The wireless pressure transmitter is based on this and adds a wireless remote transmission module, which can form a pressure acquisition system with our intelligent wireless receiving terminal. This system changes the previous transmission mode of RS485 and 4-20mA current signal and the switching power supply mode used in most industries, and adopts a 3.6V lithium battery for power supply; thus simplifying the installation method, saving the cost of customer wiring, and truly achieving the purpose of energy saving and environmental protection. This product is widely used in various industrial pressure measurement systems, such as oil fields, electric power, petrochemicals and some occasions where wiring is inconvenient.

The transmitter has been optimized in circuit design, power management, and communication protocol, and has realized the "micro-power consumption" design of wireless communication; wireless pressure transmitter adopts micro-transmitting power and high-sensitivity receiving strategy; it has the function of real-time online monitoring of battery power, and automatically alarms when it is lower than the set value, reminding users to replace batteries in time; it has a digital display function, which is convenient for on-site observation and setting, and parameters such as collection interval, data transmission interval, upper and lower alarm limits can be set on-site; it is responsible for receiving instructions from 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; it is produced in strict accordance with the technical requirements of the State Radio Management Committee for civil wireless control devices, using the unrestricted 433MHZ public channel, without the need to apply for a dedicated frequency; it adopts code division multiple access modulation, allowing multiple devices in the same area to transmit data without interfering with each other.

Wireless pressure sensors are suitable for measuring the pressure of non-viscous liquids, steam, gas and other media. They are suitable for long-distance transmission and industrial automation system matching, especially for occasions without reading conditions. Each wireless pressure transmitter detects the pressure data in each pipeline and transmits it wirelessly to the wireless data base station terminal RTU within a range of 300 meters. The RTU can upload the data to the central control room through wireless communication equipment (such as SCDMA, GPRS, CDMA or data transmission radio, etc.), thereby realizing centralized detection and long-distance control. It can be widely used in industrial fields such as petroleum, chemical, electric power, metallurgy, pharmaceutical, and food. It is an ideal upgrade product for traditional pressure gauges and traditional pressure transmitters, and an ideal pressure measuring instrument in the field of industrial automation.
