In each process plant, there may be thousands of points that need to be measured, and saving energy from this aspect can yield unexpected gains. Installing wired pressure, flow, temperature or other transmitters in process plants is often expensive. A wired 4 to 20mA, Profibus, or Foundation fieldbus transmitter requires power, wiring, cable slots, junction boxes, marshals, and control system input or fieldbus communication. If the measurement must be arranged in remote areas, or in hard-to-reach areas such as the top of the tank, the measurement cost of a wired transmitter can be even more astronomical.

Depending on the specific application, wireless transmitters can be installed and connected to the control system for one-fifth to one-third of the cost of wired transmitters. Many process companies use wireless transmitters to save a lot of energy costs and reduce the payback period to just two weeks.
The wireless pressure transmitter detects signs of steam trap operation and sends immediate reports and fault information to the control system. This wireless low-power system is ideal for large-scale use.
The circuit design, power management and communication protocol optimization of the transmitter are carried out, and the “micro power consumption” design of wireless communication is realized. Adopt micro-transmitting power and high sensitivity receiving strategy; With real-time online monitoring of battery power, automatic alarm below the set value, reminding users to replace the battery in time; With digital display function, easy to observe and set, you can set the acquisition interval, data sending interval, alarm upper and lower limits and other parameters on the scene; Responsible for receiving the instructions of the measurement and control host, and completing the measurement and transmission of pressure data such as oil pressure, casing pressure, back pressure and trunk pressure; Production in strict accordance with the technical requirements of the National Radio Regulatory Commission for civil wireless control devices, the use of unrestricted 433MHZ public channels, do not need to apply for a dedicated frequency; Code division multiple access modulation allows multiple devices to transmit data in the same area without interfering with each other.
