Do pressure transmitters have wireless communication? 5

Sino-US Mack MPM6861G intelligent wireless pressure transmitter is a low-power, intelligent instrument with wireless communication function, with advanced industrial-grade MCU as the core, high-quality sensor as the front-end of collection, combined with industrial-grade wireless GPRS data module, Sino-US Mack MPM6861G intelligent wireless pressure transmitter uses China Mobile's mature GPRS network to realize wireless transmission of field instrument data to the cloud. The instrument reports the data according to the set interval, and the customer realizes remote instrument configuration and data query through the web page, and the uploaded and issued data are stored in the database for later query. Through the Internet PC or mobile terminal login to the relevant ** can obtain instrument data, and realize the collection of data statistics, analysis, the formation of reports and data curves, with intuitive, accurate and efficient characteristics.

Based on the extensive coverage of the GPRS public network, the Sino-US Mack MPM6861G intelligent wireless pressure transmitter can realize real-time monitoring of many monitoring points in a large area, such as tap water pipe network pressure, high pool liquid level, environmental parameter detection, hydrological monitoring, etc.

Yes, you can take a look at this is the ZPM3640 wireless intelligent pressure transmitter, and now the manufacturers basically have products as long as there is demand.

Doesn't it mean that transmission line communication can't pass through meters and transformers?

The wireless pressure wheel leakage transmitter system is based on the wireless remote transmission module, which can be combined with our intelligent wireless receiving terminal to form a pressure acquisition system. This system changes the transmission mode of RS485 and 4 20mA current signals and switching power supply mode in most of the previous industries, and adopts lithium battery power supply; In this way, it simplifies the way of installing friends, saves the cost of wiring for customers, and truly achieves the purpose of energy conservation and environmental protection. The product is widely used in various industrial pressure measurement systems, such as oilfield, electric power, petrochemical and some occasions where wiring is inconvenient.

The wireless pressure transmitter system is based on the wireless remote transmission module, which can be combined with our intelligent wireless receiving terminal to form a pressure measurement system. This is the 3rd generation wireless pressure gauge with a transmission distance of more than 1 km.

The wireless pressure sensor is suitable for measuring the pressure value of non-viscous liquids, vapors and gases and other media, and is suitable for long-distance transmission and industrial self-lead attitude system, especially for the occasion without reading conditions. The pressure data in each pipeline is detected by each pressure sensor and wirelessly transmitted to the wireless data base station terminal RTU within 300 meters, and 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.), so as to achieve centralized detection and remote control. It can be widely used in petroleum, chemical, electric power, metallurgy, pharmaceutical, food and other industrial fields, and is an ideal upgrade product for traditional pressure gauges and traditional pressure transmitters, and is an ideal pressure measuring instrument in the field of industrial automation.

The transmitter optimizes the circuit design, power management, and communication protocol, and realizes the "micro-power consumption" design of wireless communication. Micro-emission power and high-sensitivity reception strategy are adopted; It has the function of real-time monitoring of battery power, and automatically alarms when it is lower than the set value, reminding users to replace the battery in time; It has a digital display function, which is convenient for on-site observation and setting, and can set parameters such as collection interval, data sending interval, alarm upper and lower limit on site; Responsible for receiving the instructions of the measurement and control host, and completing the measurement and transmission of pressure data such as oil pressure, sleeve pressure, back pressure, and trunk pressure; It is produced in strict accordance with the technical requirements of the State Radio Regulatory Commission for civil wireless control devices, and the unrestricted 433MHz public channel is used, and there is no need to apply for a dedicated frequency; Code division multiple access modulation allows multiple devices in the same area to transmit data without interfering with each other.
