The wireless digital pressure transmitter mainly consists of a pressure sensor, signal processing circuit, central processor, and wireless communication circuit. It integrates three popular industrial wireless communication methods: ZigBee, NB-IoT, and LoRa, adopts advanced low-power devices as well as comprehensive software management technology, and features priority handling mechanisms for data alarms, data bursts, instrument faults, and battery alerts, ensuring real-time monitoring of data and instrument status. It is powered by a built-in high-capacity, high-performance lithium battery, capable of continuous operation for 3 to 5 years. It enables remote real-time monitoring and wireless transmission without the need for on-site wiring, eliminating the hassle of wiring required by conventional instruments and saving labor and construction costs.
