Drahtloser Drucktransmitter

The wireless pressure transmitter is an intelligent product that integrates pressure, liquid level monitoring, data acquisition, NB, 4G, LoRa wireless communication battery self-powered and other functions. It adopts micro-power wireless communication mode to send the collected signals to the cloud platform or designated IP server through wireless communication for storage and display. The product does not require wiring, and the installation is fast, safe and convenient. It is suitable for pressure monitoring of the production, storage and transportation process of oil and water wells, monitoring of tap water pipe networks, telemetry of water conservancy and hydropower, pressure detection of gas pipelines, and liquid level detection of rivers, lakes and seas.
