3.How wireless pressure transmitters work
The wireless pressure transmitter has optimized the circuit design, power management, communication protocol, and realized the “micro-power consumption” design of wireless communication. Using micro-transmission power and high-sensitivity receiving strategy, it has the advantages of real-time online monitoring of battery power and so on.
The The wireless pressure transmitter system is mainly composed of a pressure sensor., signal processing circuit, wireless module, power management circuit, battery and antenna. On this basis, a wireless remote transmission module is added, which can form a pressure acquisition system with our intelligent wireless receiving terminal.
This system has changed the transmission mode of RS485 and 4-20mA current signal and the power supply mode of switching power supply in the past, and used 3.6V lithium battery for power supply. This simplifies the installation method and saves the cost of customer wiring. Really achieve the purpose of energy saving and environmental protection.
4.Battery-powered wireless pressure transmitter
The wireless pressure transmitter is a high-precision, low-power radio transmission pressure detection instrument. Powered by a lithium battery, IP65 waterproof cast aluminium casing. Supports data recording and data supplementary transmission functions. No wiring, no external power supply required. Built-in 3.6V lithium battery.
