The PT124B-289 series pressure transmitters are self-developed low-power wireless transmission digital pressure transmitters by Shanghai Chaohui, powered by batteries. This series offers various wireless transmission methods, including options such as GPRS, LoRa, NB-IoT, and ZigBee.
Wireless digital pressure transmitters with GPRS transmission, leveraging China Mobile's mature GPRS network, upload pipeline pressure data to the cloud. Users can match IP addresses and other standard parameters on-site or remotely. LoRa transmission wireless digital pressure transmitters, when used with LoRa gateways, offer advantages such as low power consumption, long transmission range, strong signal penetration, and self-organizing networks.
