Wireless pressure sensor also called wireless pressure transmitter. Wireless pressure sensor acts as a battery-powered pressure measurement monitoring system with the function of measuring the gauge pressure of gases and liquids in a piping.
What the wireless pressure transmitter working principle ?
The wireless pressure transmitter is an industrial pressure transmitter with a wireless remote transmission module added, which can form a pressure acquisition system with our intelligent wireless receiving terminal. This system changes the transmission mode of RS485 and 4~20mA current signal and switching power supply mode in the past, and uses 3.6V lithium battery for power supply; thus simplifies the installation method, saves the cost of customer wiring, and truly achieves energy saving Environmental purpose. This product is widely used in various industrial pressure measuring systems, such as oil field, electric power, petrochemical and some occasions where wiring is inconvenient.
What is the differences among the wireless signals, like Lora, Lorawan, 4G, Nb-Iot etc. ?
To simplify, there are 2 types signal monitoring format. One type is what we will use the wireless pressure transmitters and receivers (gateway) to read the data, usually by computer monitoring software to read all details, such as the Lora and LoraWan. Another type is the upload the monitoring to the cloud by SIM card to read data directly on phone or computer, rather than go through the gateway, this case we mostly see is 4G, Nb-Iot signal type.
How does SenTec wireless Lora pressure sensor/transmitter works ?
Let’s get a overview of SenTec Lora pressure sensor. SenTec Lora sensor manufacturer module based on Germany SEMTECH RF integrated chip with Low Power LAN wireless standard. The name of LoRa is Long Range Radio. Its biggest feature is that it can travel farther than other wireless methods under the same power consumption conditions, realizing the unity of low power consumption and long distance. It consumes 3-5 times longer than the traditional wireless radio communication distance.The LoRa modulation technology is adopted to realize on-site distributed multi-point IOT equipment monitoring and collection. The communication distance can reach 2km, and data from sensors, PLCs, smart meters, etc. can be passed through radio frequency.LoRa radio frequency is mainly used for multi-point and long-distance distributed sensor acquisition and transparent transmission of RS485 serial devices, instruments, and transmitters to the cloud platform.
What is the Lora pressure sensor advantages and disadvantages?
