oil and gas exploration and development process; and the monitoring of environmental parameters in the environmental protection industry.
