The ACD-NB wireless digital pressure transmitter mainly consists of a pressure sensor, signal processing circuit, central processing unit, and wireless communication circuit. It integrates three popular industrial wireless communication methods: ZigBee, LoRa, and NB IoT, using advanced low-power devices and sophisticated software management technology. It has a priority processing mechanism for data alarms, data bursts, instrument failures, battery alarms, etc., ensuring real-time data monitoring and instrument status. It is powered by a large capacity high-performance lithium battery and can work continuously for 2-5 years. Realize remote real-time monitoring, wireless transmission, no need for on-site wiring, saving the trouble of on-site wiring for ordinary instruments, and saving manpower and construction costs. This instrument has advanced design, complete variety and specifications, and is easy to install and use, making it an ideal upgraded product for traditional pressure transmitters.
