The PTL578G wireless pressure transmitter is a low-power intelligent instrument that integrates pressure measurement, transmission, and reporting based on the 4G wireless communication network. Integrated with high-sensitivity pressure detection components, high-precision signal conditioning circuits, low-power battery power management, and a rich LCD display interface. Suitable for smart city application scenarios such as oil fields, water conservancy, fire protection pipelines, water supply pipelines, and urban heating pipelines. Periodically report pressure measurement values, battery level, signal quality, and other data, and be able to promptly alert when the pressure exceeds the set range, giving early warning of potential faults. And support data access services for third-party platforms.
